Monitoring Layer 2 Services over MPLS

This chapter describes the commands you can use to monitor and troubleshoot layer

2 services over MPLS on E Series routers.

NOTE: The E120 and E320 Broadband Services Routers output for monitor and show

commands is identical to output from other E Series routers, except that the E120

and E320 router output also includes information about the adapter identifier in the

interface specifier (slot/adapter/port).

This chapter contains the following sections:

■ Setting Baselines for Layer 2 Services over MPLS Statistics on page 563

■ Monitoring ATM Martini Cell Packing Timers for Layer 2 Services over

MPLS on page 564

■ Monitoring ATM Subinterfaces for Layer 2 Services over MPLS on page 564

■ Monitoring ATM Cross-Connects for Layer 2 Services over MPLS on page 566

■ Monitoring MPLS Forwarding for Layer 2 Services over MPLS on page 567

■ Monitoring MPLS Layer 2 Interfaces for Layer 2 Services over MPLS on page 568

Setting Baselines for Layer 2 Services over MPLS Statistics

You can set a baseline for the statistics for all MPLS major interface statistics on the

specified interface with the baseline mpls interface command. The router implements

the baseline by reading and storing the statistics at the time the baseline is set and

then subtracting this baseline when you retrieve baseline-relative statistics.

Use the delta keyword with the show mpls commands to display baselined statistics.

The following statistics are maintained for each MPLS shim interface:

■

transmit packets and

octets

■

receive packets and

octets

■

transmit discarded

packets

■

receive discarded packets

■

transmit error packets

■

receive error packets
