Cisco SX350 mac learning per VLAN

Hi all,

 

Looking for some advice on port security & mac address learning. Essentially we are looking to lock down connections on a particular VLAN running on our Cisco SX350 switch. I have toyed around with ACL which seem to work but are little sensitive when editing.

 

I have added a sticky mac address (the authenticated device) to the port on the native VLAN, I now need to know how to block mac address learning on the port. The catch is that there is a tagged VLAN on the port which does require learning.

 

Is there any way to disable learning on the native or a single VLAN only? 

 

Thanks,

 

Jonathan

How about .. 

 

no mac-address-table learning { vlan vlan-id [ , vlan-id | -vlan-id] | interface interface slot / port }

Disable MAC address learning on an interface or on a specified VLAN or VLANs.

You can specify a single VLAN ID or a range of VLAN IDs separated by a hyphen or comma. Valid VLAN IDs 1 to 4094. It cannot be an internal VLAN.

Thanks for the replies. These seem to relate to the Catalyst switches. We are using the small business Cisco SX350 series. CLI slightly different.
