3548 GBIC Stack

Hello everyone,

We've 5 Nos of 3548 switches on our Network stacked together using GBIC stack. One of the Switch is connected with core Switch (6509 ) .We have enabled the Full duplex on the switch which is connected with core switch and rest of the stacked switches are in half duplex on GBIC port. When , we wanted to enable Full duplex on stacked switches as well , the Network consultant said that Cisco recommends to keep the stacked switches in half duplex mode . Is it true ?. pls confirm...

Re: 3548 GBIC Stack

The stack is a BUS medium and not point-to-point connections. If there are more than 2 switches in the stack, half-duplex configuration is required.
