To disable port security on a port, run the net del interface port-security command. The following example commands put swp1 into ADMIN down state when there is a security violation and set the timeout value to 3600 seconds: net add interface swp1 port-security violation net add interface swp1 port-security violation timeout net net commitĪfter you configure the port security settings to suit your needs, you can enable security on a port with the following commands: net add interface swp1 net net commit You can also set a timeout value between seconds for the action to take effect. When packets are dropped, Cumulus Linux sends a log message. shutdown puts a port into ADMIN down state.You can configure the action you want to take when there is a security violation on a port: The example commands configure swp1 to limit access to 40 MAC addresses: net add interface swp1 port-security mac-limit net net commit You can specify a number between 0 and 512. To limit the number of MAC addresses that are allowed to access a port, run the following commands. net add interface swp1 port-security net add interface swp1 port-security sticky-mac timeout net add interface swp1 port-security sticky-mac net net commit The example commands enable sticky MAC on interface swp1, set the timeout value to 2000 seconds, and enable aging. The default aging timeout value is 1800 seconds. You can add a timeout value so that after the time specified, the MAC address ages out and no longer has access to the port. To enable sticky MAC on a port, where the first learned MAC address on the port is the only MAC address allowed, run the following commands. See Configure Port Security Manually below. To specify multiple MAC addresses, set the interface.port_security.static_mac parameter in the /etc/cumulus/switchd.d/port_nf file. You can specify only one MAC address with the NCLU command. The example commands configure swp1 to allow access to MAC address 00:02:00:00:00:05: net add interface swp1 port-security allowed-mac 00:02:00:00:00:05 To limit port access to a specific MAC address, run the following commands. However, interfaces in a bond are not supported. Layer 2 interfaces in trunk or access mode are currently supported.Port security is supported only on Broadcom switches.

You can specify what action to take when there is a port security violation (drop packets or put the port into ADMIN down state) and add a timeout for the action to take effect. Limit port access to a specific number of MAC addresses.You can provide a timeout so that the MAC address on that port no longer has access after a specified time.

Limit port access to only the first learned MAC address on the port (sticky MAC) so that the device with that MAC address has full bandwidth.

Limit port access to specific MAC addresses so that the port does not forward ingress traffic from source addresses that are not defined.

Port security is a layer 2 traffic control feature that enables you to manage network access from end-users.
