ProCurve 2810 Voice Vlan and Trunk Help

[paddy27]

Hi,

I have a scenario that I need to create a voice vlan and create trunk port for uplink which connects to cisco router.

We have two switches 2810-48 and 24. They are connected via Trunk (45-48 to 21-24)

Here is the current switch configuration:

Switch1
hostname "ProCurve 2810-48G"
trunk 45-48 Trk1 Trunk
ip default-gateway 192.168.0.254
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-44,Trk1
ip address 192.168.0.102 255.255.255.0
exit
spanning-tree Trk1 priority 4

Switch2
hostname "ProCurve Switch 2810-24G"
trunk 21-24 Trk1 Trunk
ip default-gateway 192.168.0.254
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-20,Trk1
ip address 192.168.0.101 255.255.255.0
exit
spanning-tree Trk1 priority 4

First of all, I need to create a trunking with vlan 100 (Voice) on uplink which connects to cisco router. Port 12 will be used to connect to uplink.

My configuration would be like this:

ProCurve 2810-48G#(Config)#vlan 1
ProCurve 2810-48G#(Vlan-1)#untagged 1-11,14-44
ProCurve 2810-48G#(Vlan-1)#tagged 12 //Enable Trunk on port 12 connecting to Router
ProCurve 2810-48G#(Config)#Vlan 100
ProCurve 2810-48G#(Config)#name "VOICE"
ProCurve 2810-48G#(vlan-100)#tagged 12 //Enable Trunk on  port 12 connecting to Router
ProCurve 2810-48G#(vlan-100)#untagged 13 //Connect to IAD (VINE2000) and IAD will connect to IP-PBX which all non-ip phones are connected.

Is this correct? or am I missing something here?

You would have to provide the router config so we can be sure.

The implication fropm what you have provided is that the router has two subinterfaces configured, one for each VLAN, both of which are dot1q tagged (neither is native).

The subinterface for VLAN1 has the ip address 192.168.0.254 on it.

I think you might want to configure 

vlan100 tagged trk1 on each switch, as well. Maybe.

Please have a look at the attached network diagram.

Could you please check the configuration with the diagram if they are okay?

Here is my fianl configuration

hostname "ProCurve 2810-48G"
trunk 45-48 Trk1 Trunk
ip default-gateway 192.168.0.254
snmp-server community "public" Unrestricted

vlan 1
   name "DEFAULT_VLAN"
   untagged 1-10,13-44,Trk1          //untagged port - internal PCs and servers are connected
   ip address 192.168.0.102 255.255.255.0
   tagged 11                                        //tagged port for cisco router 1941 series (inter-vlan has been configured)
   no untagged 12
   exit

vlan 100
   name "Voice"
   untagged 12                            //untagged port (access port in cisco term) for phone system -PBX
   tagged 11                              //tagged port(trunk port in cisco term) for cisco router 1941 series (inter-vlan has been configured)*
   voice
   exit
spanning-tree Trk1 priority 4

Could someone please confirm the configuration is correct for me?

I guess it should work.

A couple of things I would usually try to avoid:

 - using VLAN1

 - having hosts on the same broadcast segment as both the switch layer3 and a router.

But really, if you want to use VLAN1, why not, and if the switch IP address is only used for switch management, and you don't feel like creating a seperate VLAN for the hosts, again, why not.

Some people said that I should make port 11 to be untagged port as it sohuld be native vlan.

What would you think?

[Vince-Whirlwind · Accepted solution]

It depends on how the Router is configured. If the router has one of the VLANs configured as "native" on the link then you will need to make that VLAN untagged on the link.
