request chassis sfm master switch
Syntax
request chassis sfm master switch <no-confirm>
Description
(M40e and M160 routers only) Control which Switching and Forwarding Module (SFM) is primary.
Options
| no-confirm | (Optional) Do not display a switch warning or query. |
Additional Information
By default, the SFM in slot 0 (SFM0)
is the primary and the SFM in slot 1 (SFM1) is the backup. If you
use this command to change the primary, and then restart the chassis
software for any reason, the primary reverts to the default setting.
To change the default primary SFM, include the sfm statement
at the [edit chassis redundancy] hierarchy level in the
configuration. For more information, see the Junos OS Administration Library for Routing Devices.
All installed SFMs are always working together to forward packets. If an SFM fails, the other SFMs take over and traffic continues to flow uninterrupted.
Required Privilege Level
