Re: UNI and NNI

Just to add to what Steve said ..... it is always a good idea to go through
the doc of any ME switch to understand how defaults work from this Metro E
switch ..

I am saying so because the behavior is very diff from a standard CAT based
switch ..

For example you will have 2 ports in same vlan not talking to each other
..... finally you will discover that that's how a UNI port is supposed to
behave ..

So from a certification point of view ; I believe that this concept should
have been played with before seeing surprises in actual lab :))

Thnx
