Unanswered Question
Jun 9th, 2009

Hi,

Has any one configured sub-Interfaces on 3750 or 3660 switches. I see the command is there, but the switch will not take the command. Here is the part number for one of the 3560s

WS-C3560G-48TS-S

Thanks,

Reza

I have this problem too.

Hello Reza,

on a multilayer switch you should use:

a L2 trunk carrying all required vlans

+

SVI L3 vlan interfaces for each L2 vlan on the trunk

Vlan based subinterfaces are used on routers interfaces

Hope to help

Giuseppe
