Operational Binding
When you configure the first tracked port, operational binding is automatically in effect. When you use
this method, you have the option to monitor multiple ports or monitor ports in one VSAN.
To operationally bind a tracked port, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface fc8/6
switch(config-if)#
Step 3
switch(config-if)# port-track
interface port-channel 1
switch(config-if)# no port-track
interface port-channel 1
Tracking Multiple Ports
You can control the operational state of the linked port based on the operational states of multiple tracked
ports. When more than one tracked port is associated with a linked port, the operational state of the
linked port will be set to down only if all the associated tracked ports are down. Even if one tracked port
is up, the linked port will stay up.
