The following RFCs (IETF Requests for Comment) describe BootP in detail:
ƒ RFC 951
ƒ RFC 1542
ƒ RFC 2132
Downloading of the image file with the VCX V7122/SIP uses TFTP. TFTP protocol is
described in RFC 906 and RFC 1350.
Although DHCP and BootP servers are very similar in operation, the DHCP server includes
some differences that might prevent its operation with BootP clients. However, many DHCP
servers, such as Windows NT DHCP server, are backward-compatible with BootP protocol
and can be used for VCX V7122/SIP configuration.
The BootP server is normally used to configure the VCX V7122/SIP initial
parameters. Once this information has been provided, the BootP server is no
longer needed. All parameters are stored in non-volatile memory and used when
the BootP server is not accessible. The BootP server is required again if, for
example, the VCX V7122/SIP IP address is to be changed.
Using BootP procedure, the following parameters are configured:
ƒ Boot and INI File Names – Optional. The Boot File Name field can contain one or two
file names: ram.cmp, to be used to download the application image, and Mediant.ini, to
be used for VCX V7122/SIP provisioning. Either one, two, or no file names can appear in
the Boot File Name field. To use both file names, use a semi-colon (;) separator (without
blank spaces) between the xxx.cmp and the yyy.ini files (for example,
ram.cmp;SIPgw.ini).
ƒ Local IP Address – IP address of your VCX V7122/SIP Gateway.
ƒ Gateway IP Address – If Default Gateway/Router is required; otherwise, enter 0.0.0.0
address.
ƒ Subnet Mask – Set the IP address and subnet mask fields to correspond with your
network IP address settings.
ƒ
TFTP Server IP address –TFTP and BootP servers are usually installed on the same
host. However, when using the 3Com BootP/TFTP Configuration Utility or Microsoft
DHCP server, it is possible to set the IP address of TFTP server (Boot server Host Name
field), and in this case BootP and TFTP servers can run from different hosts.
Configuring the TFTP Server
To configure the TFTP Server, follow these steps:
1
Set the default directory where the image file resides (C:\3Com\…).
2
Copy the Image file (such as ram.cmp to the TFTP default directory on your host PC.
