Release Information Statement introduced in Junos OS Release 10.4.
Statement introduced in Junos OS Release 12.3R2 for EX Series switches.
Support at the [edit forwarding-options dhcp-relay dhcpv6] hierarchy level introduced in
Junos OS Release 15.1X53-D56 for EX Series switches and Junos OS Release 17.1R1.
Description Configure how DHCP relay agent filters and handles DHCP snooped packets on the
specified interfaces. The router or switch determines the DHCP snooping action to perform
based on a combination of the forward-snooped-clients configuration and the
configuration of either the allow-snooped-clients statement or the
no-allow-snooped-clients statement.
The router (or switch) also uses this statement to determine how to handle snooped
BOOTREPLY packets received on non-configured interfaces.
Options all-interfaces—Perform the action on all interfaces.
Default: On EX Series switches, the action is performed on all interfaces by default.
configured-interfaces—Perform the action only on interfaces that are configured as part
of an interface group.
non-configured-interfaces—Perform the action only on interfaces that are not part of a
group.
Required Privilege
Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
