Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Device Configuration Menu
Security Configuration Menu
The Security Configuration menu that you access from the Device Configuration menu displays settings
that relate to security for phone. It also provides access to the Trust List menu. This menu indicates if
the CTL or ITL file is installed on the phone.
Table 4-18 describes the options on the Security Configuration menu.
Note The phone also has a Security Configuration menu that you access directly from the Settings menu. For
information about the security options on that menu, see Security Configuration Menu, page 4-35.
Span to PC Port Indicates whether the phone forwards packets transmitted and
received on the network port to the access port.
Enable this option if an application that requires monitoring of
the phone’s traffic is being run on the access port. These
applications include monitoring and recording applications
(common in call center environments) and network packet
capture tools that are used for diagnostic purposes.
From Cisco Unified Communications
Manager Administration, choose
Device > Phone > Phone
Configuration.

Option Description To Change
PC Port
Disabled
Indicates whether the access port on the phone is enabled
or disabled.
Note If disabled, video will not work on this phone,
even if video is enabled.
From Cisco Unified Communications Manager
Administration, choose Device > Phone >
Phone Configuration.
GARP Enabled Indicates whether the phone learns MAC addresses from
Gratuitous Address Resolution Protocol (ARP)
responses. Disabling the phone’s ability to accept
Gratuitous ARP will prevent applications that use this
mechanism to monitor and record voice streams from
working. If voice monitoring is not desired, set this
option to No (disabled).
From Cisco Unified Communications Manager
Administration, choose Device > Phone >
Phone Configuration.
Voice VLAN
Enabled
Indicates if the phone allows a device attached to the
access port to access the Voice VLAN:
• Setting this option to No (disabled) prevents the
attached PC from sending and receiving data on the
Voice VLAN. This setting also prevents the PC from
receiving data sent and received by the phone.
• Set this setting to Yes (enabled) if an application that
requires monitoring of the phone traffic is running
on the PC. These applications include monitoring
and recording applications and network
monitoring software.
From Cisco Unified Communications Manager
Administration, choose Device > Phone >
Phone Configuration.
