Limiting the Number of MAC Addresses per Port
In NetVisor OS you can limit the number of MAC addresses learned on a per port basis. You can configure this capability (sometimes referred to as port security) on ports or trunks, for example like so:
CLI (network-admin@switch) > mac-limit-modify port 45,49 mac-limit 5 mac-limit-action log
The configuration options for the command are:
CLI (network-admin@switch) > mac-limit-modify
|
port port-list |
Specify the port list. |
|
mac-limit mac-limit-number |
Specify the number of MAC addresses to limit on the port. |
|
mac-limit-action log|disable |
Specify the action to take when the MAC address limit is exceeded. If you select log, an event is logged to the event log. If you specify disable, the event is logged and the port is disabled. |
To display the MAC limits, you can use:
CLI (network-admin@switch) > mac-limit-show
|
port port-list |
Displays the port list. |
|
mac-limit mac-limit-number |
Displays the number of MAC addresses to limit on the port. |
|
mac-limit-action log|disable |
Displays the action taken when the MAC address limit is exceeded. |
|
num-macs num-macs-number |
Displays the number of MAC addresses learned on the port. |
CLI (network-admin@switch) > mac-limit-show
port mac-limit mac-limit-action num-macs
