Configuring DHCP Snooped Packets Forwarding Support for DHCP Local Server
You can configure how DHCP local server handles DHCP snooped packets. Depending on the configuration, DHCP local server either forwards or drops the snooped packets it receives.
Table 1 indicates the action the router takes for DHCP local server snooped packets.
 | Note: Configured interfaces are those interfaces that have been configured with the group statement in the [edit system services dhcp-loal-server] hierarchy. Non-configured interfaces are those that are in the logical system/routing instance but have not been configured by the group statement. |
Table 1: Actions for DHCP Local Server Snooped Packets
forward-snooped-clients Configuration | Action on Configured Interfaces | Action on Non-Configured Interfaces |
|---|---|---|
forward-snooped-clients not configured | dropped | dropped |
all-interfaces | forwarded | forwarded |
configured-interfaces | forwarded | dropped |
non-configured-interfaces | dropped | forwarded |
To configure DHCP snooped packet forwarding for DHCP local server:
- Specify that you want to configure DHCP local server. [edit]user@host# edit system services dhcp-local-server
- Enable DHCP snooped packet forwarding for DHCP local server.[edit system services dhcp-local-server]user@host# edit forward-snooped-clients
- Specify the interfaces that are supported for snooped
packet forwarding. [edit system services dhcp-local-server forward-snooped-clients]user@host# set (all-interfaces | configured-interfaces | non-configured-interfaces)
For example, to configure DHCP local server to forward DHCP snooped packets on only configured interfaces:
