HP ProCurve VLAN trunking to Cisco

[gbljoba]

Hi,

Im missing something obvious here......

I have a HP Procurve 5406 connected to a Cisco 3560 on a temporary cat5e connection and I have Mitel IP phones needing to go on the Cisco switch.

Ive configured the HP Procurve port to TAGGING both VLAN 10 (data) and VLAN 20 (Voice). NO is selected for default VLAN 1.

The Cisco is configured on the port with switchport encap dot1q and switchport mode trunk.

Ive configured an IP for interface VLAN 10 and i cannot ping it from across the network. The interfaces are up and happy. I have tried changing the VTP status from transparent to server (VTP pruning is off) ive tried setting allowed vlans 10,20. Still not a think.

Have i missed something?

The worse thing is that i have a working Cisco switch with the HP procurve that i checked the config on and its the same! The only difference is that the media type is SX over SFP in that case.

p.s not that im at this stage yet but i initially configure the FastE ports as trunks with native vlans because i was using non-cisco phones. On a spare port i convigured the voice vlan 20 and i say on the mitel phone that it was looking on vlan20! I didnt expect that, i thought the Voice VLAN ID was carried on CDP enabled devices only.

Jon,

The CAT5e cable, is it a crossover between the switches?  Does it show the link up on both sides.

Hi,

Yes the link is UP on both sides. Both sides are supporting MDIX.

I guess you are trying to ping the SVI of Vlan 10?

I know im stating the obvious but have you assigned a port to vlan 10?

[Giuseppe Larosa]

Hello Jon,

as suggested by Solpandor you should verify

if you like use and post:

sh vlan id 10

sh vlan id 20

sh spanning-tree vlan 10

sh spanning-tree vlan 20

sh int vlan 10

there is a feature that on C6500 is called autostate that links the state of SVI vlan10 (L3 object) to the existence of a L2 port (access or trunk) in STP forwarding for vlan10. The feature is present in all multilayer switch.

Hope to help

Giuseppe

All ports are in FWDing stats on both sides, to be safe, i changed the priority.

I really appreciate this

Hello Jon,

Can you please also post the configuration of the Gi0/1 interface on your 3560 and the configuration of VLANs 10 and 20 from your HP ProCurve switch? Also, I would be interested in seeing the show interfaces trunk plus show mac address-table int gi0/1 on the 3560 and show mac-address N on the HP (where N is the port going towards the 3560) to see if the  the ports are actually learning MAC addresses at all.

Best regards,

Peter

I beleive it is explained well on the following blog

I know this is an old question, but I've been struggling with this this week, for anyone else following up this might help,

Try using the switchport trunk non negotiate on the Cisco switch.
