Configuring and Monitoring Port Security

Port Security Command Options and Operation

Although the Address Limit is set to 2, only one device has been authorized for this port. In this case you can add another without having to also increase the Address Limit.

The Address Limit has not been reached.

Figure 7-4. Example of Adding an Authorized Device to a Port

With the above configuration for port A1, the following command adds the 0c0090-456456 MAC address as the second authorized address.

HPswitch(config)# port-security a1 mac-address 0c0090- 456456

After executing the above command, the security configuration for port A1 would be:

The Address Limit has been reached.

Figure 7-5. Example of Adding a Second Authorized Device to a Port

(The message Inconsistent value appears if the new MAC address exceeds the current Address Limit or specifies a device that is already on the list. Note that if you change a port from static to continuous learn mode, the port retains in memory any authorized addresses it had while in static mode. If you subsequently attempt to convert the port back to static mode with the same authorized address(es), the Inconsistent value message appears because the port already has the address(es) in its “Authorized” list.)
