The pmap_tcp state engine is used for the TCP portmap protocol used by TCP RPC services. It monitors the TCP portmap requests and responses and builds a table of hosts and ports to RPC service mappings. Normally, a service definition for a TCP RPC service requires both a pmap_tcp and a rcp_tcp state engine entry. The discriminator for the pmap_tcp state engine is the RPC program number of the service.
The pmap_tcp state engine has the following parameters:
Response timeout in seconds - Specifies the time to wait for portmap responses. (Default = 60 seconds)
Lifetime of portmap mapping entries in seconds - -1 specifies an infinite lifetime (default = 3600 seconds).
