Storm control pps is bugged on the 10g ports on the older 4900
platforms, 4948E , 4900M, sup6 platforms.
Use storm control percentage based on the 10g ports instead of PPS and
the problem won't happen.

I have a vendor trying to turn up a 10gb link from their juniper mx to
a cisco 4900M, using typical X2 LR.
The link was being upgraded from a functioning 1gb. Same traffic.
Even with switchport mode trunk and switchport allowed vlan none, with
input counters in single digits, storm control immediately takes the
port down after link up. There was negligible traffic on the link
before or after the attempt.
Vendor's best idea is to turn off storm control, which I am only going
to do with an isolated switch on site, anyone seen anything like this
or have any other ideas?
