Interface Configuration Commands
For SONET performance, the system monitors the B1 byte, which is used to compute the four SONET
section layer performance monitor parameters:
•SEFS-S (section severely errored framing seconds)
•CV-S (section code violations)
•ES-S (section errored seconds)
•SES-S (section severely errored seconds)
Note Before monitoring can be enabled, you must configure protocol encapsulation for the interface using
the encapsulation command.
Monitoring signal error statistics is useful for isolating system and network faults.
Examples The following example shows how to monitor error counters on a transparent interface.
Switch# configure terminal
Switch(config)# interface transparent 2/0/0
Switch(config-if)# monitor enable
