Dear Sir/Madan,
We're using Polycom vvx500 phone with latest IPv6 firmware. But when we are deploying it in a pure IPv6 network it gives "DHCPv6 failed", we did the following settings on the vvx500:
1. Mode is Selected: IPv6
2. DHCPv6 is selected for bootserver.
We are using a Windwos server 2008 R2 for DHCP server, our next question is what DHCPv6 option shall i configure on the Windows 2008 R2 server to give it boot server address?
We read the uc_software_release_notes_5_5_0.pdf and as we are In IPv6 network, the following values are applicable:
• 4 - The phone uses the boot server configured
through the Server menu.
• 5 - The phone uses the boot server option provided
through DHCPv6.
We set value 5 in device.cfg,
But there is no option request in DHCPv6 Solicit packet sent by the vvx500.
Can someone give us idea what we are missing?
Please refer attached wireshark when we set value#5.
