we faced a problem with stp on our switch, one of our switch port is oftenly blocked on specific mst on different time intervals, bellow is our existing setup:-
we have 4 switches operates purely as layer-2 with MST configuration. we provide layer-2 vlan connectivity to customers, all switches has identical mst configuration and multiple instances configured for a range of vlans.
The problem is we have one port is oftenly blocked on mst00 at single switch due to receiving superior hellows from a customer running PVST and have been given a layer-2 vlan ID: 62 which is part of mstoo.
we have configured rootguard, bpdu guard on the port and the problem still exist occuring from time to time. I am attaching here a capture of the switch log.
could you tell me how did u figure the root of mst0 has the default priority (32768)?
have a look at the attached config for mst on the switches. also I have another question, If I use MST instances for arange of vlans , I beleive I should change the priority of specific mst rather than changing each vlan priority.
In the attached, vlan from 1-99 are not included in the mst config, but thoses vlans were considered from mst0.
