●
Number of DHCP IP Addresses: Default = 200
This defines the number of sequential IP addresses, starting at the G150’s IP address,
that is allocated via DHCP on LAN1 and/or to dial in users. Addresses are only allocated
if the DHCP mode is set to Server or Dialin.
Note:
Note:
If the G150 is acting as the primary DHCP Server on the network (DHCP mode
set to Server or Dialin) on both the LAN1 and LAN2, Dial in users are allocated
their address from the LAN1 pool of addresses first.
4. If this is the last configuration being performed on Manager, click
Save. In the Sending
Config To dialog box, accept the selected save option and click OK. Otherwise, continue
making additional configuration updates and perform a Save when ready.
Using an External DHCP Server
If another device (other then the G150) is acting as the DHCP server for LAN1, the 176 option
needs to be added to that server. Avaya IP phones need the IP address of two H.323
Gatekeepers (Communication Manager and G150) and a TFTP server (for example a PC
running Manager). They do this by requesting the Option 176 setting from the DHCP server.
To configure Option 176 on the DHCP server, define the following in the string value field (this
sample string value is based on Windows 2000; the string format can vary depending on the
Operating System):
MCIPADD=xxx.xxx.xxx.xxx, www.www.www.www, MCPORT=1719,
TFTPSRVR=yyy.yyy.yyy.yyy, TFTPDIR=z
where:
●
xxx.xxx.xxx.xxx is the IP address of the Communication Manager.
●
www.www.www.www is the IP address of the G150’s LAN1 address.
●
yyy.yyy.yyy.yyy is the TFTP server IP address.
●
z is the directory on the TFTP server where the Avaya IP phones software files are
located. This information is not required if those files are in the TFTP server’s default
directory.
●
The maximum string length is 127 characters.
Refer to your DHCP server documentation for details of how to
●
Configure Option 176.
●
Ensure this option information is correctly supplied to the IP phones.
