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 XR software EXEC session that allocates a Cisco IOS XR
software vty. The vty remains in use until the cli_close routine is called. Vtys are allocated from the pool
of vtys that are configured using the line vty vty-pool CLI configuration command. Be aware that the
cli_open routine fails when two or fewer vtys are available, preserving the remaining vtys for Telnet use.
