Re: Multivlan on ports 5412 zl
all traffic including broadcast stay within a vlan and won't be forwarded to the other vlan.
you don't want the same broadcast address?
then use different subnets, each has it own broadcast address
like 192.168.1.0/24 -> range 192.168.1.1 to 192.168.1.254; broadcast 192.168.1.255
and 192.168.2.0/24 -> range 192.168.2.1 to 192.168.2.254; broadcast 192.168.2.255
or 192.168.1.0/25 -> range 192.168.1.1 to 192.168.1.126; broadcast 192.168.1.127
and 192.168.1.128/25 -> range 192.168.1.129 to 192.168.1.254; broadcast 192.168.1.255
if you want the networks to communicate with eachother you need to configure one of the switches as a router (or a dedicated router).
routers don't forward broadcasts, so the broadcasts stay isolated in their own vlan.
on a switch
- for each vlan configure an vlan interface and assign it a ip-address
- enable ip routing
in each vlan configure the clients to use the switch as the default-gateway.

Re: Multivlan on ports 5412 zl
I think the divice top-centre is your core?
Why use both vlan3 and vlan215 for voice?
on the core switch do :
vlan 2
tagged H1-H4
exit
vlan 3
tagged H1-H4
exit
on the edge switches do :
vlan 2
tagged H1
exit
vlan 3
tagged H1
exit
connect H1 on all these switches with H1-H4 on the coreswitch.
and :
vlan 2
untagged H2-H24
exit
vlan 3
tagged H2-H24
exit
for the edgeports
configure routing on the core
ip routing
vlan 2
ip address 10.0.0.1 255.255.255.0
exit
vlan 3
ip address 10.29.0.1 255.255.255.0
exit
Does this cover the question?

Re: Multivlan on ports 5412 zl
basically you can.
but on a single port:
- only one vlan can be untagged
- other vlans must be tagged
- the device connected must be able to handle tagged packets.
digging deeper into the last line :
- switches and routers can handle tagged packets and so transport multiple vlans on the same port .
- most Pc's normally only handle untagged packets.
- to handle multiple vlan's on a single NIC on a PC or Server you may need to install a vlan-aware NIC driver. (HP proliants with teaming software can).
