Are you asking about "show local-host" command?If so the show local-host command lets you view the network states of local hosts. Local hosts are any hosts on the same subnet as an internal PIX Firewall interface (not the outside interface). Hosts beyond the next hop routers are not affected by this command.
This command lets you show the translation and connection slots for the local hosts, or stop all traffic on these hosts. This command provides information for hosts configured with the nat 0 command when normal translation and connection states may not apply.
The show local-host detail command displays more information about active xlates and connections.
