16 + 10 Tswj Gigabit Fiber Hloov
JHA-S1016MG-26 BC
♦Product Overview:
v Management Gigabit Fiber Hloov yog thib ob, plaub txheej gigabit tswj kev hloov, muab 10 10/100/1000M RJ45 ports thiab 16 1000M SFP optical ports. Lub hardware txhawb xaim-ceev hloov ntawm txheej thib ob. Cov neeg siv tuaj yeem teeb tsa txhua yam haujlwm ntawm kev hloov pauv los ntawm Ethernet chaw nres nkoj hauv WEB. Built-in ARP thiab DOS tiv thaiv kab ke tuaj yeem tiv thaiv ARP, DOS thiab ntau yam kab mob tawm tsam, ntxiv rau, Nws kuj tau nruab nrog ntau yam muaj zog: QoS dav dav, spanning ntoo, cua daj cua dub, Bandwidth Control, IGMP Snooping, ACL nkag. tswj, DHCP snooping thiab lwm yam..Zoo heev rau cov lag luam me thiab nruab nrab, lub tsev kawm ntawv network, thiab thaj chaw hauv nroog network kev sib sau ua ke.
♦Khoom nta:
- ARP tiv thaiv: kev ua haujlwm ntawm MAC chaw nyob thiab chaw nres nkoj khi thiab MAC chaw nyob ruaj ntseg lim tuaj yeem tiv thaiv ARP nres; DHCP snooping tuaj yeem muab kev tiv thaiv ARP rau cov neeg siv kom tau txais MAC dynamically.
- Qos: txhawb rau ntau lub tswv yim QOS. Raws li 802.1p qhov tseem ceeb, txhua qhov chaw nres nkoj muab yim qhov tseem ceeb. IP-DSCP tuaj yeem muab faib ua ntau theem kev pabcuam raws li IP header, kom ua tiav QOS. AUTO VOIP tuaj yeem teeb tsa qhov chaw nres nkoj rau qhov tseem ceeb tshaj plaws ntawm lub suab teeb liab, txhim kho lub suab zoo ntawm network IP xov tooj zoo heev.
- Spanning Tree: Txhawb nqa tus qauv ntawm IEEE 802.1d thiab IEEE 802.1w (Rapid Spanning Tree Protocol) thiab IEEE 802.1s (Multiple Spanning Tree Protocol).
- AUTO DOS: tiv thaiv cov nram qab no DOS nres nrog xya daim ntawv sib txawv.
(1) Kev tawm tsam hauv av: tus neeg tawm tsam xa cov ntaub ntawv sib tw TCP SYN cov ntaub ntawv ntws nrog tib qhov chaw IP chaw nyob, IP chaw nyob, tus neeg raug tsim txom lawv sim xa cov ntaub ntawv teb rau nws tus kheej, ua rau muaj kev cuam tshuam hauv lub cev thiab yuav ua rau tuag tes tuag taw lossis rov pib dua. .
(2) Blat nres: tus neeg tawm tsam xa cov pob ntawv forged nrog tib qhov chaw nres nkoj tus lej thiab tus lej chaw nres nkoj, cov neeg raug tsim txom sim xa cov lus teb rau nws tus kheej, ua rau lub cev poob lossis rov pib dua.
(3) Smurf nres: tus neeg tawm tsam siv qhov chaw nyob tsis zoo ntawm lub hom phiaj kev tawm tsam los khiav cov txheej txheem ping mus rau qhov chaw tshaj tawm. Tom qab ntawd tag nrho cov neeg ua haujlwm nquag yuav teb rau lub hom phiaj, ua rau muaj kev sib tsoo lossis kev cuam tshuam.
(4) Ping dej nyab: dej nyab lub hom phiaj los ntawm ping tshaj tawm cua daj cua dub, kom lub kaw lus tsis tuaj yeem teb rau cov ntaub ntawv raug cai.
(5) SYN / SYN-ACK dej nyab: dej nyab lub qhov phiaj xwm los ntawm SYN lossis SYN / ACK pob ntawv.
(6) Tiv thaiv qhov tsis raug TCP nres: Tiv thaiv dej nyab ntawm cov ntaub ntawv los ntawm cov pob ntawv TCP tsis raug.
(7) Ping of Death attack: xa tawm ib daim ntawv thov ICMP loj heev ("Ping"), nws lub hom phiaj yog ua kom lub hom phiaj ntawm lub khoos phis tawj tso tawm tsis txaus, kom lub khoos phis tawj tuag tes tuag taw.
5. Kev tiv thaiv cua daj cua dub: tuaj yeem teeb tsa nrog Broadcast, multicast, DLF tsheb.
6. ACL Access Control: siv los tswj kev sib pauv ntawm cov pob ntawv los ntawm qhov chaw nres nkoj, kom ntseeg tau tias qhov chaw intranet yuav tsis nkag mus rau cov neeg siv yam tsis muaj cai, thaum tiv thaiv ARP tsis ncaj ncees.
7. IGMP Snooping: Kev them nyiaj yug IGMP version 2 (RFC 2236): IGMP Snooping yog siv los tsim cov pab pawg multicast kom xa cov pob ntawv ntau ntau kom tsis txhob nkim bandwidth thaum lub pob ntawv multicast overflow network.
8. Kev them nyiaj yug rau 802.1x authentication, thiab muab cov neeg siv nkag mus rau kev lees paub.
9. Hlau-ceev filtering – Cia – rau pem hauv ntej hom, muab ib tug tseeb tsis-blocking switching qauv.
10. Txhawb kev ua haujlwm ntawm chaw nres nkoj mirroring, chaw nres nkoj sib sau ua ke, chaw nres nkoj ceev txwv.
11. Txhawb qhov chaw nres nkoj raws VLAN thiab IEEE802.1Q raws li VLAN .
