It's ugly, but you could also use Embedded Event Manager if you're on a
platform that supports it. Trigger on link up to wait X time, and then do a 'no
neighbor shut' on the peer, and do a 'neighbor shut> immediately upon
link down...

the mac is 6509-b and pps==20/minute is probably HSRP

The root bridge is 6509-a.
The one that is showing these log errors.

Hi James,
I have actually recently created this situation when I setup a 2651 router
to bridge vlan's. Our provider delivers vlans a,b,c,d,e on a trunk port
that I put through a router configured for irb, this caused the mac's on any
vlan to start jumping around on interfaces on their network.

Alan,
Po1 is the connection from 6509-a to 6509-b.
G1/7 goes to port G1/1 on 4506-a.
G1/8 goes to G1/1 on 4506-b.
As for them creating a loop locally, If I disable one of the ports facing them,
the errors persist. Them having a loop in their switch, if it only has a
single connection to my n

ah yes - have you traced the path that these routes take - portchannel goes
to where, Gi1/7 goes where? could they have introduced a loop locally

Actually we want to increase the sampling interval on the collector to
see what's happening on a particular link. I don't know what is the
default sampling interval but we want to change it to something like
every minute.
Thanks David.

I didn't know sampling was available for this platform?
I don't believe it is.
Are you doing this to reduce load / storage on your collector?

Is anyone here using "QoS Bandwidth Estimation"?
I just ask it because I think it could be useful for our network here
but I don't see clear how it works and I would like to share some dudes

Guys,
I am trying to configure Netflow sampling interval on a c1801 router
(IOS version "c180x-broadband-mz.124-15.T6.bin"). I was able to enable
Netflow globally and configured it on the interface as well. But I can't
setup sampling, it doesn't like the commands. What am I doing wrong?
