Nortel-Magellan-Passport-BridgeMIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

This group of attributes is applicable to all types of bridge ports and represent the common factor between them. These attributes influence the working of a bridge port." ::= { vrPpTbcl 10 } vrPpTbclProvEntry OBJECT-TYPE SYNTAX VrPpTbclProvEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "An entry in the vrPpTbclProvTable." INDEX { vrIndex, vrPpIndex, vrPpTbclIndex } ::= { vrPpTbclProvTable 1 } VrPpTbclProvEntry ::= SEQUENCE { vrPpTbclTranslateIpx INTEGER, vrPpTbclFragmentIp INTEGER, vrPpTbclServiceClass INTEGER, vrPpTbclConvertArpMacAddress INTEGER, vrPpTbclPortNum Unsigned32, vrPpTbclOutboundFrameMediaType INTEGER } vrPpTbclTranslateIpx OBJECT-TYPE SYNTAX INTEGER { off(0), ieee8023(1), ethernet(2), snap(3), sap(4) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the type of translation to be performed on frames carrying IPX packets. Ethernet frames carrying IPX payload could be translated to IEEE 802.3 frames (with the same IPX payload) or vice- versa. The main reason to do so is to allow the bridge unit to consistently forward one type of frames carrying IPX packets. Translations can be turned off altogether in which case the IPX frames will pass through the bridge unit unchanged." DEFVAL { off } ::= { vrPpTbclProvEntry 1 } vrPpTbclFragmentIp OBJECT-TYPE SYNTAX INTEGER { off(0), on(1) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies if or not outbound frames carrying IP datagrams should be fragmented to conform to message transfer unit (mtu) sizes dictated by the media." DEFVAL { off } ::= { vrPpTbclProvEntry 2 } vrPpTbclServiceClass OBJECT-TYPE SYNTAX INTEGER { ordered(0), notOrdered(1) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies if the frames should be ordered or not before they are transmitted through a bridge port. If this attribute has a value of ordered the received frames are ordered as in the original message, before they are transmitted out through a bridge port. If it has a value of notOrdered, received then frames pass through the bridge unit in the order they are received. This feature can be used over multiple telecommunication links to increase data flow. Please note that this attribute only affects link protocols and is ineffective with lan media." DEFVAL { notOrdered } ::= { vrPpTbclProvEntry 3 } vrPpTbclConvertArpMacAddress OBJECT-TYPE SYNTAX INTEGER { off(0), on(1) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute is indicative of the state of the MAC address format conversion process for ARP/RARP frames. The MAC addresses may be translated if need be from a canonical format to a non-canonical format, based on the needs of the associated media. If this attribute is set to a value of on then all Mac addresses will converted if need be to suit the format of mac address, the outgoing media will support. If this attribute is set to a value of off no such conversion takes place." DEFVAL { off } ::= { vrPpTbclProvEntry 4 } vrPpTbclPortNum OBJECT-TYPE SYNTAX Unsigned32 (0..255) ACCESS read-only STATUS mandatory DESCRIPTION "This attribute is indicative of the unique number assigned to the bridge port. It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures. If a port is deleted then re-added under the same protocol port, CAS treats the change as a SET to the portNum attribute." DEFVAL { 0 } ::= { vrPpTbclProvEntry 5 } vrPpTbclOutboundFrameMediaType OBJECT-TYPE SYNTAX INTEGER { unaltered(1), ethernetConv(2) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the media type the frame must be in before it is to be forwarded over the outbound supported WAN Bridge Protocol Port. The attribute only applies to outbound Bridge Protocol Port. For supported bridge ports, if the attribute value remains set to the default value of unaltered then there will be no frame conversion. When the value is set to the value ethernetConv then all frames being forwarded out the outbound WAN Port will be converted to ethernet before forwarding takes place. The only outbound WAN medias that currently support conversion are: FR (Frame Relay) and VNS. All other medias will fail the Bridge Port semantic check when attempts are made to alter this attribute. The following is an example of what the user may be able to do. Frames originating from a Token Ring are to be flooded out onto another Token Ring and a Frame Relay Port. The token ring Outbound port performs no translation, yet the FR Port has the outboundFrameMediaType attribute set to ethernetConv which results in the frame being translated into Ethernet format from Token Ring format before Frame Relay does its encapsulation and transmits over the FR port." DEFVAL { unaltered } ::= { vrPpTbclProvEntry 6 } vrPpTbclTbProvTable OBJECT-TYPE SYNTAX SEQUENCE OF VrPpTbclTbProvEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "This group houses all the port specific provisionable attributes that belong to the Tb group.

