Troubleshooting Tips
• Link down is the superset of all other causes. A port is brought to down state if the total number of
other causes equals to the number of allowed link-down failures.
• Even if the link does not flap due to failure of the link, and port guard is not enabled, the port goes
into a down state if too many invalid FLOGI requests are received from the same host. Use the shut
and the no shut commands consecutively to bring up the link.
Configuring Port Monitor
This section includes the following topics:
• Enabling Port Monitor, page 2-31
• Configuring a Port Monitor Policy, page 2-32
• Activating a Port Monitor Policy, page 2-34
Enabling Port Monitor
Detailed Steps
To enable port monitor, follow these steps:
Command Purpose
Step 1
switch# config t
Enters configuration mode.
Step 2
switch(config)# port-monitor enable
Enables (default) port monitoring.
switch(config)# no port-monitor enable
Disables port monitoring.
