Configuring Port Tracking
If tracking is established, you see Success in the lower left corner of the dialog box as shown in
Figure 27-5.
Figure 27-5 Successful Port Tracking Established
Step 10 Click Close to close the dialog box.
The following example shows how to enable port tracking for specific interfaces:
switch# configure
switch(config)# interface fc 2/4
switch(config-if)# port-track interface san-port-channel 2
About 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.
In Figure 27-6, only if both ISLs 2 and 3 fail, will the direct link 1 be brought down. Direct link 1 will
not be brought down if either 2 or 3 are still functioning as desired.