The secure feature, if enabled causes the following things to happen: a) disallows dynamic learning, b) disallows frames to be forwarded that do not satisfy the following condition: the mac address of the source should be found in the forwarding table and the destination mac address of the frame should also be found in the forwarding table. In addition to this, the port the frame was received on should figure as the in port, given the destination mac address found in the frame. c) disallows frames to be forwarded if the allowed to go port map for the destination mac address is empty. This feature in effect allows the user to choose the hosts that can generate traffic and the hosts that can receive traffic through this bridge unit." DEFVAL { disabled } ::= { vrPpTbclTbProvEntry 1 } vrPpTbclStpProvTable OBJECT-TYPE SYNTAX SEQUENCE OF VrPpTbclStpProvEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "This group houses all the port specific provisionable attributes that belong to the Stp group.

DEFVAL { up } ::= { vrPpTbclStpProvEntry 1 } vrPpTbclPortStateStpControl OBJECT-TYPE SYNTAX INTEGER { off(0), on(1) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies whether or not spanning tree protocol state for this bridge port is controlled by the spanning tree protocol. In essence it indicates the participation of this bridge port in the spanning tree protocol, by accepting and acting on received bridge protocol data units and by sending out the same. on signifies that this bridge port's spanning tree port state is controlled by the spanning tree protocol. A value of off signifies that the spanning tree port state of this bridge port is unaffected by the spanning tree protocol. This in effect puts the bridge port out of reach of the spanning tree protocol and in the forwarding state. Care should be taken while assigning a value of off to this attribute, as this might cause network loops. Please do not set this attribute to off unless you are absolutely sure about the effect of such an action on your network topology." DEFVAL { on } ::= { vrPpTbclStpProvEntry 2 } vrPpTbclStpTypeProv OBJECT-TYPE SYNTAX INTEGER { dec(2), ieee8021(3) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the type of spanning tree protocol the port is participating in. A bridge port could participate in either the ieee8021 spanning tree protocol or the dec spanning tree protocol. If the value of the attribute protocolSpec in the SpanningTreeProtocol component, provisioned under the TransparentBridge component is in conflict with the value of this attribute, the value of the protocolSpec attribute will prevail. Prevailing stp type is reflected in the value of the attribute stpTypeOper." DEFVAL { ieee8021 } ::= { vrPpTbclStpProvEntry 3 } vrPpTbclPortPriority OBJECT-TYPE SYNTAX Unsigned32 (0..65535) ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the value for port priority, which is contained in the first octet of the port identifier.

DEFVAL { 128 } ::= { vrPpTbclStpProvEntry 4 } vrPpTbclPathCost OBJECT-TYPE SYNTAX Unsigned32 (1..65535) ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the contribution of this port, to all the paths to the root bridge that include this port. Please note that the value of the attribute pathCostMethod is applied only when the value of the attribute pathCostMethod is set to on and is ignored if otherwise." DEFVAL { 10 } ::= { vrPpTbclStpProvEntry 5 } vrPpTbclPathCostMethod OBJECT-TYPE SYNTAX INTEGER { off(1), dec(2), ieee8021(3) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the method used by the bridging logic, to calculate the path cost to the bridge considered to be the root bridge in the spanning tree topology.

