How to Find / Mentracert Port Switch And The Used Server?
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
#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
