request chassis feb

Syntax

Syntax (ACX7509 Router)

Description

Offline, online, restart the specified FEB. Upon restart, the FEB goes offline and online within the stipulated time. FEB traffic is forwarded before power off. Traffic is recovered after FEB is online.

On ACX7509 routers, when a primary FEB is made offline or restarted, the switchover to backup FEB does not take place. This results in traffic loss as none of the FEB is forwarding the traffic. If you make the primary FEB offline or restart it, a traffic loss warning message is displayed and the request is rejected. You can use the force option to forcefully offline or restart the primary FEB.
