NAME

llttest - Low Latency Transport (LLT) Protocol test utility

SYNOPSIS

llttest -p port [-v] [-s size]

DESCRIPTION

The llttest utility tests the connectivity of the LLT protocol between the systems in a cluster. It uses the user-level STREAMS interface to the LLT stack. llttest has an interactive interface that facilitates the sending and receiving of LLT packets between systems. The -p1 option is required to select an LLT port ( llttest operates only on one port per instance).
