First the troubleshooting, which might be of interest to people who use
vlans and ISL. Then my actual question. See below for commands pasted/etc.
Taking place on a Cisco 7507
So, I noticed by chance that there was ~50% packet loss from host to router
and no latency. However, the host could reach the outside world with no
packet loss and no latency. After delving into it, it looked as if the host
could ping another subnet that was bound to the same vlan ISL(6/0.1)
interface with no packet loss, but again packet loss to the actual router
was %50. Packet loss to other vlans connected via the same ISL
interface(6/0.2) was ~50% as well. So, I looked at the routers vlan/ISL
information via sh vlan. Turns out that it had a failed and removed
VIP250(0/1/0) card that was the old interface for the vlan/isl subnets. I
believe the router is trying to send half the packets to the non-existent
VIP250(0/1/0) isl interface. Now read on for the question....
I don't want to do a reload on the router, so does anyone know of a way of
"removing" this interface without reloading? It was removed successfully
upon it's failure, that is, the cbus reported it as being gone and there is
no way to 'configure int fast 0/1/0'. I made sure of this before plugging
in the 6/0 VIP250 and configuring it. Any suggestions on how to get rid of
that thing outside of reloading would be appreciated, if such a thing is
possible.
