PERINTAH-PERINTAH DASAR "SHOW" PADA ROUTER
Perintah- Perintah singkat dan Penjelasan
1. show running-config
sh ru
Menampilkan konfigurasi yang sedang berjalan di RAM. Termasuk host name, passwords, interface IP address, routing protocol yang aktif, DHCP dan konfigurasi NAT. Dapat dijalankan di EXEC mode.show
2. startup-config
Sh st
menampilkan isi file konfigurasi yang tersimpan di NVRAM
Show version Sh v menampilkan informasi tentang versi software yang sekarang sedang jalan lengkap dengan informasi hardware dan devicenya.
3. show ip protocols
Sh ip p
memperlihatkan ip protokol routing yang telah dikonfigurasi dan sedang berjalan
4. show ip route
Sh ip ro
memperlihatkan konfigurasi routing
5. show interfaces
Sh in
Menunjukkan interface yg berjalan di router
6. show ip interface brief
Sh ip i b
Tinjauan semua antarmuka pada router
7. show protocols
Sh prot
menampilkan status interface baik secara global maupun khusus dari protokol layer 3 yang terkonfigurasi.
8. show cdp neighbors
Sh cd ne
Menampilkan ringkasan cdp perangkat tersambung
9. show sessions
Sh se
memperlihatkan sesi yang ada sekarang
10. show ssh
Sh ss
Menampilkan operasi status pengoperasian SSH
11. ping
P
memastikan apakah suatu komputer tertentu dalam suatu jaringan atau internet itu ada dan terhubung.
12. Traceroute
tr
menunjukkan rute yang dilewati paket untuk mencapai tujuan. Ini dilakukan dengan mengirim pesan Internet Control Message Protocol (ICMP) Echo Request Ke tujuan dengan nilai Time to Live yang semakin meningkat.
