The pmap_udp state engine is used for the UDP portmap protocol used by UDP services. It monitors the UDP portmap requests and responses and builds a table of hosts and ports to RPC service mappings. Normally, a service definition for a UDP RPC service requires both a pmap_udp and a rpc_udp state engine entry. The discriminator for the pmap_udp state engine is the RPC program number of the service.
The pmap_udp state engine has the following parameters:
Response timeout in seconds - This parameter 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 or 1 hour)
