VLAN Filtering for Non-IP Traffic
The task is asking to allow only STP BPDUs, CDP, VTP, UDLD and ARP protocols using VLAN filter.
The solution provided for this task is:
SW1: mac access-list extended ALLOWED_L2_TRAFFIC permit any any lsap 0x4242 0x0 permit any any 0x010B 0x0 permit any any 0x806 0x0 ! vlan access-map VLAN10_FILTER 10 match mac address ALLOWED_L2_TRAFFIC action forward !
vlan filter VLAN10_FILTER vlan-list 10
Can someone please explain to me which part of this solution allows CDP, VTP and UDLD protocols?
