user@host# edit forward-snooped-clients
3. Specify the interfaces that are supported for snooped packet forwarding.
[edit forwarding-options dhcp-relay forward-snooped-clients]
user@host# set (all-interfaces | configured-interfaces | non-configured-interfaces)
For example, to configure DHCP relay agent to forward DHCP snooped packets on only
configured interfaces:
[edit]
forwarding-options {
dhcp-relay {
forward-snooped-clients configured-interfaces;
}
}

Configuring Named Server Groups
You can configure a named group of DHCP servers for use by the extended DHCP relay
agent on the router or switch.
You specify the name of the DHCP server group and the IP addresses of one or more
DHCP servers that belong to this group. You can configure a maximum of five IP addresses
per named server group.
To configure a named server group:
1. Specify the name of the server group.
[edit forwarding-options dhcp-relay]
user@host# set server-group myServerGroup
2. Add the IP addresses of the DHCP servers belonging to the group.
[edit forwarding-options dhcp-relay server-group myServerGroup]
user@host# set 192.168.100.50
user@host# set 192.168.100.75
