PERINTAH DASAR “SHOW” PADA ROUTER




Berikut penjelasan dari masing-masing perintah tersebut dan perintah singkatnya :
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.


Contoh penggunaan perintah show dalam packet tracer :
Router#sh ru
