IXP MPLS Enhancements
Release 15.4 adds the following IXP MPLS
- EMS logs reflect the operation status changes of LSPs, PWs, and
- 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”).
MPLS Protocol Interfaces
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
- Use RSVP-TE “Tunnel Description” field in MPLS TE MIB to indicate LSP
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
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
