Comware

I was adding a new VLAN today when our aggregate link between our two backdone switches designed to go into standby mode.  What would cause that?  Caused a "GREAT" deal of frustration today.  I've added other VLANs in the past without incident.

Our backdone switches are A5800.  The distribution switches vary.  All are HP.

I was trying to add a Guest VLAN that should NOT be routed.  How would I do that?  There needs to be an option to specify whether each VLAN should be routed.  I think I need ACLs or something?  Is there an easy way to do it in the web interface or should I just run seperate fibers for the guest network.  Kinda defeats the purpose of VLANs.

Thanks.

On your only create the guest VLAN, but do not assign an IP addressing to it.
You'll end up with a good old layer2 VLAN without L3 routing capability

Show us the core switch log for the period when this "standby mode" happened.
