[c-nsp] Cisco IOS XR event manager run

[Mohammad Khalil]

I tried the below script


array set arr_einfo [event_reqinfo]

if [catch {cli_open} result] {
    error $result $errorInfo
} else {
    array set cli1 $result
}

if [catch {cli_write $cli1(fd) "run attach 0/1/CPU0"} _cli_result] {
    error $_cli_result $errorInfo
}

if [catch {cli_read_pattern $cli1(fd) "#"} _cli_result] {
    error $_cli_result $errorInfo
}

if [catch {cli_write $cli1(fd) "show_nat44_stats"} _cli_result] {
    error $_cli_result $errorInfo
}

if [catch {cli_read_pattern $cli1(fd) "#"} _cli_result] {
    error $_cli_result $errorInfo
}

set output $_cli_result

if [catch {cli_exec $cli1(fd) "exit"} _cli_result] {
    error $_cli_result $errorInfo
}
puts "$_cli_result"}

# Close open cli before exit.
catch {cli_close $cli1(fd) $cli1(tty_id)} result

But nothing appeared on the screen
