Nortel Router & Switches for VoIP

Programming Nortel Ethernet Routing Switches
for VoIP, and PC connectivity to Phone

1) Provision switch with IP information

2) Set VLAN configuration control to Flexible

3) Build voice VLAN

4) Add ports to voice VLAN (all ports with a phone and/or data connection must be members of voice and data VLANs.)

5) Add ports to native VLAN (all ports with a phone and/or data connection must be members of voice and data VLANs.)

6) Set default VLAN on ports (all ports with a phone and/or data connection and uplink ports should have a default VLAN of the native VLAN 1, ports connected directly connected to the phone system should have a default VLAN of the Voice VLAN)

7) Set VLAN tagging on ports (all ports with a phone and/or data connection should be set to untag the default VLAN, all uplink ports should be set to tag all VLANs and ports directly connected to the phone system should be set to untag the Voice VLAN)

Sample configuration steps

Assume that the router is already programmed for dot1q encapsulation; with vlan 1 as the data vlan and an ip address of 172.30.30.1/24, as well as vlan 100 as the voice vlan and an ip address of 10.30.30.1/24. Also assume that ports 1-22 on a 24 port switch will be used for voice and data connectivity, while port 23 will be used for connectivity to the phone system and port 24 will be the trunk/uplink port to the router.
