Packet Flow Explore

This chapter covers how to use the packet flow explore feature.

40.1 Packet Flow Explore

Use this to get a clear picture on how the NXC determines where to forward a packet and how to change the source IP address of the packet according to your current settings. This function provides you a summary of all your routing and SNAT settings and helps troubleshoot the related problems.

40.2 Packet Flow Explore Commands

The following table lists the commands that you can use to have the NXC display routing and SNAT related settings.

Table 151 Packet Flow Explore Commands

	packets. Once a packet matches the criteria of a routing rule, the NXC

	checking.
show system snat nat-1-1	Displays activated NAT rules which use SNAT.
show system snat nat-loopback	Displays activated NAT rules which use SNAT with NAT loopback
