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.


MIB Object	Description	Variable Type	Support Status
pwPerfInPackets	Receive packet counter per PW	Read	Supported
pwPerfInBytes	Receive packet counter in bytes per PW	Read	Supported
pwPerfOutPackets	Transmit packet counters per PW	Read	Supported
pwPerfOutBytes	Transmit packet counter in bytes per PW	Read	Supported
pwPerfInHCPackets	Receive high capacitypacket counter per PW	Read	Supported
pwPerfInHCBytes	Receive packet counter in bytes per PW	Read	Supported
pwPerfOutHCPackets	Transmit packet counters per PW	Read	Supported
pwPerfOutHCBytes	Transmit packet counter in bytes per PW	Read	Supported

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
