When an admin>reboot command is issued, routers with redundant CPM are rebooted as well as the XMAs, XCMs, and IOMs. Changes are lost unless the configuration is saved. Use the admin>save file-url command to save the current configuration. If no command line options are specified, the user is prompted to confirm the reboot operation.

Use the following CLI syntax to reboot:

admin reboot [active | standby | upgrade] [hold] [now]
A:ALA-1>admin# reboot
