네트워크 실습(9) vlan ㅠㅠ어렵

 

자 2교시 네트워킹 해볼게요..

오늘은 vlan이고 전에 설명했는데 반복 학습이니 또 설명합니다

즐감하세요 ㅋㅋ

바로 ㄱ

자 안녕하세요 네트워크 시간 2교시입니다.

오늘은 vlan알아볼게요 ㅋ

바로 ㄱㄱ

vlan 장점

- 부하분산 가능

- 대역폭 효율성 증가

- 시스템 부하 감사

- 보안 등등

 

vlan번호는 1-4094가 사용가능

1-005 사이인 것을 일반 vlan

1002-1005는 토큰링 및 FDDI용

즉 이더넷은 1-10001 까지

 

1006-4096은 확장판

근데 스위치마다 약간씩 다름

vlan별로 스패닝트리 동작하는것은 pvst 최대 128개

그리고 128개 초과시 mstp 나 루프없는 구조 설계로 완하가능

오늘은 내용이 쉬워요 한 10분안에 컷 될듯.

 

생성 및 부하분산 및 l3 라우팅까지 해볼게요

스패닝트리로인해 포트가 막혀있는데

vlan나눠주면 포트 활성화 및 독립 경로 생성

사용성 생산성 유지보수성 증가

자이렇게 실습을 했고

오늘 vlan에 대해서 간략히 알아봤어요

담 시간에는 vlan다음 내용을 하겠죠?기대하시고

수고링~!!
