Configuring and Monitoring Port Security
Port Security
Adding an Authorized Device to a Port. To simply add a device (MAC
address) to a port’s existing Authorized Addresses list, enter the port number
with the mac-address parameter and the device’s MAC address. This assumes
that Learn Mode is set to static and the Authorized Addresses list is not full
(as determined by the current Address Limit value). For example, suppose
port A1 allows two authorized devices, but has only one device in its Autho-
rized Address list:
The Address Limit has not
been reached.
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.
Figure 13-6. 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.
ProCurve(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.
