been told this still happens if theres only one link
to the 4500s to the client - which makes the 6506-b almost

I have a VSS router that I want to do some out-of-band mgmt with. Is
this possible with VRF-lite ? I would like to build a channel with the

this interface out of the standard routing table. Can this be done with
VRF-lite ? Or

But why only 1 MAC is flapping?
HSRP sends dest-mac as multicast address so there are clearly 2 paths
between these switches.
Unless the connection is unidrecional somehow, how on earth he doesn't
see same on second 6509-b?
It's confusing.

Hi Tony,
After disabling QoS there are no longer any output drops. Thanks for the
suggestion.
Are there any features that rely on QoS, or is it a default setting? I'm
trying to figure out something reasonable as to why it was enabled in the
first place.

The most confusing thing is.. The Mac that is flapping is the Mac address for
the vlan interface (VLan 42 of course) from 6509-b. But I am only seeing the
log entries on 6509-a.
I am looking at the entire path of the vlan now. Maybe it is patched into
another vlan at some point that I am
Alan,
You guessed it. The customer had vlan 42 and another vlan tied together in
their switch. That’s where the errors were coming from.
Thanks for all of the ideas.

Hey folks..
Does anyone know how the 7600 chassis (7606) handles power inbalance? To
explain a bit more, we have a pair of 2700Watt DC power supplies in a 7606
that needs to be upgraded soon. To avoid downtime, we are looking at
upgrading one side and then the other. They are running

If you are running a newer IOS and newer ROMMON you can disable
password-recover (i.e. break during boot) using no service password-recovery.
Make sure to read

I can't answer why it was enabled either, the default on this platform is for

This is good advice for newer machines but I've got a UBR 924 with 12.1T
code on it - 'no service password-recover' isn't an option for me. Which

do it, but I'm in no mood to experiment across twenty miles, especially
Just make sure you test the feature (for each ROMMON release you're using)
with a known enable password first. It's somewhat impossible to break into
some ROMMON versions.
