Well, you'll need to move the "int Vlan1" config of course. You say you're on a "Cisco devices" network, but it's worth mentioning anyway... One weirdie about Cisco VLAN1 is that, using PVST, the instance that runs in VLAN number 1 (and vlan number 1 ONLY) emits both 802.1d/w PDUs and PVST PDUs and therefore will interact with non-PVST devices. Can be useful or horrible. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
