Cisco Small Business 300 Series Switch
در کسب و کارهای امروزی سازمان ها و ادارات کوچکی وجود دارند که نیازمند به پروتکل ها و تکنولوژی های جدید در قسمت سوییچینگ خود هستند ولی به دلیل کوچکی سازمان تهیه سوئیچ های پیشرفته،از نظر مالی برای آن ها مرقون به صرفه نیست. شرکت سیسکو با ارائه سوئیچ های سری 300 که در دسته Small Business ها قرار دارند این نوید را به این سازمان ها داده است که با تهیه این سوئیچ ها می توانند به برخی از پروتکل ها و تکنولوژی های سوئیچ های لایه distribution و core دسترسی داشته باشند.
سوئیچ های سری 300 سیسکو با قیمت های بسیار مناسب وارد بازار شده اند که این سوئیچ ها در مدل های 8 پورت تا 48 پورت با سرعت 100/10 و 10 پورت تا 52 پورت با سرعت 1000/100/10 برای شبکه سازمان های کوچک طراحی شده اند و ما میتوانیم با کمک آن، کامپیوترها ، اکسس پوینت ها ، پرینترها و سرورها را در شبکه سازمان به یکدیگر اتصال دهیم و همچنین این سوئیچ ها دارای آپلینک های combo mini-Gbic (فیبر نوری) بر روی خود هستند.
سوئیچ های سری 300 سیسکو در سازمان های کوچک برای داشتن شبکه ای با قابلیت اطمینان بالا وداشتن بهترین عملکرد در ارائه سرویس های صدا، ویدئو، ارسال و دریافت داده ها کمک به سزایی کرده اند.
برخی از مدل های سوییچ های سری 300 از قابلیت PoE وPOE+ پیروی می کنند، که ما میتوانیم برای تامین انرژی مصرفی تلفن های ip و دوربین های مداربسته ip از آن ها استفاده کنیم.
از ویژگی های بارز این ســـــــوییچ سیسکو می توان به پشــتیبانی از IPv6، vlan، layer 3 static routing، ACL، SNMP V3، 802.1X (port security)، BPDU Guard، SSH، SSL، STP،RSTP ، MSTP،TFTP ، QOS و همچنین قابلیت آپدیت به نسل های آینده iosهای سیسکو و دارا بودن مکانیزیم های پیشرفته برای جلوگیری از ATTACK های همچون dhcp snooping و…… نام برد.
در پایان به مقایسه 4 محصول پرفروش و پر طرفدار از سری 300 سوئیچ های شرکت سیسکو میپردازیم:
