Help a newbie with VLANS

[bodleytunes]

Hi there,

Never configured a VLAN before, and trying to work my head around a current setup that telephone engineers created when they originally setup our Mitel 3300 Phone System on the network.

All the PC's connect to the network through Mitel 5212 IP phones (they share a network port).

**Current Setup**
We have 5 x HP 2626 switches with POE.

Switch-1 = Stack Commander (This is also the default GW)
Switch-2 = Stack Member
Switch-3 = Stack Member
Switch-4 = Stack Member
Switch-5 = Stack Member
-----------------------------------------
Switch-1 Setup (Core Switch)


hostname "Switch-0"

ip default-gateway 192.168.1.251
ip routing
snmp_server community "public" Unrestricted

vlan 1
name "Data_Vlan"
untagged 2,4-10,12-26
ip address 192.168.1.251 255.255.255.0
no untagged 1,3,11

vlan 2
name "voice_vlan"
forbid 24
untagged 1,3,11
ip address 192.168.2.251 255.255.255.0
qos priority 6
tagged 2,4-10,12-23,25-26
voice
exit

ip route 0.0.0.0 0.0.0.0 192.168.1.10
ip route blar blar .... list goes on here...
stack commander "XXXXX"
stack auto-grab
stack member1 mac-address xxxxxxxxxxxxxx
stack member2 mac-address xxxxxxxxxxxxxx
stack member3 mac-address xxxxxxxxxxxxxx
stack member 4 mac-address xxxxxxxxxxxxxx
stack member 5 mac-address xxxxxxxxxxxxxx

---------------------------------------

Example Member Switch setup...

hostname "Switch-1"
ip default-gateway 192.168.1.251
snmp_server community "public" Unrestricted

vlan 1
name "Data_Vlan"
untagged 1-25
ip address 192.168.1.253 255.255.255.0
no untagged 1,3,11

vlan 2
name "voice_vlan"
ip address 192.168.2.253 255.255.255.0
qos priority 6
tagged 1-26
voice
exit

stack join 001708218500

-----------------------------------------

Now what I plan to do, is add another two switches.

However, I need to add another subnet for a new network (192.168.16.0) for a company moving into our premises.

They will be using the same phones and phonesystem as us so will need to connect to the voice Vlan via their switches and also their new VLAN subnet (192.168.16.0)

They will also need to be able to access the original data_vlan network which has a few servers on it they will need access too.

So basically the original core switch (192.168.1.251) layout will be something like

vlan 1
name "Data_Vlan"
untagged 2,4-10,12-26
ip address 192.168.1.251 255.255.255.0
no untagged 1,3,11

vlan 2
name "voice_vlan"
forbid 24
untagged 1,3,11
ip address 192.168.2.251 255.255.255.0
qos priority 6
tagged 2,4-10,12-23,25-26
voice
exit

vlan 3
name "Data2_Vlan"
untagged ???? <---- I dont know what to change this to.
ip address 192.168.16.251 255.255.255.0
tagged ??? <---- Not sure what to put here either.

--------------------

The new member switches could possibly just have voice_vlan and Data2_Vlan on it ? Or would it need the original data_vlan too?

Would I be routing via a default gateway to get back to the original VLAN?

I know it sounds a bit confusing but I've never done this before so finding my way around in the dark a bit!

Cheers!

Jonathan.
