The following configuration example shows those sections of the running
configuration related to the commands necessary to configure SNAT (dynamic
NAT) with cookie load balancing. Any source host that sends traffic to the VIP
20.11.0.100 is translated to one of the free addresses in the NAT pool in the range
30.11.100.1 to 30.11.200.1, inclusive. If you want to use PAT instead of NAT,
replace "nat dynamic 1 vlan 2021" with "nat dynamic 2 vlan 2021" in the
L7SLBCookie policy map.
