Before installing each DHCP server, obtain the following required network information:
●
Gateway/router IP addresses
●
TFTP server IP addresses
●
Subnet mask
●
Media controller (C-LAN circuit pack) IP addresses
●
Media controller (C-LAN circuit pack) port
●
TFTP server path
●
Telephone IP address range
- From:
- To:
●
DNS server addresses
The TFTP server file path is the “root” directory that is used for all transfers by the server. This is
the default directory which all files will be uploaded to, or downloaded from. In configurations
where the upgrade script and the application files are in the default directory, TFTP server path
should not be used.
Avaya can use a special option, Option 176, to pass these values. Avaya has done significant
testing of and had good success with Option 176 on the Microsoft Windows 2000 DHCP server
and the ISC DHCP server (common on Linux and Unix platforms). Results from other DHCP
servers may vary. A typical Option 176 string looks like the following string:
“MCIPADD=#.#.#.#,MCPORT=1719,TFTPSRVR=#.#.#.#,L2Q=1,L2QVLAN=0”
where
●
MCIPADD is the IP address of the C-LAN
●
MCPORT is the UDP port that is used for telephone registration
●
TFTPSRVR is the TFTP server that the telephone uses to look for firmware and
configuration upgrades
●
L2Q is 802.1Q. 1 is on, 0 is off
●
L2QVLAN is the VLAN that the telephone uses. Vlan ID 0 is a special vlan ID that tells the
next Layer 2 switch to replace the 0 tag with the native vlan ID on that ingress port.
