DHCP

Comply with the DHCP standard by setting DHCPSTD to “1”, or

Continue to use its IP Address after the DHCP lease expires by setting DHCPSTD to “0”.

The latter case is the default. If the default is invoked, after the DHCP lease expires the telephone sends an ARP Request for its own IP Address every five seconds.

The request continues either forever, or until the phone receives an ARP Reply. After receiving an ARP Reply, the telephone displays an error message, sets its IP Address to 0.0.0.0, and attempts to contact the DHCP server again.

-Option 52 - Overload Option, if desired. If this option is received in a message, the telephone interprets the sname and file fields in accordance with RFC 2132, Section 9.3.

-Option 58 - DHCP lease renew time, if desired.

-Option 59 - DHCP lease rebind time, if desired.

-Option 66 - TFTP Server Name.

Note:

Microsoft DHCP servers support only dotted-decimal format for file server addresses, not symbolic names. Option 66 need not be used if the TFTP server is identified in the Site Specific Option Number string (Option 176), or if HTTP is to be used exclusively instead of TFTP. However, to simplify configuration, we recommend that you use Option 66 if you are using TFTP. If you use both Option 66 and Option 176 to identify TFTP servers, the value(s) in Option 176 overrides the value(s) in Option 66.

-A 4600 Series IP Telephone-specific DHCP option specifying information such as TFTP server and Avaya Media Server Gatekeeper IP Addresses. Use the Site-Specific Option Number (SSON) at #176. You can set this option’s value, for example, to either of the following strings:

MCIPADD=xxx.xxx.xxx.xxx,MCPORT=yyyy,TFTPDIR=<path>,TFTPSRVR= zzz.zzz.zzz.zzz

OR

MCIPADD={list of DNS names}, MCPORT=yyyy, TFTPDIR=<path>, TFTPSRVR= {list of DNS names}

Note:

List the TFTPDIR value before the TFTPSRVR value, if the latter is specified in the SSON.

Note:

Some DHCP applications limit the length of Option 176 to 247 characters.
