I have a question on how this works.
switch(config)#vlan access-map CISCO
<----- This sets the map name to Cisco
switch(config-access-map)#match ip address dog
<------ This sets the map to match the ACL named dog
<------ This forwards whatever is matched in the ACL above
switch(config)#vlan filter CISCO vlan-list 10-20
Now I'm not sure what happens. It applies the filter to Vlans 10-20 and does this mean it will only allow traffic that matches the ACL both in and out of the Vlans or just in or just out.
I understand it will drop what it doesn't match but how is it applied?
Can someone post a real world scenario where you would use a vlan map and what it would look like?
