We have recently purchased a Mitel solution from our local phone provider. The controller (3300 MXE III I believe) and several phones have been installed in a new building and appear to be working fine. However, when we plugged a phone into the network here in our IT building, the phone will not get pass "DHCP Discover Using Option 128+". The only difference between the two is that the IT building is on a different subnet and thus has a different VLAN.
I have the following options configured on our DHCP server:
I plugged a computer into the very same port that the affected phone is plugged into. It pulled an IP address from the DHCP server for the appropriate subnet and I was able to not only PING the controller, but also establish a session with it on more than 50 different ports. So I'm not inclined to think it is a network issue.
Here is the boot process that the phone (5320e) goes through:
- Waiting for 802.1x authentication
- Waiting for LLDP
- Main Ver 05.01.00.09 / Boot Ver 05.01.00.03
- Waiting for DHCP / Main Ver 05.01.00.09
- VLan None Pri None / Main Ver 05.01.00.09
- DHCP: Discovery / Main Ver 05.01.00.09
- DHCP: Discovery / Using Option 128+
- DHCP: Releasing / Using Option 128+
- VLan 201 Pri 6 _ / Using Option 128+
- DHCP: Discovery / Using Option 128+
It stays at the last option until it times out and then it recycles.
Any help would be greatly appreciated.
