Library /sys$common/syshlp/net$configure_help.hlb NET$CONFIGURE Help, eshello_timer  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Default ESHello Timer attribute determines the interval, in
    seconds,  when the ES sends out its hello.

    This interval multiplied by three is the amount of time the other end
    of  a routing adjacency will wait before determining that this system
    is no  longer able to accept connections.
