BCMSN:Layer 2 switching

waru

Hi,

I am just starting looking at bcmsn and Im reading the David Hucaby Cert guide. In the section on layer 2 switching it mentions that the TCAM contains security ACLS and QoS ACLs. So this means a pure layer 2 switch still has the capacity to make forwarding decisions based on layer 3+ information?

I know this is probably kind of obvious but I just wanted to confirm it!

cheers

I dont think so.. The ACLs and QoS they are talking about would be MAC based.
