I have a few questions relating to smartport roles and with which one is correct for specific trunk links.
1. Should I modify the 2 x trunk ports between each of the 3750G Core/Dist switches?
and if so, what role will I give them, Switch or Router? (as both 3750G's cores are running L2 and L3)
2.For Trunk ports assigned to specific vlans on the 2 x 3750G's(cores), I believe these should be assigned the role of a switch, but should I select Vlan 1(default) as the Native Vlan
3. Why use smartports, what are the benefits ?
is there any point in using Smartports on them aswell?
I personally have never used Smartports and I've configured thousands of switches.
If you want to know what's in the Smartport macro, you can type the command sh parser macro and observe the syntax.
