Hello,
We we have an office which is using a hosted IP provider but they just have 15 x non Cisco desk VOIP phones and have their PC's plugged into them all on VLAN 1.
I've created 2 VLANs there, 1 for Data and the other for Voice, would I just need to make the switch ports a trunk and set the phones to the voice vlan?
Any example port configs woud lbe great. They don't have QoS either which I may add.
Thanks

Thanks,
That is how I did it, the only thing I have missing is "lldp run" what is that?

Hi Andy,
I am very glad that you got the configuration right.
LLDP is a replacement for CDP.
CDP is to detect the neighbor device(Cisco) and LLDP can be used for Avaya.
Thanks

Just one thing I noticed I didn't use the "switchport trunk native vlan x" would this be for anything untagged?

"switchport trunk native lan x" is the replacement for "switchport access vlan x" in both the cases the VLAN will not be tagged.
Thanks
