HP Comware 5 Debug Manual Vol 2

Field
Description
Forward mode
Forwarding modes of LB outbound packets:
• NAT.
• Direct Routing.
• Firewall Forwarding.
Prompt: Sending the packet to the real
server rserveripaddr
This prompt is displayed only when the forwarding mode is
Direct Routing or Firewall Forwarding.
The destination address in these two modes cannot identify the
device or server that processes the packets. Therefore, this
prompt is needed to identify the device or server that processes
the packets.
Examples
# Enable all types of LB debugging. The output in this example was created when the following
conditions exist:
•
The client is connected to the real service server through an LB device.
•
The virtual service forwarding type is NAT.
•
The client sends a connection request to the virtual service on the LB.
