Cisco 7941G Administration Guide

Network Settings Configuration MethodAuto IP ConfigurationDHCPv6
When the M-bit is set on the router, the O-bit is
ignored. The phone can set its IPv6 address based on
an IPv6 address received from a DHCPv6 server or
the phone can acquire its IPv6 address through
stateless address autoconfiguration.
When the M-bit is not set, you should set the O-bit on
the router. The phone will then acquire its IPv6 address
through stateless address autoconfiguration. The phone
will not request an IPv6 address from the DHCPv6
server, but it will request other network configuration
information.

Device Configuration Menu
The Device Configuration menu provides access to eight submenus from which you can view a variety of
settings that are specified in the configuration file for a phone. The phone downloads the configuration file
from the TFTP server.
For instructions about how to access the Device Configuration menu and its sub-menus, see Display Settings
Menu, on page 60.
Unified CM Configuration Menu
The Unified CM Configuration menu contains the options Unified CM1, Unified CM2, Unified CM3, Unified
CM4, and Unified CM5. These options show the Cisco Unified Communications Manager servers that are
available to process from the phone, in prioritized order. To change these options, use Cisco Unified
Communications Manager Administration, Cisco Unified CM Group Configuration.
For an available Cisco Unified Communications Manager server, an option on the Unified CM Configuration
menu will show the Cisco Unified Communications Manager server IP address or name and one of the states
shown in the following table.
