CISCO-IETF-PW-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.

     DESCRIPTION 
         "This MIB contains managed object definitions for Pseudo 
          Wire operation as in: Pate, P., et al, <draft-ietf-pwe3- 
          framework>, Xiao, X., et al, <draft-ietf-pwe3- 
          requirements>, Martini, L., et al, <draft-martini- 
          l2circuit-trans-mpls>, and Martini, L., et al, 
          <draft-martini-l2circuit-encap-mpls>. 

          The indexes for this MIB are also used to index the PSN- 
          specific tables and the VC-specific tables. The VC Type 
          dictates which VC-specific MIB to use. For example, a  
          'cep' VC Type requires the use the configuration and status  
          tables within the CEP-MIB. 

          This MIB enable the use of any underlying packet switched  
          network (PSN). Specific tables for the MPLS PSN is 
          currently defined in a separate CISCO-IETF-PW-MPLS-MIB. 
          Tables to support other PSNs (IP, L2TP for example) will 
          be added to this MIB in future revisions. 

          At the time of publication of this version, there are no  
          PWE3 WG documents for all features and objects in this MIB, 
          and the MIB is therefore subject to change based on the WG  
          progress."
