request chassis feb
Syntax
request chassis feb slot slot-number (offline | online | restart)
Syntax (ACX7509 Router)
request chassis feb slot slot-number (offline | online | restart) <force>
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.
Options

|
| online |
Bring the specified FEB online. |
|

user@host> request chassis feb restart slot 1 warning: RCB and FEB work in the paired slot mode. FEB 1 offline/restart will result in traffic loss and does not cause a switchover. Please re-try after initiating a mastership switchover using 'request chassis routing-engine master switch' CLI. If offline/restart is still intended, use 'force' option in addition to this CLI.
