Hi
Its not a vendor thing Jonathan, its a networking technique.
Lets talk about some Certain rules regaring 802.1q:
- A port can be untagged to MAX one Vlan and at least one Vlan :)
- A port can be tagged to multiple Vlans at the same time.
- A port can't be tagged and untagged to the same Vlan.
Now in ProCurve:
----------------
Untagging: SW(config)#Vlan 10 untag 1
Tagging: SW(config)#Vlan 10 tag 1
In Cisco:
---------
Untagging:
SW(config)#interface fa 0/1
SW(config-if)#Switchport mode access
SW(config-if)#switchport access vlan 1
Tagging: (Cisco recommends to shut down the interface before starting 802.1q configuration, then enable it at the end)
SW(config)#interface fa 0/1
SW(config-if)#shut
SW(config-if)#switchport trunk encapsulation dot1q
SW(config-if)#switchport trunk allowed vlan 1
Switch(config-if)#switchport mode trunk
SW(config-if)#no shut
Also:
Configure the trunking native VLAN number for 802.1Q links. This number must match at both ends of an 802.1Q uplink
So if uplink between ProCurve and Cisco, the Native Vlan on Cisco should match the Default_Vlan on ProCurve (default to one).
the command to change it is:
SW(config-if)#switchport trunk native vlan (default_Vlan ID).
Good Luck !!!
