Ping

Yap, ! Sederhana, tapi salah satu tool yang cukup membantu, terutama di Router.

Sekedar catetan, saya ngga’ akan nulis tentang ping itu sendiri, atau tips trobleshooting dengan ping di Cisco, atau penggunaan extended ping, atau debug ip packet, atau traceroute, atau dll. Cuman mau catet karakter-karakter yang keluar dari commnad ping.

- “.” = network server timed out
- “U” = destination unreachable
- “Q” = source quench (destination too busy)
- “M” = could not fragment
- “?” = unknown packet type
- “&” = packet lifetime exceeded

Soalnya pas troubleshoot koneksi antara dua aplikasi database yang sering drop nemuin hasil ping kayak gini:

ROUTER2811#ping 10.6.5.201 re 1000 size 5000
Type escape sequence to abort.
Sending 1000, 5000-byte ICMP Echos to 10.6.5.201, timeout is 2 seconds:
