Chapter 5 Configuring and Managing the Cisco Unified IP Phone
Configuring the Cisco Unified IP Phone
IPv6 Load Server — Leave blank. Indicates that the phone will use an alternative IPv6
server to obtain firmware loads and upgrades, rather
than the defined TFTP server. This option enables
you to indicate a local IPv6 server to be used for
firmware upgrades, which can assist in reducing
install times, particularly for upgrades over a WAN.
Enter the hostname or the IPv6 address (using
standard IPv6 addressing format) of the server. The
indicated server must be running TFTP services and
have the load file in the TFTP path. If the load file is
not found, the load will not install. The phone will
not be redirected to the TFTP server. If this field is
left blank, the phone will use the designated TFTP
server to obtain its load files and upgrades.
Maximum length: 256.
IPv6 Log Server — Leave blank. Specifies an IPv6 address and port of a remote
system where log messages are sent. The phone
sends the log data to the IPv6 server specified in this
field. However, as of Unified CM release 7.1(2), the
log viewer application cannot receive log data that
gets sent to an IPv6 address. You can view the log
data by using a network packet sniffer. Maximum
length: 256.
802.1x Authentication — User Controlled. Specifies the 802.1x authentication feature status.
Detect Unified CM
Connection Failure Yes Leave the default setting
(Normal). Determines the sensitivity that the phone has for
detecting a connection failure to Cisco Unified
Communications Manager (Unified CM), which is
the first step before device failover to a backup
Unified CM/SRST occurs.
Valid values specify Normal (detection of a Unified
CM connection failure occurs at the standard system
rate) or Delayed (detection of a Unified CM
connection failover occurs approximately four times
slower than Normal).
For faster recognition of a Unified CM connection
failure, choose Normal. If you prefer failover to be
delayed slightly to give the connection the
opportunity to reestablish, choose Delayed. Note
that the precise time difference between Normal and
Delayed connection failure detection depends on
many variables that are constantly changing.
