stp instance 2 priority 8192
cluster enable
ntdp enable
ndp enable
stp region-configuration
region-name huawei
revision-level 1
instance 1 vlan 10 設定例項1對映的vlan
instance 2 vlan 20
active region-configuration 啟用

交換機交換機
交換機。常常聽人說交換機 路由器。什麼是交換機？為什麼叫交換機？交換什麼？交換機是不是就是路由器？這二者有什麼區別？這是我的疑問。沒辦法，基礎沒打好。一 什麼是交換機 交換機是這麼一種裝置 將網路分成若干小段，以解決網路擁堵，降低出錯，提高傳輸效率。為什麼分成若干小段可以提高傳輸效率呢？這涉及到網路...
接入交換機，匯聚交換機，核心交換機
通常將網路中直接面向使用者連線或訪問網路的部分稱為接入層，將位於接入層和核心層之間的部分稱為分布層或匯聚層。接入交換機一般用於直接連線電腦，匯聚交換機一般用於樓宇間。匯聚相對於乙個區域性或重要的中轉站，核心相當於乙個出口或總彙總。原來定義的匯聚層的目的是為了減少核心的負擔,將本地資料交換機流量在本地...
交換機分布快取 核心交換機PK普通交換機
核心交換機我們平時提的挺多，那麼他與普通交換機到底有什麼區別的呢，今天我們一起來了解下。一 埠的區別 普通交換機埠數量一般為24 48個，網口大部分為千兆乙太網或者百兆乙太網口，主要功能用於接入使用者資料或者匯聚一些接入層的交換機資料，這種交換機最多可以配置vlan簡單路由協議和一些簡單的snmp等...
