We're using per-subinterface rate limiting on a 7206, talking ISL to a
2900XL switch, and it seems to be working fine. I've always just assumed
that it would work on a 26xx as well.

This works fine. About 2 years ago we were running 2621's into
Cat2924's to provide rate limited single port vlans for "smart
building" and shared tenancy projects. Worked like a charm.

You can config differents rate-limits in differents subinterface
fast/ethernet. I did it, and it works, fine... ( watch your CPU !!!)

Suppose I had a 2621 with dot1q (or isl) connection to a switch with
some customer boxes on it (customer per vlan).

Now suppose I wanted to do CAR for individual vlans.

Could I put a different "rate-limit" statement on each subinterface
and have it work? Or am I stuck with a "rate-limit" at the toplevel
and a seriously nasty policy acl?

Anyone actually having success with this? IOS version?

Thanks,

---Rob

CAR should not be used to rate-limit but instead use the MQC police command
which basically does the same thing. CAR is not going to be around much
longer and is not being developed anymore:
