(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 subse-
quently 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 1 allows one authorized device and
already has a device listed:
HP Switch(config)# show port-security 1
Port Security
Port : 1
Learn Mode [Continuous] : StaticAddress Limit [1] : 1
Action [None] : None
Eavesdrop Prevention [Enabled] : Enabled
