Someone here must have an answer for this one. Cisco TAC has been
absolutely NO HELP. I am sure that 600+ heads in this group, together,
can help me with this problem. I have to implement this thing tomorrow
evening. I am sure that I will get lot of calls from unhappy customers
about the latency issue.
PLEASE HELP.
