公司有個switch既問題唔識解決

事情係咁,隔離area既同事有時會突然間連唔到出去(佢地隻switch),但係佢地既機可以互ping
正常情況下我個area係可以ping到曬佢地既機,但係當出事既時候,佢地既機就會ping唔到

當我將隻switch斷電再插就會無返事,起初以為switch問題但係換過隻都係咁(換過隻個隻係server房囉出黎,唔知有無暗病)但換完都係相同情況,佢地switch既機可以互ping但係就連唔到出去其他switch

我想問可以有咩方法係試佢有咩問題?因為老細唔想買野,如果買隻新返黎都係咁就大獲

咩SWITCH? Cisco?
try show processes cpu
睇下CPU loading有冇問題先

睇symptoms 似有loop, 因為如果looping一開始會冇咩事,
但當loop番一段時間個cpu loading太勁就出事, 所以熄左開番又冇事
換左switch same config same topology一樣出事

係唔係條LAN CABLE有事啊?

area內可以互通,咁另一面果隻switch又點?
或者轉port試囉,有時壞某幾個port都唔奇

1. access the two switches to see any failure singal color
2. try to change port
3. any access rule change ?

Other questions,
Is your pc in the same VLan and subnet of that area?
When problem raise, is the pc can ping to gateway?

The other switch have any port security setting?

Check 吓隔籬 (唔係『隔離』) 個 area 有無人裝咗啲非公司嘅網絡裝置,且有 dhcp server 功能的。嗰個裝置隻 dhcp server 派咗 ip 比隔籬個 area 所以隔籬個 area 就『隔離』咗。

Setup 左Port Security?
