Monitoring Interfaces
From User Exec mode, use the following show commands to monitor and display
the T3 interface, T1 interface, and HDLC serial data channel information:
■
Monitor channelized T3 interfaces on a slot and port.
host1# show controllers t3 0/1
■
Monitor a T1 interface.
host1# show controllers t3 0/1:1
■
Monitor fractional T1 subchannels.
host1# show controllers t3 ft1
■
Monitor the state of the serial interface or a slot/port.
host1# show controllers t3 serial 0/1
Setting a Baseline
You can set a statistics baseline for serial interfaces, subinterfaces, and/or circuits
using the
baseline interface serial command. Use the delta keyword with the show
commands to display statistics with the baseline subtracted.
Displaying Counters and Time Intervals
Counters and time intervals are MIB statistics, which are defined in the following
specifications:
■
