IXP MPLS Enhancements

ExtremeXOS Release 15.4 adds the following IXP MPLS (Multiprotocol Label Switching) feature enhancements:

EMS logs reflect the operation status changes of LSPs, PWs, and Interfaces.
Show command displays details for transit and egress RSVP-TE LSPs.
Metaswitch fixpack enhances logging of PATH failures.
RSVP-TE description field now displays LSP Name/Path.
MPLS commands are added to “show tech-support” functionality.
Add support for the Metaswitch dmptrace facility.

EMS Logging of MPLS Protocols, LSPs, PWs, and Interfaces

The following EMS logs allow you to track MPLS protocols, some LSPs, and PW and MPLS I/F operational states. These logs are added at the “Info” level, and are not generated in the default log output (the default level for MPLS is “Warning”).

LSPs

MPLS.ChgStaticIngrLSPState
MPLS.ChgStaticTrnstLSPState
MPLS.ChgStaticEgrLSPState
MPLS.RSVPTE.ChgIngrLSPState

PWs

MPLS.L2VPN.ChgPWState

MPLS Protocol Interfaces

MPLS.ChgIfState
MPLS.ChgProtoState
MPLS.LDP.ChgProtoState
MPLS.RSVPTE.ChgProtoState

Note

CES.TDM.PWUp and CES.TDM.PWDown EMS logs already exist.

Enhanced Show Details for Transit and Egress RSVP-TE LSPs

The following fields are added to the show mpls rsvp-te lsp command output on transit and egress nodes:

Administrative & Operational Statuses
Setup & Hold Priorities

Enhance Usability and Ability to Debug MPLS

Apply fixpack to provide better debugging for RSVP-TE Path message handling
Use RSVP-TE “Tunnel Description” field in MPLS TE MIB to indicate LSP and Path
Because primary and secondary RSVP-TE LSPs use the same LSP name, and the idea of Redundant LSPs is an EXOS feature, determining which path is associated with an LSP could only be done through the CLI. To eliminate this problem, the RSVP-TE “Tunnel Description” MIB field (RFC 3812: mplsTunnelDescr) now returns the “LSPName (PathName) on the Ingress node.

Note
The tunnel description is not signaled as part of RSVP messaging, so this information is not available at transit and egress nodes.
Add MPLS (including RSVP-TE) debug information to show tech-support mpls command.
Add support for the Metaswitch dmptrace facility
