VLAN MAC Locking
Use the VLAN MAC Locking Status page to configure VLAN MAC Locking. VLAN MAC locking allows
you to secure the network by locking down allowable MAC addresses on a given VLAN. Packets with a
matching source MAC address can be forwarded normally. All other packets will be discarded. VLAN
MAC locking will lock the dynamic MAC entries.
If VLAN and port MAC locking are enabled, VLAN MAC locking will be given precedence over port MAC
locking.

Table 243: Port Security Interface Configuration Fields
Field
Description
VLAN ID
The VLAN ID specified in the Ethernet frame received by the interface.
Interface
The interface associated with the rest of the data in the row.
Dynamic MAC Address
The MAC address that was learned on the device. An address is dynamically
learned when a frame arrives on the interface and the source MAC address in the
frame is added to the MAC address table.
Max Dynamic Addresses
Allowed
The number of source MAC addresses that can be dynamically learned on an
interface. If an interface reaches the configured limit, any other addresses
beyond that limit are not learned, and the frames are discarded. Frames with a
source MAC address that has already been learned will be forwarded. A
dynamically-learned MAC address is removed from the MAC address table if the
entry ages out, the link goes down, or the system resets. Note that the behavior
of a dynamically-learned address changes if the sticky mode for the interface is
enabled or the address is converted to a static MAC address.
Operational MAC Limit
The number of source MAC addresses that are dynamically currently reached to
that of Maximum Configured MAC Limit.
Violation Shutdown Mode
After MAC limit has reached, action will shut down the ports participating in the
VLAN.
Violation Trap Mode
After MAC limit has reached, a log message will be generated with violation MAC
address details.
To configure The VLAN MAC Locking, use the following buttons to perform the tasks:
•
Use Submit to enable or disable VLAN MAC Locking Admin Mode.
•
Use Add to configure VLAN MAC Locking.
•
Use Edit to modify configuration parameters of VLAN MAC Locking.
•
Use Remove to remove configured VLANs.
Port Security Statically Configured MAC Addresses
Use the Port Security Static MAC Addresses page to view static MAC addresses configured on an
interface. From this page, you can delete statically configured MAC addresses.
