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.

1. 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. AUTO VOIP nwere ike ịtọ ọdụ ụgbọ mmiri ka ọ bụrụ ihe kacha mkpa maka mgbama olu, kwalite ogo olu ekwentị IP netwọkụ nke ukwuu.

3. Osisi na-agba agba: Kwado ụkpụrụ nke IEEE 802.1d na IEEE 802.1w (Protocol Tree Rapid Spanning) na IEEE 802.1s (Multiple Spanning Tree Protocol).

4. AUTO DOS: chebe ọgụ DOS ndị a na ụdị asaa dị iche iche.

(1) Mwakpo ala: onye na-awakpo ahụ na-eziga ngwugwu TCP SYN adịgboroja nke ozi na-aga n'otu adreesị IP, adreesị ebe adreesị IP, usoro ihe omume ahụ na-anwa iziga ozi nzaghachi n'onwe ya, na-ebute ọgba aghara usoro ma ọ ga-akpọnwụ ma ọ bụ malitegharịa. .

(2) Mwakpo Blat: onye na-awakpo ahụ na-eziga ngwugwu adịgboroja nwere otu nọmba ọdụ ụgbọ mmiri na nọmba ọdụ ụgbọ mmiri, usoro ihe omume ahụ na-anwa iziga ozi nzaghachi n'onwe ya, na-ebute usoro mkpọka ma ọ bụ malitegharịa.

(3) Mwakpo Smurf: onye na-awakpo ahụ na-eji adreesị isi mmalite nke mbuso agha iji rụọ ọrụ ping na adreesị mgbasa ozi. Mgbe ahụ, ndị ọrụ niile na-arụ ọrụ ga-azaghachi ebumnuche, na-eduga na mkpọkọ netwọkụ ma ọ bụ ọgba aghara.

(4) Ping idei mmiri: idei mmiri na-ezubere iche usoro site ping mgbasa ozi oké ifufe, nke mere na usoro enweghị ike ịzaghachi ziri ezi ozi.

(5) SYN/SYN-ACK idei mmiri rikpuru: idei mmiri na-eju sistemu ebumnuche oghere site na SYN ma ọ bụ SYN / ACK ngwugwu.

(6) Chebe mbuso agha TCP na-ezighi ezi: gbochie iju mmiri data nke ngwugwu TCP na-ezighi ezi kpatara.

(7) Ping of Death attack: Na-ezipụ nnukwu ngwugwu arịrịọ ICMP ("Ping"), ebumnuche ya bụ ime ka ihe ntinye kọmpụta nke ebum n'uche na-ejupụta, nke mere na kọmputa ahụ kpọnwụrụ akpọnwụ.

5. Mbelata oké ifufe: enwere ike ịtọ ya na Mgbasa ozi, multicast, okporo ụzọ DLF.

6. ACL Access Control: eji achịkwa mgbanwe nke ngwugwu si n'ọdụ ụgbọ mmiri, iji hụ na intranet saịtị agaghị enweta ndị ọrụ na-enweghị ikike, na-na-apụtaghị ìhè na-agbachitere ARP ọgụ.

7. IGMP Snooping: Nkwado ụdị IGMP 2 (RFC 2236): A na-eji IGMP Snooping guzobe otu multicast iji zipu ngwugwu multicast iji zere ịla n'iyi bandwidth mgbe ngwugwu multicast na-ejupụta netwọk.

8. Nkwado maka nyocha 802.1x, na inye ndị ọrụ ohere ịnweta nkwenye.

9. Waya-ọsọ nzacha - Nchekwa - n'ihu mode, na-enye ezi na-abụghị igbochi ịmafe Ọdịdị.

10.Support ọrụ nke mirroring ọdụ ụgbọ mmiri, ọdụ ụgbọ mmiri na-achịkọta, ọdụ ụgbọ mmiri ịgba ọsọ.

11. Kwado VLAN nke ọdụ ụgbọ mmiri na IEEE802.1Q dabere na VLAN.
