Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced for port helpers in Junos OS Release 17.2R1 for EX4300 switches.
Support for multiple server instances for a given port introduced in Junos OS Release 17.2
for MX Series routers.
Support for multiple server instances for a given port introduced in Junos OS Release
17.3R1 for EX9200 switches.
Specify the interface for monitoring and forwarding DNS or TFTP requests, or for
forwarding LAN broadcast traffic on a custom UDP port to a particular server as unicast
traffic.
When configuring port helpers, in releases prior to Junos OS Release 17.2, only one server
can be specified for a given port. For Junos OS Release 17.2 and later, multiple servers
can be specified for a given port at the global or interface-specific level. In this case, the
same packet, with the originator IP address and port requests, is forwarded to the different
configured servers; the payload of the UDP packet is not modified.
