trunk multiple vlan on 4204vl

Hi

I have a 4204vl that can't do ACL so i want to trunk all my vlans on the switch on one port and connect to a linux that i will be using for routing and acl. This image below is pretty much what i want to do. instead of a cisco its a hp procurve 4204vl.

Thank you and sorry for my bad english :)

Hi,
in the HP world to have more than one vlan at one port you need to tagg the port into the vlan.
conf
vlan 100
tagged a1
wr mem
exit
exit

Re: trunk multiple vlan on 4204vl

in all networking but cisco, trunk generally means multiple ports "bonded, trunk, LACP" together to make a bigger 'pipe'...

tagged means multiple vlans traveling on the same link (individual port or trunk group)...the packet is modified (802.1Q) with an additional 4 bytes that carries the vlan-id and priority (QoS)...

untagged means single vlan only on port...

LACP = link aggregation control protocol
802.1Q = standards definition of tagged/untagged

cisco - procuvre (and most everyone else)
trunk - tagged
access port - untagged
etherchannel - trunk/LACP

Re: trunk multiple vlan on 4204vl

Hi,
with LACP you can channel multiple ports to act like one port. you have more bandwith. this has nothing to do with your two vlans over one port. the cisco trunked port is the same as the hp tagged port.

Re: trunk multiple vlan on 4204vl

All rigth, so is it possible or not to concentrate all vlan to one port so i can route and contrôle trafic with a linux router with only one interface with virtual vlan instead of having multiple interface by vlan ?

Re: trunk multiple vlan on 4204vl

Hi,
that is what everybody is trying to explane you.
You can do this, you just need to tag the port to all those vlans you want on that port.
for example:
conf t
vlan 100
tagged a1
exit
exit
wr mem
you do this with every vlan you want on the port and there you go.
