Di bulan yang mulai menua ini, selain dompet udah mulai kering tenaga pun d buat kering karena Tugas Jaringan Komputer 3 yang pertama ini :D. Posting kali ini membahas mengenai Perintah Dasar "Show" Pada Router. Sebelum jalan lebih lanjut kita kenali dulu perintah "show" apa saja yang ada pada router, cekibrot.

PERINTAH PENUH	PERINTAH SINGKAT	MAKSUD PERINTAH
Show running-config	sh ru	Digunakan untuk menampilkan konfigurasi yang sedang berjalan di RAM. Termasuk host name, passwords, interface IP addresses, routing protocol yang aktif, DHCP dan konfigurasi NAT. Dapat dijalankan di EXEC mode.
Show startup-config	sh st	Digunakan untuk menampilkan isi file konfigurasi yang tersimpan di NVRAM mulai dari Host Name, Passwords, Interface IP Addresses, Routing Protocol yang aktif, DHCP dan konfigurasi NAT.
Show version	sh v	Digunakan untuk menampilkan informasi tentang versi software yang sekarang sedang jalan lengkap dengan informasi hardware dan devicenya.
Show ip protocols	sh ip p	Berguna untuk memperlihatkan status interface IP secara global maupun khusus dari IP protokol routing yang telah dikonfigurasi dan sedang berjalan.
Show ip route	sh ip ro	Menampilkan konfirmasi pada Router yang telah di authentikasi oleh Router lain dan telah mampu memperoleh rute dari Router lainnya, selain itu juga digunakan untuk mengetahui konfigurasi IP yang dilakukan baik secara global maupun secara khusus.
Show interfaces	sh int	Digunakan untuk menampilkan statistic semua interface router  mulai dari FastEthernet dan Serial. Untuk menampilkan statistic interface tertentu, menggunakan perintah show interfaces diikuti dengan nomor port/slot interface, contoh : Router#show interfaces serial 2/0
Show ip interface brief	sh  ip int br	Digunakan untuk menampilkan Konfigurasi pada interface yang terhubung pada router. Mulai dari konfigurasi yang sedang berjalan maupun yang konfigurasi yang tidak berjalan (belum terkonfigurasi). Pada perintah ini kita dibawa untuk mengetahui : Interface, IP-Address, Method, Status, Protocol.
Show protocols	sh prot	Menampilkan status interface baik secara global maupun khusus dari protokol layer 3 yang terkonfigurasi.
Show cdp neighbors	sh cdp ne	Digunakan untuk mengetahui Capability Codes perangkat yang tersambung, yang meliputi : R (IYN), T (Trans Bridge), B (Source Route Bridge), S (Switch), H (Host), I (IGMP), r (Repeater), P (Phone). Selain itu juga digunakan untuk mengetahui Device ID diantaranya : Local Intrfce, Holdtme, Capability, Platform, Port ID.
Show sessions	sh ses	Untuk mengetahui koneksi yang sedang berjalan (koneksi yang di buka).
Show ssh	sh ss	Digunakan untuk melakukan koneksi dengan server SSHv2 dan SSHv1.
Ping	p	Digunakan untuk melakukan / melihat koneksi antar jaringan yang sedang berhubungan. Perintah ping harus diikuti address or hostname. Contoh : ping 192.168.1.1
Traceroute	tra	Perintah untuk menunjukkan rute yang dilewati paket untuk mencapai tujuan dengan mengirim pesan Internet Control Message Protocol (ICMP) Echo Request Ke tujuan dengan nilai Time to Live yang semakin meningkat.. Rute yang ditampilkan adalah daftar interface router (yang paling dekat dengan host) yang terdapat pada jalur antara host dan tujuan.

Berikut ini merupakan contoh hasil yang keluar dalam penggunaan perintah show di atas dengan menggunakan media Packet Tracer sebagai simulatornya.
