Command Usage
◆
Use this command without any keyword to restore the default setting.
◆
This command is used to identify the vendor class and configuration of the
switch to the DHCP server, which then uses this information to decide on how
to service the client or the type of information to return.
◆
The general framework for this DHCP option is set out in RFC 2132 (Option 60).
This information is used to convey configuration settings or other identification
information about a client, but the specific string to use should be supplied by
your service provider or network administrator. Options 60, 66 and 67
statements can be added to the server daemon's configuration file.
Table 147: Options 60, 66 and 67 Statements
Option
Keyword
60 vendor-class-identifier
66 tftp-server-name
67 bootfile-name
◆
By default, DHCP option 66/67 parameters are not carried in a DHCP server
reply. To ask for a DHCP reply with option 66/67 information, the DHCP client
request sent by this switch includes a "parameter request list" asking for this
information. Besides, the client request also includes a "vendor class identifier"
set by the ip dhcp client class-id command that allows the DHCP server to
identify the device, and select the appropriate configuration file for download.
This information is included in Option 55 and 124.
