Port-based LAN broadcast traffic forwarding (port helpers) for multiple destination servers

We can configure port helpers on devices on a per-port basis for multiple destination servers. Port helpers are port-based filters that listen on configured UDP ports for incoming LAN broadcast traffic, and forward those packets to configured destination servers as unicast traffic. Configure port helper filters using the forwarding-options helpers port port-number configuration statement with any of the following scopes:

• Global - Match incoming broadcast traffic on any interface for a configured port, and forward the traffic to the configured server:
  set forwarding-options helpers port port-number server server-ip-address

• VLAN-specific - Match incoming broadcast traffic on an IRB interface for a configured port, and forward the traffic to the configured server:
  set forwarding-options helpers port port-number interface irb-interface-name server server-ip-address

• Interface-specific - Match incoming broadcast traffic on a Layer 3 interface for a configured port, and forward the traffic to the configured server:
  set forwarding-options helpers port port-number interface interface-name server server-ip-address
