v JHA-S2024MG-26BC Series Gigabit Managed Fiber Switches bụ nke abụọ, oyi akwa nke anọ gigabit jisiri mgba ọkụ. Ngwa ngwaike na-akwado ngbanwe ọsọ waya nke oyi akwa nke abụọ. Ndị ọrụ nwere ike ịtọ ụdị ọrụ ọ bụla nke mgba ọkụ site na ọdụ ụgbọ mmiri Ethernet dị na WEB. Sistemụ nchekwa ARP na DOS wuru nwere ike gbachitere ARP, DOS na ọgụ nje dị iche iche. Ọzọkwa JHA-S2024MG-26BC Series Switches nwekwara onwem na ọtụtụ ike atụmatụ: a keukwu QoS, spanning osisi, a oké ifufe suppression, Bandwit Control, IGMP Snooping, ACL ohere akara, DHCP snooping wdg Dị nnọọ adabara obere na ọkara-sized ụlọ ọrụ, netwọk campus, na ngwa nchịkọta netwọk mpaghara mepere emepe.

Nchekwa ARP: ọrụ nke adreesị MAC na njikọ ọdụ ụgbọ mmiri na nzacha adreesị MAC nwere ike chebe ọgụ ARP nke ọma; DHCP snooping nwere ike inye nchebe ARP maka ndị ọrụ iji nweta MAC ike.

2. Qos: nkwado maka otutu QOS atụmatụ. Dabere na ntọala izizi 802.1p, ọdụ ụgbọ mmiri ọ bụla na-enye ahịrị asatọ dị mkpa. Enwere ike kewaa IP-DSCP gaa na ọkwa ọrụ dị iche iche dịka isi okwu IP siri dị, iji nweta QOS zuru oke.
