Host Name Support; Selective Bootp; Vendor Specific Information; Table 6-2: Vendor Specific Information Field Tags - AudioCodes Mediant 2000 User Manual

When the Mediant 2000 detects that this optional parameter field is defined in
BootP, it initiates a TFTP process to load the file into the Mediant 2000. The new
configuration contained in the ini file can be stored in the Mediant 2000's integral
non-volatile memory. Whenever the Mediant 2000 is reset and no BootP reply is
sent to the board or the ini file name is missing in the BootP reply, the Mediant
2000 uses the previously stored ini file.
6.3.2

Host Name Support

From Boot software version 1.92 and above, if DHCP is selected, the Mediant 2000
registers a device-specific Host Name on the DNS server by defining the Host Name
field of the DHCP request. The host name is set to ACL_nnnnnnn, where nnnnnnn is
the serial number of the Mediant 2000 (the serial number is equal to the last 6 digits of
the MAC address converted from Hex to decimal). The DHCP server usually registers
this Host Name on the DNS server. This feature allows users to configure the Mediant
2000 via the Web Browser by providing the following URL: http://ACL_<serial
number> (instead of using the board's IP address).
6.3.3

Selective BootP

The Selective BootP mechanism, available from Boot version 1.92, allows the integral
BootP client to filter out unsolicited BootP replies. This can be beneficial for
environments where more than one BootP server is available and only one BootP
server is used to configure devices.
To activate this feature, add the command line switch -bs 1 to the Firmware File
Name field. When activated, the Mediant 2000 accepts only BootP replies
containing the text AUDC in the Vendor Specific Information field.
To deactivate, use -bs 0.
6.3.4

Vendor Specific Information

The Mediant 2000 uses the Vendor Specific Information field in the BootP payload to
provide device-related initial startup parameters (according to RFC 1533). This field is
not available in DHCP. The field is disabled by default.
To enable / disable this feature user can do one of the following:
a. Set the ini file parameter 'ExtBootPReqEnable' = 0 to disable, or 1 to enable.
b. Use the -be command line switch in the Boot file field in the BootP reply as
follows: ramxxx.cmp -be 0 to disable, or -be 1 to enable.
