◆
If the switch does not receive a DHCP response prior to completing the
bootup process, it will continue to send a DHCP client request once a
minute. These requests will only be terminated if the switch’s address is
manually configured, but will resume if the address mode is set back to
DHCP.
To successfully transmit a bootup configuration file to the switch the DHCP
daemon (using a Linux based system for this example) must be configured
with the following information:
◆
Options 60, 66 and 67 statements can be added to the daemon’s
configuration file.
◆
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” 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.
The following configuration example is provided for a Linux-based DHCP
daemon (dhcpd.conf file). In the “Vendor class” section, the server will
always send Option 66 and 67 to tell switch to download the “test”
configuration file from server 192.168.255.101.
