Description
Releases the IPv6 address that the phone has
acquired from the DHCPv6 server or by
stateless address auto configuration.
This field is only editable when the
Note
DHCPv6 option is enabled.
Indicates whether the phone is using the IPv6
Alternate TFTP server.
Primary IPv6 Trivial File Transfer Protocol
(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
For information about the CTL or ITL file, see
the Cisco Unified Communications Manager
Security Guide. For information about
unlocking CTL files, see Unlock CTL and ITL
Files, on page 113.
