Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
BERT is supported on each of the T3/E3 or T1/E1 links. It is done only over an unframed T3/E3 or T1/E1
signal and is run on only one port at a time. It is also supported on an individual channel group.
To begin a BERT, commit the configuration and use the bert t1, bert e1, bert t3, or bert e3 command in
EXEC mode.
To view the BERT results, use the show controllers t1 or show controllers t3 command in EXEC mode.
The BERT results include the following information:
• Type of test pattern selected
• Status of the test
