Command Usage
DHCPD is the daemon used by Linux to dynamically configure TCP/IP
information for client systems. To support DHCP option 66/67, you have to add
corresponding statements to the configuration file of DHCPD. Information on
how to complete this process are described in ““Downloading a Configuration
File Referenced by a DHCP Server” on page 69”.
By default, the parameters for DHCP option 66/67 are not carried by the reply
sent from the DHCP server. To ask for a DHCP reply with option 66/67, the client
can inform the server that it is interested in option 66/67 by sending a DHCP
request that includes a 'parameter request list' option. Besides this, the client
can also send a DHCP request that includes a 'vendor class identifier' option to
the server so that the DHCP server can identify the device, and determine what
information should be given to requesting device.
If ip and ipv6 dhcp dynamic-provision is disabled the default start-up
configuration file is used. If the start-up file is the Edgecore provided
Factory_Default_Config.cfg file, the default status is disabled.
If the address of VLAN 1 is configured as DHCP mode, the switch will check if it
has received any remote DHCP information every 5 seconds. If no information is
received, the switch DHCP client will keep sending a DHCP request once per
minute.
Dynamic provisioning will not be processed if the address mode of the switch is
user configured.
If the address mode has been restored from user configuration to be DHCP
mode, the procedures will be processed again.
