Cisco Cisco IOS Software Release 12.0(22)S

The benefits described in the following paragraphs are available to you with the MPLS-LSR-MIB.

By monitoring the cross-connect entries and the associated incoming and outgoing segments, you can 
see which labels are installed and how they are being swapped. Use the MPLS-LSR-MIB in place of the 
show mpls forwarding CLI command.

By monitoring interface and packet operations on an MPLS LSR, you can identify high- and low-traffic 
patterns, as well as traffic distributions.

By identifying potentially high-traffic areas, you can set up load sharing to improve network 
performance.

By comparing results from SNMP get commands and the show mpls forwarding CLI command, you 
can verify your LSR configuration.

By monitoring the cross-connect entries and the associated incoming segments and outgoing segments, 
you can determine the active LSPs.
