ip dhcp-server icmp-probe
Description
With this command, you enable the "Probe address with ICMP Echo before offer" function.
The DHCP server checks whether or not the IPv4 address has already been assigned. If no
reply is received, the DHCP server can assign the IPv4 address.
You are in the Global Configuration mode.
The command prompt is as follows:
cli(config)#
Call the command without parameter assignment:
ip dhcp-server icmp-probe
The function is enabled.
You disable the function with the no ip dhcp-server icmp-probe command.
ip dhcp-server pool
Description
With this command, you have two options of changing to the DHCPPOOL configuration
mode and to assign an interface to the IPv4 address band.
1. If you call the command
ip dhcp-server pool with the parameter pool-id (1-5), you
change directly to the DHCPPOOL configuration mode.
If the ID of the addressed IPv4 address band does not yet exist, it is first created and
assigned to an interface by default. You then configure the interface and the other
settings in the DHCPPOOL configuration mode.
2. If you call the command
ip dhcp-server pool with the parameter show-interface-options,
you call a variant of the command. With this variant, you assign an interface to the IPv4
address band and change to the DHCPPOOL configuration mode. If the ID of the
address IPv4 address band does not yet exist, it will be created. You then configure the
other settings in the DHCPPOOL configuration mode.
