평소에는 제가 한드림넷 스위치만 접속해서 정보를 본 적이 많이 있습니다.

그런데 운이 좋게도 시스코 스위치 CLI 접속해볼 기회가 있어서 접속해서 arp정보를 긁어왔는데요

일단 한드림넷 스위치에서 mds arp table 명령어를 사용해서 정보를 읽어올 때는

해당 IP와 mac주소 그리고 스위치 연결된 포트 넘버까지 보여줍니다.

헌데 시스코 스위치에서 show arp 치면 인터페이스 상에 IP와 MAC주소를

보여주더라구요.

그래서 저는 한드림넷 스위치 명령어를 생각해서 각 포트에 접속되어 있는

IP정보를 보려고 show arp 내에 명령어를 여러가지 넣어봤습니다만 안나오더라구요.

마지막에 사수가 가르쳐준 show mac address-table 명령어를 치니까

시스코 스위치 각 포트에 접속해 있는 MAC주소 값은 나오는데 IP는 안나오던데

이게 단순히 MAC address명령어를 사용해서 table값을 불러와서 그런 것 같은데요.

ip arp table 명령어가 따로있는데 제가 잘 몰라서 장비마다 시스코 스위치에 접속한 

ip정보를 못본 것인가하는 의문이 들어서요.


혹시 시스코 스위치에 관련해서 잘 아시는 분 계시면 좀 알려주십시오~
