Configuring and Monitoring Port Security

Port Security

(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.)

If you are adding a device (MAC address) to a port on which the Authorized Addresses list is already full (as controlled by the port’s current Address Limit setting), then you must increase the Address Limit in order to add the device, even if you want to replace one device with another. Using the CLI, you can simultaneously increase the limit and add the MAC address with a single command. For example, suppose port A1 allows one authorized device and already has a device listed:

Figure 11-7. Example of Port Security on Port A1 with an Address Limit of “1”

To add a second authorized device to port A1, execute a port-securitycommand for port A1 that raises the address limit to 2 and specifies the additional device’s MAC address. For example:

ProCurve(config)# port-security a1 mac-address 0c0090- 456456 address-limit 2
