We'd like to eliminate our (2600) router currently connecting a layer-2 (DEC) network to our Cisco (layer-3) net, by using one of the FastEthernet ports on our Cat6509 6548 cards??1- Don't want stp between DEC/Cisco nets.Can we shut off stp on the FE...

What does the 3548 default to on FE ports if not set?auto-negotiation?

Cant the PIX firewall be configured w/out NAT?

We have an LRE (LongReachEthernet) port that keeps bouncing up and down. We have verified that the remote end (2950 switch) speed/duplex match the LRE Ethernet feed port speed/duplex. (10M/Half)show controllers lre status link:RS Errs - 0AGC-Gain - 2...

We are getting CDP error msgs. complaining that we have full duplex on one switch and half on another.I'm not sure if no cdp enable will clear up. (will try) What I'm wondering, is what's "wrong" with mixing full and half on switches?
