HP layer 3 with voice vlan

[RWitte]

I am working on a 10 ipo scn that is linked with fiber to 10 HP layer 3 switches that the data vendor built separate voice vlans for each. I bult ip routes with the hp ip address as the gateway and have the scn in a star all going to 1 ipo. The data vendor cant get the broadcast from ipo to see the other switches, manager only sees the ipo on the vlan it is on. Is there any info i can pass on to them to get this project into high gear thanks

You need to search for the other IPO's by there respective IP's you cannot broadcast across VLANs. You do this by changing the Broadcast IP from 255.255.255.0 to the IP of the IPO you want to work on.

I was under the assumption that if the broadcast didnt work the ip office didnt communicate, The scn right now doesnt work, I believe that i have everything programmed correctly, is there anything differnt i need to look at because its a vlan and not routers.

check if the ports are open for the SCN
Port 50795 IPO Voice Networking (UDP) Small Community Network signalling (AVRIP) and BLF updates. Each system does a broadcast every 30 seconds. BLF updates are sent required up a maximum of every 5 seconds.

If you can't be good, be good at it!

Did you make an iproute to the gateway (every ipo needs it)
The gateway knows what to do
The iplines should point to the ipo it needs

You can also put a second networkcard in the PC witch is conneted to the voice VLAN untagged.

Every IPO points to the ip of the IPO in site 3 and site 3 has 9 ip routes pointin to the ip in each remote site. They all have a ip route with 0.0.0.0, in the first 2 fields and the ip of the voice vlan gateway from the switch they are in ie ipo is 10.10.12.10 and has a gateway of 10.10.12.1 all have a subnet mask of 255.255.255.0

Can you ping the other ipo's ?
Can you pull the config of the other ipo's ?

It sounds like the programming on the IPO's is correct, is the gateway in each of your IP lines set to the IP of the IPO it is programmed to connect to? If so your switch/router configs are going to be your issue here, what model HP switch are you using 2600 series?

If i enter in the ip instead of the 255.255.255.255 in manager i can connect to the other ip offices

 

[RWitte]

the ip line gateway is set to the the gateway address of the switch it is connected to,
IPO site 1
10.10.12.10 lan 1
ip line 10.10.32.10 site 3 ip address
ip route
0.0.0.0
0.0.0.0
10.10.12.1 gateway of switch

IPO site 2
10.10.22.10 lan1
ip line 10.10.32.10 site 3 ip address
ip route
0.0.0.0
0.0.0.0
10.10.22.1 gateway of switch


IPO 3
10.10.32.10 lan 1
ip lines
10.10.12,22,42,52,62,72,82,92,102,.10
ip route
0.0.0.0
0.0.0.0
10.10.32.1

and so on all have a start lic

your gateway adress is a VLAN router adress, as far as i know a broadcast will nog go over a router.

Have you filled in the IP helper adress on the switch?

Instead of doing a broadcast in the IPO IP route i should put in the address of the ip office ?
ipo site 1
10.10.12.10 lan 1
ip line 10.10.32.10 site 3
ip route
10.10.32.10
255.255.255.0
10.10.12.1
is this what you mean
thanks for all the help

 

[Bas1234]

Is the switches can handle it programm a IP or UDP helper adress, this will route the broadcast over the VLAN.

Are the SCNs active can the switches see each other?

the switches do not see each other i believe its a routing issue with the hp switches and the data vendor doesnt seem to know much about voip just want to see if i can give him some insite and myself also, udp and broacast ports that need to be opened etc

 

[djuplift]

You cannot broadcast across subnets this will not work each subnet is its own broadcast domain, so seeing the remote IPO's with Manager will require changing the broadcast address to the address of the IPO you want to work with.

If the SCN's are not active and you cant ping them you definitely have a routing issue.

Are you able to post a running comfig from one of the HPO switches?

Here is a proper HP switch config:

Also the IPO's and Voicemail servers must be on Untagged ports if you are using Overlapping VLANS.
