Avaya IP Office Network Port Usage

[Jim Mc]

Hi,

We have an engineer putting in an Avaya IP Office 500 system next week. It will have IP phones and use SIP. We're setting up the network to accommodate it. What we would like to do is the have the IP phones on their own VLAN, to be able to manage the IP Office from a PC on our LAN, and use SIP. This would appear to require three networking ports, but the IP Office only has two. Can someone advise on the best way to accomplish this?

Thanks,

Jimmy.

You wouldn't connect the IPO to all networks the same way you don't have 3 interfaces on all your servers.
You put the IPO on one network and then you allow the VoIP VLAN, Management VLAN etc access it on the ports needed.

Connecting IPO on several networks makes it possible to use the IPO as a router between you networks and bypassing security.

That sounds perfectly fine, so perhaps the question should be "how do I use VLANs on the Avaya?" - I cannot see where to enable VLANs on the IP Office anywhere in their documentation?

Our data network is on 10.0.11.0/24 and we would like to give the IP Office an address of 10.0.11.251 on VLAN 1 to manage it.
The SIP trunk endpoint is on 172.16.0.0/30 and we would give the Avaya an IP address of 172.16.0.2 on VLAN 30
The IP telephones would use the Avaya IP Office as a DHCP server on 192.168.20.0/24 on VLAN 5

Thanks.

If you have an engineer coming over I don't understand why he hasn't already discussed this with you, I would see it as a part of the implementation process.

Personally I would have the IPO on a fourth network with routing and ACLs to the other 3.
I also never use the IPO for DHCP except in the rare cases where it's isolated from everything else.
