cli_open
Allocates a vty, creates an EXEC command-line interface (CLI) session, and connects the vty to a channel
handler. Returns an array including the channel handler.
Note Each call to cli_open initiates a Cisco IOS EXEC session that allocates a Cisco IOS vty line. The vty
remains in use until the cli_close routine is called. The vty lines are allocated from the pool of vty lines
that are configured using the line vty CLI configuration command. EEM will use a vty line when a vty
line is not being used by EEM and there are available vty lines. EEM will also use a vty line when EEM
is already using a vty line and there are three or more vty lines available. Be aware that the connection
will fail when fewer than three vty lines are available, preserving the remaining vty lines for Telnet use
