Spanning-Tree MST

[jay_7301]

Hi,

we have the following configuration on our switches

spanning-tree mode mst

spanning-tree extend system-id

!

spanning-tree mst configuration

 name test

!

spanning-tree mst forward-time 4

when we have a failover convergence time was about 8-10 seconds outage is there anything on the above config that suggest's this could be causing the delay? i thought MST was fast convergence times?

Thanks

Hello.

could you please provide "show span-tree summ" and your network diagram with description of failover event?

PS: what is the reason to run MST and not RSTP?

i will try and you this later on. Not sure it was already in place what are the difference's between them both i thought MST can have multiple vlans per region so better design. Is RSTP not the same as PVST? not done much spanning tree as of yet. so not had chance to look at the differences?

Thanks
