3750 stack spanning tree

Hi All,

We have couple 3750 all stackup and connecting to pair of 6509 switches running hsrp.

I'm not sure if this is normal or not, but problem we seeing is that if do ping from stack switch to the hsrp address

and then remove a link to master hsrp there is no lose, now if we then connect link back and disconnect the second

link we have about 30 second where we lose ping.

we have configured the uplink-fast/backbone-fast etc on the STACK switch. But we still have this problem.

Regards
