loopback
•
Use to configure a loopback.
•
Specify one of the following loopback options:
•
local —Loops the data back toward the router; on supported line modules, also sends
an alarm indication signal (AIS) out toward the network
•
network —Loops the data toward the network before the framer processes the data
•
payload —Loops the data toward the network after the framer processes the data
•
remote —Sends a far end alarm code in the C-bit framing, as defined in ANSI T1.404,
to notify the remote end to activate or (when you use the no version) deactivate the
line loopback
NOTE: Remote loopback is available only on frame-based T3 interfaces configured to
use C-bit framing.
•
Example
host1(config-controll)# loopback local
•
Use the no version to restore the default configuration, no loopback.
•
See loopback.
Monitoring Interfaces
From User Exec mode, use the following show commands to monitor and display the
T3 or E3 interface information:
host1# show controllers t3 0/1
host1# show controllers e3 3/2
Setting a Baseline
You can set a statistics baseline for serial interfaces using the baseline interface serial
command. Use the delta keyword with the show commands to display statistics with
the baseline subtracted.
