interface vlan number—(Optional) Clears active translations by the VLAN

state static—(Optional) Clears active translations by the state.
•
portmap—(Optional) Clears active translations by the port map.

If you configured redundancy, then you need to explicitly clear Xlates on both the
active and the standby ACEs. Clearing Xlates on the active appliance alone will
leave the standby appliance's Xlates at the old mappings.
For example, to clear all static translations, enter:
host1/Admin# clear xlate state static
The following sections show typical scenarios that use dynamic and static NAT
solutions:

The following SNAT configuration example shows the commands that you use to
configure dynamic NAT and PAT on your ACE. In this SNAT example, packets
that ingress the ACE from the 192.168.12.0 network are translated to one of the
IP addresses in the NAT pool defined on VLAN 200 by the nat-pool command.
The pat keyword indicates that ports higher than 1024 are also translated.
If you are operating the ACE in one-arm mode, omit interface VLAN 100 and
configure the service policy on interface VLAN 200.
