1. Does mls running only on cat6000,cat5000 and cat4000? How to implement l3 switching on cat3550 if it doesn't support mls?
2.What's difference between mls and cef ? Cat6000 support these functions both.Will cat6000 choose which type of technology when packet come in? cef or mls?
3.In my 6509,mls flow mask is Destination flow and my msfc2 is configured with extented ip access-list. I remember book <lan switching> writened by clark said 6509 will use destination−source flow if there is extented access-list. what's wrong with this?
CAT3550/CAT6000 with Sup2/MSFC2, CAT4000 with Sup3/4 uses CEF based forwarding. CAT6000 with Sup1/MSFC support MLS only
CEF is a enhanced implementation of MLS. With MLS, the first packet hits the router to get routed and then subsequent flows are hardware switched, but with CEF, even the first packet need not be routed by the router.
With access-lists, Source and Destination IP addresses needs to be cached as well. With extended Access-lists, TCP port numbers need to be cached as well(Full Flow). So if you have regular ACLs, the "destination-source flow" will be used and with extended ACLs, Full flow will be used
