You have the right idea with STP, setting the port priority should allow you to control which port goes into the blocking state. So in this case we could set the RF link to be in the blocking state. Here are some links with some good information on this. www.dell.com/.../app_note_13.pdf www.dell.com/.../pwcnt_MSTP_interoperability.pdf support.dell.com/.../cli_en.pdf www.dell.com/.../app_note_1.pdf The following example configures the spanning priority on 1/g5 to 96. console(config)#interface ethernet 1/g5 console(config-if-1/g5)#spanning-tree port-priority 96 Keep us updated. Thanks
Hi all, I am fairly new to setting up switches and need some advice on how to configure links between switches. I have a flat layer 2 network in building 1 with a 6248 switch acting as a core switch and a 6224 in building 2. The two buildings are connected together via a 1GB laser link and a 100MB RF link; the laser is the primary link and is plugged in all the time in building 1, the cable for the RF link is left unplugged. In building 2 both cables are plugged in. When the laser link fails (thick fog and snow !) we have to manually unplug the laser in building 1 and plug in the RF link. I would like to configure the switches to automatically fail between the links without having to manually plug in cables. I assume this is done using STP but I am not sure how to configure this to avoid a routing loop - any help would be greatly appreciated.   Thanks,
inter switch connection
