VLAN taggings always throws me for a loop. I have a HP Procurve 5412zl and a Dell Powerconnect 6248. Currently the Procurve has multiple VLANs on it and 1 of those VLANs extends to the Dell switch, but the Dell switch (as far as I'm aware) is not aware of the VLAN. To clarify the Dell is pretty much out of the box but the port it plugs into on the Procurve is untagged on VLAN 2. Now I need another VLAN to be able to be used on the Dell Switch.
So my question is how do I tag the ports that connect to the Dell switch so I can use both VLANs.
My assumption is when this is done the default VLAN of the switch will be VLAN2 and if I want something to work on the new VLAN I'll need to untag that port accordingly on the Dell switch.
