code
Code can be a number between 1 and 61 or a keyword. Use the command
dhcp
list
definedoptions
to list the codes and keywords.
Examples:
dhcp clear valueoption 4
dhcp clear valueoption 192.168.254.0 7
dhcp clear valueoption 192.168.254.2 gateway
DHCP DEL
This command is used to delete a subnetwork lease, a specific client lease, or a code.
net
IP address of the subnetwork lease in the format of 4 decimals separated by periods.
ipaddr
IP address of the client lease in the format of 4 decimals separated by periods.
code
The code is user-defined and can be a number between 128 to 254 or a keyword.
Examples:
dhcp del 192.168.254.0
(
deletes this subnetwork
)
dhcp del 192.168.254.31
(deletes this client lease)
dhcp del 128
(deletes this option with code 128)
DHCP DISABLE
This command is used to disable a subnetwork or a client lease.
all Disables all subnets.
net
IP address of the subnetwork lease in the format of 4 decimals separated by periods.
ipaddr
IP address of the client lease in the format of 4 decimals separated by periods.
Examples:
dhcp disable 192.168.254.0
dhcp disable 192.168.254.17
DHCP ENABLE
This command is used to enable a subnetwork or a client lease.
all Enables all subnets.
