Grouping Interfaces with Common DHCP Configurations

The extended DHCP applications enable you to group together a set of interfaces and apply a common DHCP configuration to the named interface group.

To configure an interface group, use the group statement.




group group-name {



authentication {

password password-string;



username-include {

circuit-type;

delimiter delimiter-character;

domain-name domain-name-string;

logical-system-name;

mac-address;

option-60;

option-82 <circuit-id>
<remote-id>;

routing-instance-name;

user-prefix user-prefix-string;
}


}


interface interface-name <upto upto-interface-name> <exclude>;
}

You can specify the names of one or more interfaces on which the extended DHCP application is enabled. You can repeat the interface interface-name statement to specify multiple interfaces within a group, but you cannot specify the same interface in more than one group. For example:



group boston {
interface 192.168.10.1;
interface 192.168.15.5;
}

You can use the upto option to specify a range of interfaces on which the extended DHCP application is enabled. For example:



group quebec {
interface 192.168.10.1 upto 192.168.10.255;
}

You can use the exclude option to exclude a specific interface or a specified range of interfaces from the group. For example:



group paris {
interface 192.168.100.1 exclude;
interface 192.168.100.100 upto 192.168.100.125 exclude;
}
