ACL Deploying Guidelines for CCNA

CCNAs ေတြ ACL Deploying လုပ္တဲ႕အခါမွာ
• Standard ACL ကုိဘယ္မွာထားမလဲ ?
• Extended ACL ကိုဘယ္မွာထားမလဲ ?

ဆိုတာေလးကုိ Cisco ကဘယ္လုိ Recommend ေပးထားလဲဆိုတာသိထားရင္ အဆင္ေျပေျပ Configuration and Troubleshooting ပိုလုပ္လာႏုိင္ပါတယ္။

 

> Standard ACL ကုိတက္ႏုိင္သမၽွ Destination နဲ႔နီးနီးထားရပါမယ္။
Why ?
ဘာေၾကာင့္ဆုိေတာ႔ Standard က Source ကိုပဲၾကည့္ႏုိင္တာျဖစ္တဲ႔အတြက္
မလုိအပ္တဲ႔ Traffic ကုိ ပိတ္ျပီး Discard လုပ္ျပစ္တာမ်ိဳးမျဖစ္ရေအာင္ျဖစ္ပါတယ္။

> Extended ACL ကုိေတာ့ Source နဲ႔နီးနီးထားရပါမယ္။
Why ?
ဘာေၾကာင့္ဆုိေတာ႔ Extended က ပိုအေသးစိတ္ျပီး Source,Destination အျပင္ Ports နဲ႔ Protocol ကုိပါၾကည့္ႏုိင္တာျဖစ္တဲ႔အတြက္
Traffic ကုိေစာစာျဖတ္ျပီး Discard လုပ္ထားနိင္ရင္ မလုိအပ္တဲ႔ Traffic ေၾကာင့္ Bandwdith ကိုထိခို္က္မႈနညး္ေအာင္ျဖစ္ပါတယ္။

ဒီ Concept ရျပီဆိုရင္ ကၽြန္ေတာ္ထုတ္ထားတဲ႔ ေအာက္ကေမးခြန္းေလးကုိေျဖႏုိင္ပါျပီ။ အေျဖကေတာ့ မွန္မွာလုိ႔ ယံုၾကည္လုိ့ မေရးေတာ့ပါ။
😀 ေက်းဇူးပါ။
