Comware

Hi!


I will install 2 5406 in core, and have about 3 2810 on each floor (edge switches). I will have 30 vlans in core, and about 4 on each floor.
I will use MSTP with two instance, have odd vlan tag on one instance, and even on the other one for loadbalance.

But is it ok to have only a couple of these vlans assigned to same spanning tree instance on edge switches?

Best Regards, Magnus

You really should match each switch in the MSTP region to have the exact same spanning-tree configuration so that the digests match:

ProCurve Switch 5406zl# show span mst-config

MST Configuration Identifier Information

MST Configuration Name : 001b3f4eaf00
MST Configuration Revision : 0
MST Configuration Digest : 0xAC36177F50283CD4B83821D8AB26DE62

The 5400's allow you to specify VID's in your MSTP configuration that don't yet exist. The 2810's I don't think have this feature quite yet.

Thx. Is it possible to have edge-switches "automatic" get MSTP config from core-switches? Or is it possible to have "odd/even" as vlan id ?

Or should I build different MSTP region ? One for all floor (6 floor), and one for datacenter? Best practice ?
