I think he was asking about the Switched Port Analyzer (SPAN) feature that
allows one to connect a protocol analyzer or RMON probe or other device to
one switch port and monitor other ports. This is a switch feature,
It all looks so obvious now:
Switch-A(config)#interface fastEthernet 3/1
Switch-A(config-if)#switchport
Switch-A(config-if)#switchport access vlan 1
Doh...Doh...Doh !
Thought BVI's seemed a bit long winded.
I'm embarrassed!

Doh!
I upgraded a 6000 a few months ago to have a quick play, but had to
downgrade it shortly after for an install.
I presume from your post that I may have been creating switched ports the
long way?
Creating BVI's is probably the long way.

I believe you are correct. I misunderstood. Although I've connected a
laptop to a monitor (span) port before without using the inpkts command, and
I was able to use the laptop on the network as well as hear any traffic from
the other port(s).

I'm not totally positive because I have never used the inpkts switch on a
monitor command...but I think he might have been referring to the sniffer
being able to send packets out... (say you are using a sniffer, not in
promiscuous mode, and you want to be able to do reverse lookups on ip
addresses
We've setup span ports to monitor servers, etc and we never had to issue any
extra commands so that layer 3 (IP) worked properly. I'm "monitoring" a port
right now and the server attached to the port I'm s "monitoring" operates
just fine, IP broadcasts, ping, etc

Not yet. So far the Native IOS has been a supereme OS. You can make
switchports for the ports you want to be switchports, but it's IOS for the
rest. It's nice to have the entire switch under IOS control.

If you want to allow the attached device to ping or browse, be it an IDS or
pc, you need to add the "inpkts" cmd when setting up any span or rspan
session.

One more stab from the limb I've gotten myself onto.
Can you tell us more about your setup? What is it that you think is going
to send a session reset? Are you using Cisco Secure Policy

Actually what is going on is we are trying to get the port span feature

Here's an interesting twist to that question: If your switch/router is a
6500 running Native IOS, can you span ports that are configured as router
interfaces as opposed to switchports?

Steven,
STP is a layer 2 only function and in general it is configured only on
switches. It can be configured on a router if the router is configured to
act as a transparent bridge. More info can be found on Cisco's web
I believe it's just switch function. If I'm wrong, someone will correct me,
but I'm 99.9% sure.
