QUERY_MODE
Chapter 4 793
QUERY_MODE
QUERY_MODE returns information about modes that a local LU is
using, or has used, with partner LUs.
This verb can be used to obtain information about a specific partner
LU-mode combination or about multiple modes, and about modes for
which sessions are currently active or about all modes that have been
used, depending on the options used. This verb returns information
about current usage of the modes andLUs, not about their definition; use
QUERY_MODE_DEFINITION to obtain the definition of the modes and
LUs.
This verb must be issued to a running node.
