Chapter 2 Server Configuration
Server Configuration Settings
IPv6 Name This field supports IPv6. If your network uses DNS that can map to IPv6
addresses, you can enter the host name of the Cisco Unified
Communications Manager server. Otherwise, enter the non-link-local IP
address of the Cisco Unified Communications Manager server; for
information on how to obtain the non-link local IP address, refer to
“Running IPv6 CLI Commands or Configuring IPv6 in the Ethernet
IPv6 Window” in the Cisco Unified Communications Manager Features
and Services Guide.
This field, which gets included in the TFTP configuration file, gets used
by phones that run SCCP to retrieve the IPv6 address of the Cisco
Unified Communications Manager server, so phone registration occurs.
Tip Remember to update the DNS server with the appropriate Cisco
Unified Communications Manager name and address
information.
Caution If your network supports IPv6 or IPv4 and IPv6 in dual-stack
mode, you can provision your DNS server for IPv6 prior to
upgrading from Cisco Unified Communications Manager
Release 7.0(1) to Release 7.1(2). However, do not configure
the DNS records for Cisco Unified Communications Manager
for IPv6 until after you upgrade to Release 7.1(2).
Configuring the DNS records for Cisco Unified
Communications Manager for IPv6 prior to upgrading to
Release 7.1(2) causes the upgrade to fail and causes your
system to become nonfunctional after you reboot.
Tip In addition to configuring the IPv6 Name field, you must
configure the IP Address/Hostname field, so Cisco Unified
Communications Manager can support features/devices that use
IPv4 (or IPv4 and IPv6).
MAC Address Consider this entry as optional.
Enter the media access control (MAC) address of the network interface
card (NIC) in the Cisco Unified Communications Manager server. The
MAC address specifies the permanent hardware address of the NIC.
Tip If you plan to move the server periodically to different locations
on the network, you must enter the MAC address, so other
devices on the network can always identify the server. If you do
not plan to relocate the server, consider entry of the MAC
address as optional.
Description Consider this entry as optional.
Enter a description of the server.
