.::: Bagaimana Mencari/Mentracert IP Dan Port Pada Switch/Router Cisco ? :::.

Contoh Studi kasus
Server dengan IP 10.10.10.100/TEGUH05SRV tidak diketahui lokasi secara fisik dan tetap bisa diping. dikarenakan perubahan struktur organisasi/ganti orang, biasanya letak server 10.10.10.100 tidak diketahui tertetak dimana ? bagaimana mentracert port dan switch yang terkoneksi ke server 10.10.10.100/TEGUH05SRV ?

langkah langkah

1. Telnet ke gateway Router
   sample Telnet 10.10.10.1

2. Check Address Resolution Protocol
   #show ip arp

3. Check Mac address ada di Router/port mana
   #show mac-address-table dynamic address

4. Check network, IP dan Interface port yang konek ke Router
   #show cdp neighbors

5. check konfigurasi port/interface
   #show running-config interface

Jawaban

server 10.10.10.100/TEGUH05SRV terletak dan terkoneksi ke switch TEGUH03 port Gi 1/38
