i have a cisco 3550 with 8 gig port and 2 gig ethernet.
on 2 gig there are two vlans saperate and on the ethernet gig there is a third vlan which is connected to internal company network.both the fiber gig are connected to other 6509.
ple problem is that
from internal network which i ping to the fiber vlan network it works fine but when i ping to the ethernet port which is the third vlan it is not replying.
when i check the utilization it is 100%,
i chek the process

Hello,
you could be suffering from bug CSCdx31480:
High CPU Utilization VUR_MGR (3550)
Problem:
CPU utilization is stuck near 100% and the VUR_MGR bg process is
responsible for almost all of that CPU time. Any routing protocols
being run have converged and few if any routes are being added or
deleted.
This problem results from a relatively uncommon race condition involving
two related routes being added in close succession and the less specific
of the two routes being deleted before the add processing has completed.
Workaround:
Issue the clear ip route * command in exec mode
to clear the condition. This will not prevent the condition from
recurring, however.
A fix is planned for the next release.
Affected versions are:
12.1(12c)EA1
12.1(12c)EA1a
12.1(13)AY
12.1(13)EA1a
12.1(13)EA1b
12.1(13)EA1c
12.1(13)EA1
12.1(14)EA1
12.1(14)EA1a
12.1(14)EA1b
12.1(8)EA1
12.1(8)EA1b
12.1(8)EA1c
First fixed in version:
12.1(9)EA1
12.1(11)EA01
HTH,
Georg
