Cisco VLAN "Trunking" & HP "tagging/untagging"?? 1

[blakey2]

Hi All,

I'm about to set up some VLANS in my environment.

I have:

F/W / Router with 1 WAN, 1 LAN, 1 DMZ interface (running pfsense)

1 X HP 2824
3 X HP 2626
4 X HP 2524

All switches support 802.1Q VLAN tagging.
The VLANS ports will be statically configured.
The 2824 will provide the inter vlan routing.

What is 'tagging' and 'untagging'? The post suggests that untagging is analogolous with ciscos 'vlan trunking':

This is confusing me!

THANKS!

Ignore that post. Trunking and VLANing are not related.
Tag a port if more than one VLAN will be using it. Otherwise leave it untagged.

From the 53xx manual VLAN chapter:

Any port that has two or more VLANs assigned to it can have one VLAN assignment for that port as "untagged". All other VLANs assigned to the same port must be configured as "tagged" (there can be no more than one untagged VLAN on a port).

If all end nodes on a port comply with the 802.1Q standard and are configured to use the correct VLAN ID, then you can configure all VLAN assignments on a port as "tagged" if doing so makes it easier to manage your VLAN assignments, or for security reasons.
