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 whether 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.
