Non-Cisco IP phones on Cisco switches

[CAWJames]

Evening all,

 

As the title suggests, I have 2 types of IP phone, a Cisco 79xx and A.N.Other, mostly Grandstreams (as they have bluetooth integrated for our jabra headsets).

 

We have 3750 Catalyst POE switches to run them all.

 

The Cisco ones do a bit of CDP magic, tell the switch it is an IP phone, it then gets put on the Voice Vlan of 5, where it gets a DHCP address from the router, and they is happy.

 

The other IP phones on the other hand just get what is programmed into the switch which is currently a standard Dynamic Auto in VLAN 1.

 

I am now trying to get the other phones into the Voice VLAN 5, but whatever setting I give the port in the switch, 802.1q/static/etc pointing to 5, I get no access.

 

I would assume static access and a setting of 5 should do it, but it doesn't! Anyone else had this b*ll ache, and have any tips?

 

Thanks

 

James

I have a Yealink T46G and it fully supports the Voice Vlan. As does a polcom phone I have.

 

Can you post a copy of the port config please?

[CAWJames]

interface FastEthernet1/0/19

switchport trunk native vlan 5

switchport trunk allowed vlan 5

switchport mode access

switchport voice vlan 5

spanning-tree portfast

 

I would have thought that would do it!

 

Weird thing is that is what is in the running-config at the moment, and in the Cisco Network Assistant it is showing Static Access:Static Access: VLAN 1 for that port. and the phones on the desks are using the VLAN 1, my head hurts! Both startup-config and running-config show the snippet above, but the switch seems to be using the config shown in the assistant, which should mirror the running-config. I need coffee, bucket of, stat

You don't setup the port as a trunk.

 

Try this config

 

switchport mode access

switchport voice vlan 5

spanning-tree portfast

 

 

if not try this, it will take the voice vlan feature out for now.

 

switchport mode access

switchport access vlan 5

spanning-tree portfast

Excellent, just did a test phone. I went straight to the CLI, defaulted the port and did the second snippet you posted, and it works, as it should. need to remember anything that gui-fy's cisco kit never works and I should stick to the CLI! They weren't meant to be trunks, they were meant to be access, but as I said, I believed the GUI! Ta muchly!

[FN-GM]

I never use the GUI as it puts stuff on you don't want!

[CAWJames]

I find, it doesn't always clear the config on a port, but adds to it, or makes it ambiguous as to what something means, as they try and put it in real world speak! Live and learn!
