16 + 10 Whakahaere Gigabit Fiber Whakawhiti
JHA-S1016MG-26BC
♦Tirohanga hua:
v Ko te Whakahaere Gigabit Fiber Switch te tuarua, te wha o nga paparanga gigabit kua whakahaeretia, e whakarato ana i nga tauranga 10 10/100/1000M RJ45 me nga tauranga whatu 16 1000M SFP. Ka tautokohia e te taputapu pakeke te whakawhiti waea-tere o te paparanga tuarua. Ka taea e nga kaiwhakamahi te whakarite i nga momo mahi katoa o te whakawhiti ma te tauranga Ethernet i roto i te WEB. Ka taea e te punaha tiaki ARP me te DOS te tiaki i te ARP, DOS me nga momo whakaeke huaketo, hei taapiri, he maha nga waahanga kaha: he QoS matawhānui, he rakau whanui, he aukati tupuhi, Mana Aratuku, IGMP Snooping, ACL uru. mana, DHCP snooping etc..He tino pai mo nga hinonga iti me te reo-rahi, whatunga puni, me nga tono whakahiato whatunga rohe metropolitan.
♦āhuatanga hua:
- ARP parepare: te mahi o te wāhitau MAC me te tauranga herea me te tātari haumaru wāhitau MAC taea tōtika te tiaki i te whakaeke ARP; Ka taea e DHCP snooping te whakarato i te whakamarumaru ARP mo nga kaiwhakamahi ki te tiki i te MAC hihiri.
- Qos: tautoko mo te rautaki QOS maha. I runga i te whakatakotoranga kaupapa matua 802.1p, ka whakawhiwhia e ia tauranga nga rarangi matua e waru. Ka taea te wehewehea IP-DSCP ki nga taumata ratonga rereke e ai ki te pane IP, ki te whakatutuki i te QOS matawhānui. Ka taea e AUTO VOIP te whakanoho i te tauranga ki te kaupapa matua o te tohu reo, te whakapai ake i te kounga reo o te waea IP whatunga.
- Rakau Whakawhiti: Tautokohia te paerewa o IEEE 802.1d me IEEE 802.1w (Rapid Spanning Tree Protocol) me IEEE 802.1s (Multiple Spanning Tree Protocol).
- AUTO DOS: arai i te whakaeke DOS e whai ake nei me nga momo rereke e whitu.
(1) Ko te whakaeke whenua: ka tukuna e te kaitukino nga paakete TCP SYN o te rere korero me te wahitau IP puna kotahi, te wahitau ūnga IP , ka ngana te punaha patunga ki te tuku korero whakautu ki a ia ano, ka puta he raruraru o te punaha, ka pararutiki, ka timata ano. .
(2)Ko te whakaekenga: ka tukuna e te kaitukino nga paakete tinihanga me te tau tauranga puna kotahi me te tau tauranga taunga, ka ngana te punaha patunga ki te tuku korero whakautu ki a ia ano, ka puta ka pakaru te punaha, ka whakaara ano ranei.
(3)Ko te whakaeke Smurf: ka whakamahia e te kaitukino te wahitau puna korero o te whaainga whakaeke hei whakahaere i te mahi ping ki tetahi wahitau haapurororaa. Na ka whakautu nga kaihautu hohe katoa ki te whaainga, ka pa mai ki te kupenga, ka pakaru ranei.
(4)Ping Waipuke: waipuke te pūnaha ūnga e te ping haapurororaa tupuhi, kia kore e taea e te pūnaha whakautu ki reta tika.
(5) SYN/SYN-ACK waipuke: waipuke te pūnaha ūnga poka e SYN ranei SYN / ACK pākete.
(6) Tiaki i te whakaeke TCP muhu: Aukati i te waipuke o nga raraunga na nga paatete TCP muhu.
(7) Ping of Death whakaeke: Ka tukuna he putea tono ICMP tino nui ("Ping"), ko tana hiahia kia puhake te papaa whakaurunga rorohiko, kia pararutiki te rorohiko.
5. Te aukati awha: ka taea te whakarite me te Whakawhitiwhiti, multicast, DLF hokohoko.
6. ACL Access Control: whakamahia ki te whakahaere i te whakawhitinga o te putea mai i te tauranga, ki te whakarite kia kore te pae ipurangiroto e uru ki nga kaiwhakamahi kore mana, me te tiaki autaki i te whakaeke ARP.
7. IGMP Snooping: Tautokohia te putanga IGMP 2 (RFC 2236): Ka whakamahia te IGMP Snooping ki te whakatu i nga roopu multicast ki te tuku i nga paatete maha kia kore ai e moumou te paanui i te wa e rere ana te kupenga e rere ana te paatete maha.
8. Tautoko mo te whakamotuhēhēnga 802.1x, me te whai wāhi ki ngā kaiwhakamahi ki te whakamotuhēhēnga.
9. Waea-tere tātari - Rokiroki - aratau whakamua, whakarato i te hanganga whakawhiti kore-aukati pono.
10. Tautokohia te mahi o te whakaata tauranga, te kohi tauranga, te rohe tere tauranga.
11. Tautokohia te VLAN me te IEEE802.1Q i runga i te VLAN.
