Port Security (mac address whitelist) on Port Channel

[mr-butcher]

A customer wants to secure the uplink port which is a port channel. So can I add a mac address whitelist on a port-channel? I didn't find the corresponding option in the port-channel settings.

No, MAc whitelisting is only available on access ports. I'm assuming your uplink is a trunk.

[mr-butcher]

Yes it's a trunk. Thank you for your answer

He can do restriction with "Allowed VLAN´s" on the Uplink trunk ports. This filters all MAC-addresses from other VLANS.

We do this anyway. But the customer want's to prevent users from using the uplink cable of the mini switch to plug in a not whitelisted device.

The switch is not locked in a rack or similar.
