4.3 Link Pass Through
Link Pass Through is a function that monitors the status of a link for a specified port and notifies the device connected to a port
(to which a link status notification is sent) of the link status of a monitored port by synchronizing the monitored port with the link
status of that port.
This function allows the XG700 to notify the port to which link status notification is sent of a link fault if it is detected in a
monitored port. Link pass through indicates the link fault status to the other port by sending a remote fault (RF) signal, as
prescribed in IEEE802.3ae LFS (Link Fault Signaling). When the link status of the monitored port is restored to normal, the
other port is also restored to normal, the network line having been recovered.
To configure Link Pass Through, carry out the following procedure in the administrator EXEC mode.
Command
Task
xg# configure terminal
Switch to global configuration mode.
xg(config)# link-pass-through { monitored-port
<1-12> | monitored-agg-port <1-6>}
[domino-port <1-12> [<1-12> ]]
[domino-agg-port <1-6> [<1-6> ]]
Set the relationship between the ports to be monitored
and ports to which link status notification is sent.
xg(config)# exit
Exit to administrator EXEC mode.
