Chapter 4
Monitoring MPLS
This chapter describes the commands you can use to monitor and troubleshoot
Multiprotocol Label Switching (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).
