STP uplinkfast problem

At this URL:

http://www.cisco.com/en/US/products/hw/switches/ps4324/prod_release_note09186a00800aded7.html#wp26366

Cisco document said:

We do not recommend using the UplinkFast feature on switches with more than 20 active VLANs because convergence times might be unacceptably long.

Can anybody explain it ? Why convergence times might be unacceptably long ?

thanks!

Re: STP uplinkfast problem

I suspect it may be the sw/hw limitation that only Cisco internal can tell the reason.

If there is such issue, you can consider to use RSTP instead.

Hope this helps.
