Dynamic Host Configuration Protocol - Avaya 1110 Fundamentals

LLDP devices advertise their information by sending Type-Length-Value (TLV) messages to
their neighbors. The TLVs supported in the IP phones include:
• Basic Management TLV
• IEEE 802.1 Organizationally Specific TLV
• IEEE 802.3 Organizationally Specific TLV
• TIA Media Endpoint Discovery (LLDP-MED) TLV - The Telecommunications Industry
Association (TIA) has developed an extension to LLDP for VoIP networks. VoIP-related
extensions to 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

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, Avaya 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.
2001 IP Phone, 2002 IP Phone, and 2004 IP Phone, Avaya 2033 IP Conference Phone, and
Avaya 2050 IP Softphone can act as a DHCP client in one of two modes:
• partial DHCP mode
• full DHCP mode
The Avaya 2007 IP Deskphone, Avaya 1110 Series IP Deskphones, and Avaya 1200 Series
IP Deskphones act as a DHCP client in auto DHCP mode.
IP Phone parameters can be entered manually or obtained automatically. For more
information, see
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
