CISCO-L2L3-INTERFACE-CONFIG-MIB device MIB details by Cisco

CISCO-L2L3-INTERFACE-CONFIG-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.

CL2L3InterfaceMode ::= TEXTUAL-CONVENTION
    STATUS        current
    DESCRIPTION
        "The operational mode of the interface.

        For administrative and operational states, valid values are: 
        routed(1), switchport(2).
        
        routed(1): Routed mode interfaces direct traffic using 
        layer 3 protocols.

        switchport(2):  Switchport-mode interfaces direct traffic using 
        layer 2 protocols.  A switchport-mode interface can be in
        access mode, or trunk mode, or multi-mode.

        Switchport interface operating mode can be configured manually,
        or negotiated by Dynamic Trunking Protocol (DTP) or Dynamic 
        Inter-Switch Link (DISL).

        Access-mode interfaces carry one VLAN's traffic.  Access-mode
        interface parameters are configured in CISCO-VLAN-MEMBERSHIP-MIB.

        Trunk-mode interfaces carry one or more VLANs.  VLAN-related 
        trunk-mode interface parameters are configured in CISCO-VTP-MIB.

        Multi-mode interfaces carry one VLAN to each alias of a 
        single connected end-station.  VLAN-related multi-mode 
        interface parameters are configured in CISCO-VTP-MIB.