Domain numbers are used for confining frames to a domain. Domain based filtering provides a complete segregation of traffic based on domain number associated with frames. There can exist only sixteen domains when a spanning tree is desired specific to each domain. When there is only a single spanning tree spanning all the domains the maximum number of domains possible are 4294967293. This attribute is of no relevance when associated with backbone bridge port. Its value is ignored in such a situation." DEFVAL { 1 } ::= { vrPpTbclDIProvEntry 1 } vrPpTbclPreserveDomain OBJECT-TYPE SYNTAX INTEGER { off(0), on(1) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies if the domain information should be preserved or embedded in the frame header. This attribute applies only to backbone ports and does not affect the access bridge ports. By setting this attribute to a value of on, domain information could be preserved in frames being tunnelled across the a backbone, so that this information can be deciphered at the other end of the backbone tunnel. This preserves the integrity of the domains thus preventing domain breaches while tunnelling frames across backbone network. If the value of this attribute is set to off then domain information is not preserved in the header of the frames tunnelling through the backbone. This eliminates the overhead incurred to preserve domain information across the backbone while tunnelling frames across it. Preserve domain is relevant when used in conjunction with the following media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when used with other types of media." ::= { vrPpTbclDIProvEntry 2 } vrPpTbclStateTable OBJECT-TYPE SYNTAX SEQUENCE OF VrPpTbclStateEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "This group contains the three OSI State attributes.

It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures.

The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures.

DEFVAL { off } ::= { vrPpSrBpProvEntry 4 } vrPpSrBpPortNum OBJECT-TYPE SYNTAX Unsigned32 (0..255) ACCESS read-only STATUS mandatory DESCRIPTION "This attribute is indicative of the unique number assigned to the bridge port. It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures. If a port is deleted then re-added under the same protocol port, CAS treats the change as a SET to the portNum attribute."

The attribute only applies to outbound Bridge Protocol Port. For supported bridge ports, if the attribute value remains set to the default value of unaltered then there will be no frame conversion. When the value is set to the value ethernetConv then all frames being forwarded out the outbound WAN Port will be converted to ethernet before forwarding takes place. The only outbound WAN medias that currently support conversion are: FR (Frame Relay) and VNS. All other medias will fail the Bridge Port semantic check when attempts are made to alter this attribute. The following is an example of what the user may be able to do. Frames originating from a Token Ring are to be flooded out onto another Token Ring and a Frame Relay Port. The token ring Outbound port performs no translation, yet the FR Port has the outboundFrameMediaType attribute set to ethernetConv which results in the frame being translated into Ethernet format from Token Ring format before Frame Relay does its encapsulation and transmits over the FR port."

It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures.

The attribute only applies to outbound Bridge Protocol Port. For supported bridge ports, if the attribute value remains set to the default value of unaltered then there will be no frame conversion. When the value is set to the value ethernetConv then all frames being forwarded out the outbound WAN Port will be converted to ethernet before forwarding takes place. The only outbound WAN medias that currently support conversion are: FR (Frame Relay) and VNS. All other medias will fail the Bridge Port semantic check when attempts are made to alter this attribute. The following is an example of what the user may be able to do. Frames originating from a Token Ring are to be flooded out onto another Token Ring and a Frame Relay Port. The token ring Outbound port performs no translation, yet the FR Port has the outboundFrameMediaType attribute set to ethernetConv which results in the frame being translated into Ethernet format from Token Ring format before Frame Relay does its encapsulation and transmits over the FR port."

Ethernet frames carrying IPX payload could be translated to IEEE 802.3 frames (with the same IPX payload) or vice- versa. The main reason to do so is to allow the bridge unit to consistently forward one type of frames carrying IPX packets. Translations can be turned off altogether in which case the IPX frames will pass through the bridge unit unchanged."

If this attribute has a value of ordered the received frames are ordered as in the original message, before they are transmitted out through a bridge port. If it has a value of notOrdered, received then frames pass through the bridge unit in the order they are received.

