Yes, you can use "speed auto 100 1000". Beware of the challenges regarding buffering on the platform -- a thing that becomes much more relevant when running the ports at less than 1 Gb/s. You could also use "srr-queue bandwidth limit 10" to limit the bandwidth, though this only works for outbound traffic and cannot limit the port to anything less than 10%. > Second, is there any way with a switch like this to alter the port > number? > > instead of GigabitEthernet0/1 it would be GigabitEthernet1/1?

The closest thing that comes to mind is "define interface-range", but it has to be accessed with "interface range macro <name>" so that's probably not really useful. And the "alias" command cannot usefully include whitespace. The 3750 interfaces are named "GigabitEthernet1/0/1" and forward by the way. First numeric ID is the switch number in the stack, or 1 for a stand-alone switch. It's better to fix the software. :-) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
