Uplink Failure Detection (SMUX mode)
In Standalone or VLT modes, by default, all the server-facing ports are tracked by the operational status
of the uplink LAG. If the uplink LAG goes down, the aggregator loses its connectivity and is no longer
operational. All the server-facing ports are brought down after the specified defer-timer interval, which is
10 seconds by default. If you have configured VLAN, you can reduce the defer time by changing the
defer-timer value or remove it by using the
no defer-timer command.
