You cannot disable MAC address learning on an RSPAN VLAN. The configuration is not allowed.

If you disable MAC address learning on a VLAN that includes a secure port, MAC address learning is 
not disabled on the secure port. If you later disable port security on the interface, the disabled MAC 
address learning state is enabled.

To display MAC address learning status of all VLANs or a specified VLAN, enter the show 
mac-address-table learning [vlan vlan-id command].

This example shows how to disable MAC address learning on VLAN 2003:

Switch(config)# no mac address-table learning vlan 2003

To display MAC address learning status of all VLANs or a specified VLAN, enter the show mac 
address-table learning [vlan vlan-id] command.

Displays the MAC address learning status on all VLANs or 
on the specified VLAN.
