From: dkoppisetti@xxxxxxxxxxx To: shemminger@xxxxxxxx Subject: Selecting a Root port on a bridge Date: Tue, 10 Mar 2009 22:29:38 -0400 Hi, i have setup a bridge which has 5 ethernet ports. 2 of the ethernet ports are on board and 3 are on add boards. The 2 ports on the ethernet PMC are eth0 and eth1. The onboard ethernet ports are eth2 and eth3. There is a FPGA on the board that has the other ethernet port. I would like the root port of the bridge to be eth2 instead of eth0. Is there a way to set it up. I am using the following script from http://www.faqs.org/docs/Linux-HOWTO/BRIDGE-STP-HOWTO.html When I enter ifconfig the bridge shows an ip address of 192.168.100.5 the mac address listed is the address of eth0. What I need is to have the ip address listed on the mac address that is on eth2. Please let me know if there is a way. #! /bin/bash # Copyright (c) 2000 Uwe Böhme.
