Setting port security's limit on the number of MAC addresses on a port
You can set the maximum number of MAC addresses that port security allows on a port for the following purposes:
Controlling the number of concurrent users on the port. The maximum number of concurrent users on the port equals this limit or the limit of the authentication mode (802.1X for example) in use, whichever is smaller.
Controlling the number of secure MAC addresses on the port in autoLearn mode.
The port security's limit on the number of MAC addresses on a port is independent of the MAC learning limit described in MAC address table configuration in the Layer 2—LAN Switching Configuration Guide.
To set the maximum number of secure MAC addresses allowed on a port:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter Layer 2 Ethernet interface view. | interface interface-type interface-number | N/A |
3. Set the limit of port security on the number of MAC addresses. | port-security max-mac-count count-value | Not limited by default. |
