Description
Port security prevents unauthorized access of a port by “securing” a list of
specific MAC addresses to a port. If the switch sees a MAC address that is
not on the secured list, it discards the packet.
To set port security from Local Management
1 On the Configure Device screen, select Forwarding and Filtering.
2 Select Configure Port Security.
3 Select a port you want to secure. Press z in the Learning field to
disable the port’s ability to learn new MAC addresses.
4 Press q to move up a level, and then select the Configure Static
MAC Addresses screen.
5 Define a list of MAC addresses and assign them to the same port you
secured in the Port Security screen.
To turn off port security
1 On the Configure Device screen, select Forwarding and Filtering. Select
Configure Port Security.
2 Select the port on which you want to disable security. Press z in
the Learning field to disable security and enable the port to learn new
MAC addresses.
NOTE
You must first configure port
security before configuring a
static MAC address.
If you locked the address table on
the Forwarding and Filtering
screen, you must return to the
screen and unlock the table
before making changes on the
Port Security screen.
