I also posted this in the switching forum, thinking maybe someone here can help too. Thanks.
I am currently trying to test using an IP phone with our new Mitel IP phone system. The phone itself is a Mitel 5220 and I am having trouble pulling a DHCP lease when plugged into a Cisco 4006 switch. When trying to pull a lease I get this error on the switch:
2005 Apr 27 18:11:58 %SYS-4-P2_WARN: 1/Tag 0 on packet from 08:00:0f:16:7e:e8 port 5/5, but port's native vlan is 98
VLAN 98 is the voice VLAN and the switch port the phone is in is on VLAN 98. But I only get that error on the switch, and on the phone it says “discovering DHCP” Now here’s the kicker, I took a Dell switch and plugged it into VLAN 98 and then plugged the phone into that Dell switch and voila, it pulls an address and works fine. The Dell switch was out of the box, with no config changes.
After seeing this, just as a test I turned trunking on, on the phone port. The above error went away, but of course I couldn’t pull an IP. The phone has a PC port on it as well so it sounds like to me that the LAN port on the phone is acting as an uplink or trunk port. ??
I am thinking there are some changes I need to make on the Cisco switch port that the phone is in, but I am unsure exactly what to do. Any guidance or help would be great.
Thanks
