Syntax

content_copy zoom_out_map
request chassis feb slot slot-number (offline | online | restart)

Syntax (ACX7509 Router)

content_copy zoom_out_map
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

slot slot-number

FEB slot number. Replace slot-number with the FEB slot number value of your platform.

offline

Bring the specified FEB offline.

online

Bring the specified FEB online.

restart

Restart the specified FEB.

force Force execute the offline/restart command. Only available for ACX7509 routers.

Required Privilege Level

maintenance

Output Fields

When you enter this command, you are provided feedback on the status of your request.

Sample Output

request chassis feb (ACX1000 Router)

content_copy zoom_out_map
user@host> request chassis feb slot 0 restart 
FEB will be restarted NOW.

request chassis feb (ACX7509 Router) (Primary FEB)

Note:

Slot 1 is the primary FEB for the example commands provided below.

content_copy zoom_out_map
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.
content_copy zoom_out_map
user@host> request chassis feb offline 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.

If offline/restart is still intended for primary FEB, use force option in addition to the command. For example:

content_copy zoom_out_map
user@host> request chassis feb offline slot 1 force 
Offline initiated, use "show chassis feb" to verify

request chassis feb (QFX5700 Switch)

content_copy zoom_out_map
user@host> request chassis feb slot 0 online 
Online initiated, use "show chassis feb" to verify
