Bit off topic.
I'm getting a unusual spanning-tree behaviour between a Cisco 3560 and a ALU 6850 switch.
I have rapid spanning tree set up on the ALU and Rapid-pvst on the Cisco. A few vlan's configured across a dot1q trunk.
The ALU is set with the lowest bridge priority, however both switches on all vlan's see them selves as root. With no change in the priority field.
It appears that 802.1w and Rapid-PVST are not compatible in this instance?
Any ideas? config samples if you have done this before.
Thanks in advanced
