Note. The comments embedded in snmpfsh and the other files used by managers supporting
UDP and IPC use the term “local” to mean IPC and the term “remote” to mean UDP.
version The SNMP version being supported.
local_flag An indication of whether to use UDP or IPC communication.
host_name The name of a NonStop Kernel system; used for IPC
communication.
