Network [1..1] IPv6 Assignment
Define how the system will obtain its IPv6 address and the default gateway address. This
setting only applies to systems on IPv6 networks.
Requires user role: ADMIN
Value space: <Static/DHCPv6/Autoconf>
Static: The codec and gateway IP addresses must be configured manually using the Network
IPv6 Address and Network IPv6 Gateway settings. The options, for example NTP and DNS
server addresses, must either be set manually or obtained from a DHCPv6 server. The
Network IPv6 DHCPOptions setting determines which method to use.
DHCPv6: All IPv6 addresses, including options, will be obtained from a DHCPv6 server. See
RFC 3315 for a detailed description. The Network IPv6 DHCPOptions setting will be ignored.
Autoconf: Enable IPv6 stateless autoconfiguration of the IPv6 network interface. See RFC
4862 for a detailed description. The options, for example NTP and DNS server addresses,
must either be set manually or obtained from a DHCPv6 server. The Network IPv6
DHCPOptions setting determines which method to use.
Network 1 IPv6 Assignment: Autoconf
Example:
Network [1..1] IPv6 Address
Enter the static IPv6 network address for the system. This setting is only applicable when the
Network IPv6 Assignment is set to Static.
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: A valid IPv6 address.
Network 1 IPv6 Address: "ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff"
Example:
Network [1..1] IPv6 Gateway
Define the IPv6 network gateway address. This setting is only applicable when the Network
IPv6 Assignment is set to Static.
Requires user role: ADMIN
Value space: <S: 0, 64>
Format: A valid IPv6 address.
Network 1 IPv6 Gateway: "ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff"

Network [1..1] IPv6 DHCPOptions
Retrieve a set of DHCP options, for example NTP and DNS server addresses, from a DHCPv6
server.
Requires user role: ADMIN
Value space: <Off/On>
Off: Disable the retrieval of DHCP options from a DHCPv6 server.
On: Enable the retrieval of a selected set of DHCP options from a DHCPv6 server.
Network 1 IPv6 DHCPOptions: On
Example:
Network [1..1] DHCP RequestTFTPServerAddress
This setting is used only for video systems that are registered to a Cisco Unified
Communications Manager (CUCM).
The setting determines whether the endpoint should ask the DHCP server for DHCP option 150,
so that it can discover the address of the TFTP server (provisioning server) automatically.
If this setting is Off or the DHCP server does not support option 150, the TFTP server address
must be set manually using the Provisioning ExternalManager Address setting.
Note: If the Network VLAN Voice Mode setting is Auto and the Cisco Discovery Protocol (CDP)
assigns an ID to the voice VLAN, then a request for option 150 will always be sent. That is, the
Network DHCP RequestTFTFServerAddress setting will be ignored.
Requires user role: ADMIN
Value space: <Off/On>
Off: The video system will not send a request for DHCP option 150 and the address of the
TFTP server must be set manually. See the note above for any exception to this rule.
On: The video system will send a request for option 150 to the DHCP server so that it can
automatically discover the address of the TFTP server.
Network 1 DHCP RequestTFTPServerAddress: Off
