424 Features

LLDP, known as LLDP-Media Endpoint Discovery (LLDP-MED)

enables media devices to transmit and receive media related

information.

The 802.1ab feature provides automatic configuration of the IP Phone

network policy parameters, such as VLAN ID, as well as, automatic

detection of misconfigurations, such as Duplex discrepancies.

The 802.1ab feature is enabled by default. However, you can disable the

feature during manual configuration.

For information about 802.1ab configuration, see “Provisioning the IP

Phones” (page 491).

Dynamic Host Conﬁguration Protocol

This section provides information about Dynamic Host Configuration

Protocol (DHCP) server installation, configuration, and operation.

If you are not familiar with DHCP, Nortel recommends reading Request for

Comments (RFC) 2131 "Dynamic Host Configuration Protocol", RFC 1533

"DHCP Options and BOOTP Vendor Extensions", and the Help manual for

the DHCP server on the host.

IP Phones

IP Phones function as a telephone to the Meridian 1 and CS 1000

systems. The IP Phone encodes voice as binary data and packetizes the

data for transmission over an IP network to the Call Server, to the Terminal

Proxy Server (TPS), or to another IP Phone.

IP Phone 2001, IP Phone 2002, and IP Phone 2004, IP Audio Conference

Phone 2033, and IP Softphone 2050 can act as a DHCP client in one of

two modes:

•

partial DHCP mode

•

full DHCP mode

The IP Phone 2007, IP Phones 1110 Series, and IP Phones 1200 Series

act as a DHCP client in auto DHCP mode.

IP Phone parameters can be entered manually or obtained automatically.

For more information, see “Provisioning the IP Phones” (page 491).

All the IP Phone configuration parameters can be entered manually. Each

IP Phone requires the network configuration parameters, Connect Server

parameters, IP Telephony node ID, and Virtual TN. If there are a number

of IP Phones to configure, manual configuration is time-consuming and