DEFVAL { notOrdered } ::= { vrPpSrseProvEntry 3 } vrPpSrseConvertArpMacAddress OBJECT-TYPE SYNTAX INTEGER { off(0), on(1) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute is indicative of the state of the MAC address format conversion process for ARP/RARP frames. The MAC addresses may be translated if need be from a canonical format to a non-canonical format, based on the needs of the associated media. If this attribute is set to a value of on then all Mac addresses will converted if need be to suit the format of mac address, the outgoing media will support. If this attribute is set to a value of off no such conversion takes place." DEFVAL { off } ::= { vrPpSrseProvEntry 4 } vrPpSrsePortNum OBJECT-TYPE SYNTAX Unsigned32 (0..255) ACCESS read-only STATUS mandatory DESCRIPTION "This attribute is indicative of the unique number assigned to the bridge port. It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures. If a port is deleted then re-added under the same protocol port, CAS treats the change as a SET to the portNum attribute." DEFVAL { 0 } ::= { vrPpSrseProvEntry 5 } vrPpSrseOutboundFrameMediaType OBJECT-TYPE SYNTAX INTEGER { unaltered(1), ethernetConv(2) } ACCESS read-write STATUS mandatory DESCRIPTION "This attribute specifies the media type the frame must be in before it is to be forwarded over the outbound supported WAN Bridge Protocol Port. The attribute only applies to outbound Bridge Protocol Port. For supported bridge ports, if the attribute value remains set to the default value of unaltered then there will be no frame conversion. When the value is set to the value ethernetConv then all frames being forwarded out the outbound WAN Port will be converted to ethernet before forwarding takes place. The only outbound WAN medias that currently support conversion are: FR (Frame Relay) and VNS. All other medias will fail the Bridge Port semantic check when attempts are made to alter this attribute. The following is an example of what the user may be able to do. Frames originating from a Token Ring are to be flooded out onto another Token Ring and a Frame Relay Port. The token ring Outbound port performs no translation, yet the FR Port has the outboundFrameMediaType attribute set to ethernetConv which results in the frame being translated into Ethernet format from Token Ring format before Frame Relay does its encapsulation and transmits over the FR port."

In essence it indicates the participation of this bridge port in the spanning tree protocol, by accepting and acting on received bridge protocol data units and by sending out the same. on signifies that this bridge port's spanning tree port state is controlled by the spanning tree protocol. A value of off signifies that the spanning tree port state of this bridge port is unaffected by the spanning tree protocol.

It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures.

The following is an example of what the user may be able to do. Frames originating from a Token Ring are to be flooded out onto another Token Ring and a Frame Relay Port.

It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time. The portNum is set as component critical since bridging also uses the port number as a key for indexing into its data structures.

The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view. This is necessary since there is no guarantee of order when processing changes to multiple protocol ports so without the pending deletion state, the same port number could be temporarily assigned to two ports for a short period of time.

It is used for SNMP management of this bridge port and in spanning tree as an identifier this bridge port. Notes regarding portNum: Escape routines exist for initializing, copying, and deleting port numbers. This is necessary because SNMP requires a unique port instance identifier. The initPortNum escape routine sets the port number to a value in the range 1-255 for this purpose. The setCopiedPortNum escape routine exists to maintain the uniqueness of the port number in cases when one port is copied to another. When a bridge port is deleted, the releasePortNum escape routine places the port number being released into a pending deletion state. This is because the port number cannot be re-allocated until the port is truely deleted in the current view.

The following is an example of what the user may be able to do. Frames originating from a Token Ring are to be flooded out onto another Token Ring and a Frame Relay Port. The token ring Outbound port performs no translation, yet the FR Port has the outboundFrameMediaType attribute set to ethernetConv which results in the frame being translated into Ethernet format from Token Ring format before Frame Relay does its encapsulation and transmits over the FR port."
