♦Nchịkọta ngwaahịa:
v Management Gigabit Fiber Switch bụ nke abụọ, nke anọ oyi akwa gigabit jisiri mgba ọkụ, na-enye 10 10/100/1000M RJ45 ọdụ ụgbọ mmiri na 16 1000M SFP ngwa anya ọdụ ụgbọ mmiri. Ngwa siri ike na-akwado mgbanwe 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 wuru na DOS nwere ike ịgbachitere ARP, DOS na ọgụ nje dị iche iche, Ọzọkwa, A na-ejikwa ọtụtụ atụmatụ dị ike: QoS zuru oke, osisi na-efe efe, mbelata oke mmiri, njikwa bandwit, IGMP Snooping, ohere ACL. njikwa, DHCP snooping etc..Nnọọ adabara obere na ọkara-sized ụlọ ọrụ, campus netwọk, na metropolitan ebe netwọk mkpokọta. ngwa.
♦Njirimara ngwaahịa:
- 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.
- Qos: nkwado maka ọtụtụ atụmatụ QOS. 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.
- Osisi na-agba agba: Kwado ọkọlọtọ nke IEEE 802.1d na IEEE 802.1w (Protocol Tree Rapid Spanning) na IEEE 802.1s (Multiple Spanning Tree Protocol).

(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. Kwado ọrụ nke mirroring ọdụ ụgbọ mmiri, nchịkọta ọdụ ụgbọ mmiri, oke ọsọ ọdụ ụgbọ mmiri.
11. Kwado VLAN nke ọdụ ụgbọ mmiri na IEEE802.1Q dabere na VLAN.
