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.
When the line is placed in administrative shutdown state, use the ais-shut command to send a signal to
downstream equipment that indicates that there is a problem with the line.
The ais-shut command is ignored if automatic protection switching (APS) is running for the corresponding
port, because the setting must be enabled for proper APS operation.
For SONET ports that do not have hardware support for LAIS insertion, the ais-shut command is disabled.
