CTRON-Q-BRIDGE-MIB-EXT device MIB details by Enterasys Networks Inc

CTRON-Q-BRIDGE-MIB-EXT 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.

    DESCRIPTION
            "This MIB module defines a portion of the SNMP enterprise
             MIBs under the Cabletron enterprise OID pertaining to 
             the configuration of switches that support IEEE 802.1Q
             [802.1Q] and the Q-BRIDGE-MIB [RFC2674]."

    REVISION    "200312152053Z"  -- Mon Dec 15 20:53 GMT 2003
    DESCRIPTION "Added ctDot1qPortReplaceTCI to allow the optional
                 replacement of the original Tag Control Information
                 (TCI) in an 802.1Q tagged frame."

    REVISION    "200207262045Z"  -- Fri Jul 26 20:45 GMT 2002
    DESCRIPTION "Changed the description of
                 ctDot1qVlanForbidEgressPorts."

    REVISION    "200207191412Z"  -- Fri Jul 19 14:12 GMT 2002
    DESCRIPTION "Added the ctDot1qVlanCurrentExtTable.
                 Changed CONTACT-INFO clause to Enterasys Networks."

    DESCRIPTION "Minor grammatical changes."

    REVISION    "200101101329Z"
    DESCRIPTION "Added the ctDot1qPortDiscardTagged leaf for additional 
                 backwards compatibility with the now obsolete
                 CTRON-VLAN-EXTENSIONS-MIB.  Fixed the INDEX clause of
                 the ctDot1qVlanDynamicEgressEntry.  Added the new
                 ctQBridgePortGroup2 OBJECT-GROUP and ctDot1qVlan2 
                 MODULE-COMPLIANCE.  Deprecated the ctQBridgePortGroup
