ERS4550T using LLDP to modify VLAN on 9608 taking forever

[bluebells11]

I have a customer that does not have a DHCP server, so I am using LLDP in the ERS4550T to modify the VLAN-ID on their 9608s. Once the VLAN has been modified I am using the IPO V2 as a DHCP server for the phones only. Everything is working as expected, with one exception. When the 9608 boots it takes 26sec to switch to the Voice VLAN. Once it does it gets an IP from the V2, downloads, and waits to be logged in. I was hacking my way through this on a switch that I had laying around the office a few days ago and I remember it only taking 3-4sec. Unfortunately I restored that switch and put it away, AND didn't save a config (I thought I did). Any ideas as to what is causing a 26sec delay. I do realize that 26sec is not quite forever, but it sure seems that way when you are watching it.

Thanks,
E

On your interface:
spanning-tree rstp edge-port true

OK. Here's my config. I added the two spanning tree rstp statements to an existing config. When I plug a phone in I am still waiting 30sec for the VLAN to switch. Can you see anything I am missing?

Set the logging to informational or debug and try again, then view the log and look at the timing of the log events relating to the port you are testing.
If the port isn't coming up in about 2 seconds, then reboot the switch.

What IP address exactly is the phone getting, eventually?
How do the phones get their Voice VLAN?
Why do they have a routed interface in VLAN3 but none in VLAN2?
I'm guessing there is a router p[atched to this switch, on VLAN2?
