Hi guys,
We have recently upgraded parts of our network, as well as upgrading from PVST to RPVST.
Problems have come along where the wireless links between the switches do not cope with topology changes, but this is a whole other problem.
The actual problem comes from linking between two switches with two wireless links.
Logging on the remote switch shows RSTP moving to the second link due to lack of root BPDUs on the primary radio circuit. Yet 2-3 seconds later it shifts back to the primary link. In doing this it is causing problems further on down the network.
During some of my reading of STP I found a page explaining all the timer details as well as an option to do debugging on BPDU packet timings. All I remember was that it was an option which would log timing faults on BPDU packets.
Other than finding this command, are there any other options for BPDU debugging/logging to find out why its selecting the secondary.
056650: Mar 23 22:22:39: RSTP(10): updt roles, root port Fa0/16 is going down
056651: Mar 23 22:22:39: RSTP(10): Fa0/17 is now root port
Now using pings to the remote switch shows no problems the entire time, we are using default timers, which should mean that traffic should stop to the remote site for at least 6 seconds.
Any & all help is appreciated, and pre thanks to Francois
Regards Richard
