After an NE40 on the live network was reset, MPLS LSPs failed to be created for some connected devices, resulting in service interruption.
The log information on the NE40 was as follows:#May 18 19:18:55 2012 CC-R-3 TNLM/4/TRAP:
Huawei performed the following operations to address the problem:
1. Checked the token specifications for establishing MPLS LSPs for 32-bit addresses.
The token resources allowed establishment of a maximum of 1000 LSPs.
<CC-R-3>display tunnel-info statistics
Tunnel Allocation Method : MIXED-2GLOBAL
Seperation point b/w Global and PerSlot 2000
Seperation point b/w Global Space 1000 //This global space indicated the token resources for establishing MPLS LSPs for 32-bit addresses
Max Tunnel ID Value Per Board 10000
Total Tunnel ID Allocated 1099
2. Ran display mpls lsp to query the number LSPs on the current NE40E.The NE40E had more than 1000 LSPs.
