Per VLAN Spanning Tree in HP A5820X Switchs

Hello,

 

As peer I know "Per Vlan Spanning Tree Plus PVST+" is not supported by many HP Switchs. Is it supported by HP A5820X  products?

 

I Could not find this information in the product specifications.

 

Thanks & Regards

Hi Lhaj

 

PVST+ isn't supported on the A5800 family. But on the switch A3600v2.

I've no such switch, but we like to buy it because we need also this feature

 

Regards

Isn't PVST+ Cisco proprietary? I don't think any A-Series switch support the feature.

PVST+ runs on 802.1q links. 802.1q is a networkingstandard promulgated by the IEEE.

PVST is the implementation of STP on ISL links (Cisco proprietary multi-VLAN encapsulation).

PVST+ is Cisco proprietary. Some vendors use it, under licence from Cisco, one assumes.

A-Series switches support IEEE 802.1s MSTP, which is much faster than PVST+, I don't see any reason to run PVST+ on an A-Series switch.

the Customer IP Backbone switchs are running PVST+. Therefore we are forced to adapt to the existing.
