Cisco Unified IP Phone 7931G Administration Guide for Cisco Unified Communications Manager 8.0 (SCCP and SIP)

OL-20798-01

Chapter 4 Configuring Settings on the Cisco Unified IP Phone

Network Configuration Menu

IPv6 TFTP Server 1

(SCCP phones

only)

Primary IPv6 (TFTP server used by the phone. If

you are not using DHCPv6 in your network and

you want to change this server, you must use the

IPv6 TFTP Server 1 option.

If you set the IPv6 Alternate TFTP option to yes or

you disable DHCPv6, you must enter a non-zero

value for the IPv6 TFTP Server 1 option.

If you make changes to the Alternate TFTP or

IPv6 TFTP servers, you must first unlock the CTL

or ITL file on the phone.

When the phone looks for its TFTP server, it gives

precedence to manually assigned TFTP servers,

regardless of the protocol. If your configuration

includes both IPv6 and IPv4 TFTP servers, the

phone prioritizes the order that it looks for its

TFTP server by giving priority to manually

assigned IPv6 TFTP servers and IPv4 TFTP

servers. The phone looks for its TFTP server in the

following order:

1. Manually assigned IPv6 TFTP Servers

2. Manually assigned IPv4 TFTP Servers

3. DHCPv6 assigned TFTP Servers

4. DHCP assigned TFTP Servers

Note For information about CTL and ITL files,

see the Cisco Unified Communications

Manager Security Guide. For information

about unlocking CTL and ITL files, see

Security Configuration Menu, page 4-35.

1. Unlock the CTL or ITL file, if necessary. If the

CTL and ITL files both exist, unlock

either file.

2. If DHCPv6 is enabled, set the IPv6 Alternate

TFTP option to Yes .

3. Scroll to the IPv6 TFTP Server 1 option, press

the Edit softkey, and then enter a new TFTP

server IP address.

4. Press the Validate softkey, and then press the

Save softkey.
