Cisco phone on Nortel data switch

[kdean9]

I am looking to install Cisco phones on a Nortel LAN (replacing cisco switches). When I manually set the admin vlan on the phone it works, but the setting disappears if I reboot the phone. I suspect the phone is TFTPing a config that overwrites my manual setting. How do I get the admin vlan to stay in the phone. I'm not a Cisco CCM admin, so details are appreciated.

The documentation states:

Admin. VLAN Id—Unique identifier of the VLAN to which the phone is attached. The value in this field is only used in non-Cisco switched networks. You can change the administrative VLAN used by the phone, however, if you have an administrative VLAN assigned on the Catalyst switch, that setting overrides any changes made on the phone.

My suspicion is you still have a Cisco switch attached somewhere on the same broadcast domain and CDP is still reaching the IP Phone overwriting the Admin VLAN setting.

Other than that you are pressing the 'Save' button aren't you?

I must ask why are you doing this though? Replace Cisco switches for Nortel ones in a Cisco CCM environment? This is just asking for trouble in my opinion.

Here is a sample of a config we inserted that seems to work okay. I'd rather use Cisco but sometimes it's all about $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$


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.

enable
config terminal

1a) ip default-gateway [default-gateway]
ip default-gateway 172.30.30.1
1b) ip address [ip address] [subnet mask]
ip address 172.30.30.2 255.255.255.0

2) vlan configcontrol [control type]
vlan configcontrol flexible

3) vlan create [vlan] name [“name”] type [type]
vlan create 100 name “Voice VLAN” type port

4) vlan members add [VLAN number] [switch ports]
vlan members add 100 1-24

5) vlan members add [VLAN number] [switch ports]
vlan members add 1 1-24

6) vlan ports [switch ports] pvid [VLAN number]
vlan ports 1-22, 24 pvid 1
vlan ports 23 pvid 100

7) vlan ports [switch ports] tagging [tagging action]
vlan ports 1-22 tagging untagpvidonly
vlan ports 23 tagging untagall
vlan ports 24 tagging tagall
