You cannot
telnet to the
terminal. A
message is
displayed,
indicating that
the number of
connections to
the terminal
has reached the
upper limit.
The number of connections to the terminal
has reached five.
Disconnect some of the
Telnet connections.
If the interval between two connection
attempts is less than 10 minutes, these two
attempts are considered as two separate
connections to the terminal. For example,
if multiple clients telnet to the terminal,
the number of connections will reach five.
If a client has connected to the terminal
and if an exception occurs on the network,
the client disconnects from the terminal.
After the network is recovered (within 10
minutes), the Telnet resources, however,
may not be released at that time.
If no data is transmitted on
a Telnet connection for 10
minutes, the connection
will be disconnected
automatically. Wait for 10
minutes or more until
inactive Telnet connections
get disconnected, and then
telnet to the terminal.
