Section VIII: Port Security 563
The menu displays the current security level on the selected port. If
you are configuring a range of ports and the ports have different
security levels, the menu displays the security level of the lowest
number port.
Note
Option D, Select Default Port Security, sets the security mode for the
port to the default value of Automatic.
5. From the Configure Port Security menu, type 1 to select Security
Mode.
The following prompt is displayed:
Enter new mode (A-Automatic, L-Limited, S-Secured, K-
locKed):
6. Select the desired security level.
ˆ automatic - Disables security on the port. This is the default setting.
ˆ limited - Sets the port to the Limited security mode. The port learns
a limited number of dynamic MAC addresses.
ˆ secured - Sets the port to the Secured security mode. The port
accepts frames based on static MAC addresses. You must enter
the static MAC addresses of the nodes with frames the port is to
accept after you have activated this security mode on a port.
ˆ locked - Sets the switch to the Locked security mode. The port
stops learning new dynamic MAC addresses. The port forwards
frames based on static MAC addresses and those dynamic
addresses it has already learned.
7. Do one of the following:
ˆ If you selected Automatic, which disables port security on the port,
no further steps are required. Return to the Main Menu to save
your change.
ˆ If you selected the Secure security level, remember to enter the
static MAC addresses of the end nodes that can send packets
through the port. For instructions on how to add static MAC
addresses, refer to “Adding Static Unicast and Multicast MAC
Addresses” on page 110.
ˆ If you selected Locked, no further steps are required. Return to the
Main Menu to save your change. You can, if desired, add static
addresses to a port operating in the Locked security mode. For
instructions, refer to “Adding Static Unicast and Multicast MAC
Addresses” on page 110.
