Examples
# Enable UDP helper packet debugging.
<Sysname> terminal debugging
<Sysname> terminal monitor
<Sysname> debugging udp-helper packet
# Enable UDP helper.
<Sysname> system-view
[Sysname] udp-helper enable
# Configure UDP helper to forward broadcast packets with the UDP destination port 520 to the
destination server 2.2.2.2.
[Sysname] udp-helper port 520
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] udp-helper server 2.2.2.2
Output similar to the following example is generated when a UDP packet with the destination port 520
arrives at Ethernet 1/1:
*Aug 11 08:20:46:00 2005 Sysname UDPH/7/UDPHelper_Pkt:
Dest Ip(1.1.1.255) Source Ip(1.1.1.5) Dest Port(520)
Prompt: Intercept a UDP packet.
// UDP helper received a UDP packet.
*Aug 11 08:20:46:01 2005 Sysname UDPH/7/UDPHelper_Pkt:
Dest Ip(1.1.1.255) Source Ip(1.1.1.5) Dest Port(520)
Prompt: Copy the packet and send it to the UDP module.
// UDP helper copied the UDP packet and sent it to the UDP module.
*Aug 11 08:20:46:02 2005 Sysname UDPH/7/UDPHelper_Pkt:
