Cara Mencari Mac Address dan Ip Address di Cisco

Hari ini saya disibukkan untuk mencari Mac Address IP Camera yang terkoneksi ke Switch Cisco. Diswitch Cisco ternyata tidak diberi label atau deskripsi pada tiap portnya. IP Address, Mac Address, dan Port berapa? Itulah yang sering jadi pertanyaan kalau bekerja di jaringan komputer. Berikut sedikit perintah dalam command cisco yang digunakan dan trik untuk mencari mac address, IP address, dan port komputer.

Catatan:

  • Komputer client yang akan di trace harus dalam keadaan hidup dan terhubung ke jaringan

  • Menggunakan switch yang manageable.

Pertama, cara mencari mac address:

#show arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 10.32.16.58 38 001e.8cda.a615 ARPA Vlan16
Internet 10.32.10.32 90 0024.2188.1aec ARPA Vlan10
Internet 10.32.11.33 89 0022.6849.736a ARPA Vlan10
Internet 10.32.14.36 88 0022.684b.3589 ARPA Vlan14
Internet 10.3.1.8 0 0015.5d86.7d34 ARPA Vlan4

Cara mencari IP dengan mac address dan sebaliknya:

#show ip arp 0024.2182.2914
