A5500 and Cisco Config ??

[ccavanna]

Hi -

I have to interconnect my new A5500 switches for our san network to our current Cisco Catalyst 3020 blade switches. I have read through the HP ASE manual and would like to double check things since this is the san network. The cisco's vlan is setup using vtp but its already using 802.1q tagging and not cisco's isl's. Any help would be great!

Thanks

A5500 Config

#

vlan 2

interface Bridge-Aggregation13

 description Trunk to Blade 
 port link-type trunk
 undo port trunk permit vlan 1

I think you are missing the PVID (5500) and the Native VLAN (Cisco).

In the 5500:

interface Bridge-Aggregation13

port trunk pvid vlan <vlan_id>

In the Cisco:

int po1

switchport trunk native vlan <vlan_id>

encapsulation dot1q

Since you denied the VLAN 1 (default native VLAN and PVID) passing through the trunk, you have to tell the switch what is the PVID of the trunk - which means that in the Cisco switch you have to setup the native vlan (PVID).

@Fred: no native vlan is needed. It works without on A-Series and cisco

@ ccavanna:

In my opinion the link-aggregation on A-Series is misconfigured. Konfigure the vlan on the bridge aggregation AFTER you have added the ports to the Aggregation group. Then the BR will add the VLAN-config the the physical ports. => see "display log" and "display link-aggregation v".

I am not sure, but i think it's the same on cisco.
