I'm having a problem with the 7910 phones getting the correct IP information from the DHCP server. The switch (cat4006) is set up with auxiliaryvlan 3 for the phones and vlan 2 for data. I have DHCP scopes created for each vlan. When I put a phone on the network it will often get an Address from the data vlan (vlan 2) although the Operational VLAN shows correctly as 3 in the network properties. The phone will look for the call manager list for a minute and then reboot. It does this maybe 5-15 times and then eventually gets the right information. If I release the address on the phone and delete the reservation on the server enough times it will eventually come up also.
The problem seems to only be affecting 7910 phones that hang of the core 4006 switch. I have not seen the problem in remote closests.
My config for the powered port blades in the 4006 specifies auxiliary vlan 3, port channel off, trunking off and portfast on.
