CISCO-SDLLC-MIB 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.

   Overview of SDLLC conversion MIB
   
  
   MIB description                        
   The SDLLC MIB includes read-only configuration and operational
   information on Cisco's implementation of SDLC to LLC2 media
   translation.  The following example shows the entities managed
   by the SDLLC MIB.
  
  
    FEP/ ==  Token == CISCO A == WAN/RSRB == CISCO B == Serial == SDLC  
    Host     Ring                                       line      station
  
     |=============== LLC2 session ============|=== SDLC session ====|
     
     In this example configuration, CISCO B is performing the SDLLC 
     conversion, and so we query CISCO B for this MIB.
     The SDLC device believes it is talking to the host via a direct
     SDLC session.  The host believes it is talking to the SDLC station on 
     the same token ring.  CISCO A is also unaware of the SDLLC conversion
     going on at CISCO B; it just believes it has an RSRB session with 
     its peer CISCO B to bridge two token ring separated by a WAN.
     So CISCO B is the only agent that can provide the SDLLC conversion
     details.  We can combine this MIB with the CISCO-RSRB-MIB from
     either CISCO A or CISCO B to get a better picture of the network.
     
     This MIB has two tables:  
     
     convSdllcPortTable has an entry for each serial interface for 
     general SDLLC information on an interface, such as administered 
     virtual MAC addresses and virtual ring and bridge numbers.
     This table is indexed by ifIndex.
     
     convSdllcAddrTable has an entry for each serial interface and
     SDLC address pair.  It contains information specific to an SDLC
     address on an interface, such as the partner MAC address, 
     XID value, and address state.  This table is indexed by ifIndex
     and convSdllcAddrSdlcAddr (the address of the SDLC station).
 
     The above configuration would have a single entry in each table.
     If CISCO B had two serial lines configured for sdllc conversion, 
     there would be two entries per table.  If there
     were only one serial line, but it was multipoint and
     supported two sdlc addresses on the other end of the 
     line, there would be a single entry in convSdllcPortTable, and
     two entries in convSdllcAddrTable.
     
     The MIB provides the following information for convSdllcPortTable:
     
     convSdllcPortVirtMacAddr - The locally administered MAC addressed
       assigned to the serial interface.  Note that this address must
       always end in '00'.  CISCO B replaces the 00 with the sdlc
       address of the serial device.  For a multipoint configuration
       with two SDLC stations the llc2 side will 'see' two token ring 
       stations with unique MAC addresses on the sdlc side.
     convSdllcPortVirtRing - The locally administered token ring number
       assigned to the serial interface.  This gives the serial interface
       a token ring appearance to the llc2 side of the conversion, so
       that it appears that it is a token ring on the other side of
       a bridge.
     convSdllcPortBridge - The bridge number assigned to CISCO B 
     convSdllcPortLlc2Ring - The token ring number on the LLC2 session
       side.  In this case it is the RSRB virtual ring group number
       between CISCO A and CISCO B.  
     convSdllcPortLocalAck - indicates whether local acknowledgement
       of SDLLC sessions is active.        
     convSdllcPortLocalAckState - indicates the state of
      the local acknowledgement session.   
     convSdllcPortMaxLlc2FrameSize - the largest I-frame size that
       can be sent or received on the LLC2 session.
 
     The MIB provides the following information for convSdllcAddrTable:
     convSdllcAddrSdlcAddr - The address of the SDLC station.
     convSdllcAddrPartnerMacAddr - The MAC address of the FEP, as
       specified with the sdllc partner command.
     convSdllcAddrXID - The IDBLK and IDNUM of the SDLC station;
       these must match the VTAM configured values
     convSdllcAddrState - indicates the state of the SDLLC conversion
     convSdllcAddrMaxSdlcFrameSize - the largest I-frame size that
       can be sent or received on the SDLC session.
