How to Configure MPLS Transport Profile
Priority of Inputs
The event priority scheme for locally generated events is as follows in high to low order:
Local Events:
1. Opr-Clear (Operator Clear)
2. LoP (Lockout of Protection)
3. LoP'/LoP'-Clear
4. FS (Forced Switch)
5. FS'/FS'-Clear
6. MS (Manual-Switch)
The emLockout received on the working LSP is mapped to the local-FS'. The emLockout received on the
protected LSP is mapped to the local-LoP'. The emLockout-clear received is mapped to the corresponding
clear events.
The priority definition for Signal Fail (SF), Signal Degrade (SD), Manual Switch (MS), WTR, Do Not Revert
(DNR), and No Request (NR) remains unchanged.
PSC Syslogs
The following are the new syslogs that are introduced as part of the Linear Protection with PSC Support
feature:
SYSLOG NAME
MPLS_TP_TUNNEL_PSC_PREEMPTION
MPLS_TP_TUNNEL_PSC_TYPE_MISMATCH
How to Configure MPLS Transport Profile
Configuring the MPLS Label Range
You must specify a static range of Multiprotocol Label Switching (MPLS) labels using the mpls label range
command with the static keyword.
