The Cisco 7600/sup720 12.2SR releases only supports the original 50K/10K
limit in 12.2SXF.
I have 6500/sup720 and 7600/sup720 running much higher virtual-port
loads under 12.2SXF using MST. I tried to get the BUs to re-test the
STP capacity limits via our account team, but there wasn't a lot of
interest. The 7600 BU may decide to add the 12.2SXI STP scalability
enhancements to a 12.2SR release at a later date.

Hi Matt,
The 6500/sup720 on 33SXI supports 100K logical ports in MST, and 12K
in RPVST. That's up from 50K/10K in every prior release.
N7K supports 75K in MST & 16K in RPVST today. There are no per-module
limitations on N7K.
Those numbers are based on the requirements we expressed to QA/system
test prior to FCS. The original numbers were confirmed prior to 33SXI
was released. Since then, we have not had a customer
requirement/request to support more, so frankly we have not felt
compelled to go and requalifify for anything greater. Would be curious
to know how many logical ports you are running today & in what protocol?
Thanks,
Tim
