Thank you Johnny , the priority are corrected.
The problem is it happens on any vlan randomly and last time it happened was 2
weeks back.
We still have an TAC case with Cisco open for last 3 months
Cisco has asked to call them when the incident happens and to attach an
sniffer.
I was wondering if anyone faced this before.> From: johnny_d_phan@hotmail.com>
