Cisco IP Phone 6800 Series Multiplatform Phones Administration Guide

Default Description
On Allows you to enable or disable Cisco Discovery Protocol (CDP).
CDP is a device-discovery protocol that runs on all Cisco
manufactured equipment.
Using CDP, a device can advertise its existence to other devices
and receive information about other devices in the network.
On Allows you to enable or disable LLDP-MED.
LLDAP-MED enables the phone to advertise itself to devices
that use the discovery protocol.
3 seconds Allows you to set a value that causes a delay for the switch to get
to the forwarding state before the phone will send out the first
LLDP-MED packet. The default delay is 3 seconds. For
configuration of some switches, you might need to increase this
value to a higher value for LLDP-MED to work. Configuring a
delay can be important for networks that use the Spanning Tree
Protocol.
Off Allows you to enable or disable VLAN.
Allows you to enter a VLAN ID when you use VLAN without
CDP or LLDP. When you use a VLAN with CDP or LLDP, that
associated VLAN takes precedent over the manual entered VLAN
ID.
1 Allows you to enter a VLAN ID for the IP phone when you use
a VLAN without CDP (VLAN enabled and CDP disabled). Note
that only voice packets are tagged with the VLAN ID. Do not
use 1 for the VLAN ID. If VLAN ID is 1, you cannot tag voice
packets with the VLAN ID.
1 Value of the VLAN ID that is used to tag communications from
the PC port on the phone.
The phone tags all the untagged frames coming from the PC (it
will not tag frames with an existing tag).
Valid values are: 0-4095. Default: 0.
On Adds the ability to port mirror on the PC port. When enabled,
you can see the packets on the phone. Select On to enable PC
port mirroring and select No to disable it.
