Help configuring VLAN's GbE2c to 5412zl

Hi there,

I have an c7000 blade system with and GbE2c ethernet switch.
This GbE2c is connected via 4 trunked uplinks to my 5412zl switch.
So far so good. Everything is working fine with the default VLAN1.
We have a DMZ VLAN 5 on the 5412zl switch.
On the blade system there are virtual machines via XenServer who need to be connected to the DMZ. In XenServer i can make a tagged network connecting to VLAN5.
How do i configure the GbE2c switch?
Just enable tagged to all ports (also trunked ones) and put them in the VLAN5 ?
I've done that :) and there was no traffic possible anymore.

No experience with HP switches, but in Cisco side for 802.1q, you have to configure port or portchannel mode trunk. So you can add allowed vlan for it.

find here an example in cisco.

interface GigabitEthernet1/0/1
switchport trunk native vlan 111
switchport trunk allowed vlan 111,222,333
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
