For the Perforce Proxy and replica servers, the name and port number of the target Perforce server (that is, the Perforce server for which P4P acts as a proxy; for a replica or edge server, the upstream master or commit server from which it retrieves its data, and towards which changelists, if applicable, are forwarded.)

The format of P4TARGET on is host:port, or port by itself if both the Perforce server and the proxy, replica, or edge server are running on the same host.

Port numbers must be in the range 1024 through 32767.

For more about replicas, edge servers, and the Perforce Proxy, see Perforce Server Administrator's Guide: Multi-site Deployment.
