    Switch SFM Mastership

    To switch SFM mastership on M40e routers only. By default, the SFM in slot 0 (SFM0) is the master and the SFM in slot 1 (SFM1) is the backup.

    To change the default master SFM, include the sfm statement at the [edit chassis redundancy] hierarchy level in the configuration. For more information, see the Junos OS System Basics Configuration Guide.

    To switch SFM mastership, use the following command:

    user@host> request chassis sfm master switch <no-confirm>

    Sample Output

    user@host> request chassis sfm master switch
    warning: Traffic will be interrupted while the PFE is re-initialized
    Toggle mastership between system forwarding module? [yes,no] (no) yes
    Switch initiated, use “ show chassis sfm”  to verify
    

    The following command output displays if you use the no-confirm option:

    user@host> request chassis sfm master switch no-confirm
    Switch initiated, use “ show chassis sfm”  to verify
