Pseudowire LSP Sharing MIB

By implementing the tables in PW LSP sharing MIB, the SNMP manager is able to observe the transmit packet counters over each LSP that is configured for used by the PW, and aggregated transmit and receive packet counters over PW itself. It consist three tables:
  • extremePwPerfTable
  • extremePwLspOutboundMappingTable
  • extremePwLspPerfTable

    There are no standard MIB tables and scalars objects that can be used for Pseudo Wire LSP Sharing. MIB table and object defined here are Extreme Networks proprietary. These three table are implemented in code/ l3protocol/mpls/src/extrememplsmib.my.

    A new SNMP MIB object is introduced for PW LSP Load Sharing: extremePwObjects OBJECT IDENTIFIER ::= { extremeMplsMIB 5 }

extremePwPerfTable

This table contains the aggregated transmit and receive packet counters for in-service PWs.

extremePwLspOutboundMappingTable

This table provides the mapping between PWs and LSPs by providing an LSP index. LSP indexes are assigned uniquely for each PW. Entries in this table indicate that an LSP is being used by an in-service PW. An SNMP notification will be sent when an entry is added or deleted.

MIB Object Description Variable Type Support Status
lspIndex LSP index per LSP used by the PW. It is only unique per PW peer. Index Supported
pwLspOutboundLsrXcIndex Corresponding entry in the MPLS-LSR-STD-MIB Read Supported
pwLspOutboundTunnelIndex Corresponding RSVP-TE tunnel index based on LSP index used by the PW Read Supported
pwLspOutboundTunnelInstance Corresponding RSVP-TE tunnel instance based on LSP index used by the PW Read Supported
pwLspOutboundTunnelLclLSR Corresponding RSVP-TE tunnel ingress LSR ID based on LSP index used by the PW Read Supported
pwLspOutboundTunnelPeerLSR Corresponding RSVP-TE tunnel egress LSR ID based on LSP index used by the PW Read Supported
pwLspOutboundTunnelTypeInUse LSP Type used by the PW. mplsTe value (MIB definition is 1) is being used for RSVP-TE LSPs, and mplsNonTe value (MIB definition is 2) is being used for Static or LDP LSPs. Read Supported

extremePwLspPerfTable

This table contains the transmit packet and byte counters for traffic sent over a specific PW using a specific LSP.

MIB Object Description Variable Type Support Status
pwLspPerfOutPackets Receive packet counter per LSP used by the PW. Index Supported
pwLspPerfOutBytes Receive packet counter in bytes per LSP used by the PW. Read Supported
pwLspPerfOutHCPackets Receive high capacity packet counter per LSP used by the PW. Read Supported
pwLspPerfOutHCBytes Receive high capacity packet counter in bytes per LSP used by the PW. Read Supported
