Configuration
All configuration commands in the table below should be followed for each switch.
#configure terminal | Enter configure mode. |
(config)#interface xe3 | Enter interface mode. |
(config-if)#switchport | Set switching characteristics on the port. |
(config-if)#ethernet oam enable | Configure EFM on interface |
(config-if)#ethernet oam mode passive | Configure EFM mode Passive. Default is Active |
(config-if)#ethernet oam mode active | Configure EFM mode Active |
(config-if)# ethernet oam remote-loopback start | Configure remote-loopback start |
(config-if)# ethernet oam remote-loopback stop | Configure remote-loopback stop |
(config-if)#commit | Commit the configuration |
(config-if)# exit | Exit from interface mode |
