12 + 8 + 1 10Gigabit Fiber Itarangi Whakawhiti
JHA-SWG812MG-20BC
Tirohanga Hua
12 + 8 + 1 10Gigabit Data Center Whakawhiti he paparanga 2 kore-aukati whakawhiti me te maramara Broadcom. Te whakarato 258Gbps kaha whakawhiti me te 192Mpps mahi whakamua, L2 / L3 waea-tere whakamua tonu. Ko tana kaha o te whatunga ngawari e whakarite ana i te pumau o te whatunga me te toenga o te hononga kawenga. Ma te hoahoa modular, e whakarato ana i te 12 10G SFP + tauranga whatu, 8 10/100/1000M RJ45 tauranga hiko, 1 tauranga Console, 1 tauranga whakahaere OOB, e tuku nui ana te bandwidth mo te whakahiato raraunga me te whakawhiti raraunga. A, kia pai ai te whakautu ki nga whakaritenga whatunga, ka taea e nga kaiwhakamahi te kowhiri i nga tauranga 10G e tika ana kia rite ki o raatau hiahia.Ki te nui o te bandwidth me te iti o te waahi, te whatunga paipa., JHA-SWG812MG-20BC kei roto i te kiato o te reanga o muri o te pokapū raraunga me te kapua. te uru ki te whatunga rorohiko, ka taea hoki te whakamahi mo nga kawhe Ipurangi nui, te matua o te whatunga hinonga, te whatunga rohe taone nui, te whakahiato ranei.
Āhuahira Hua

3. Whakawhāitihia te maha o nga kaihautu e hono ana ki te tauranga, te atanga Itarangi-maha, te whakanui ake i te bandwidth me te kore o te punaha;
4. ACL kaha, tautoko L2-L4 tātari raraunga;
5. Te rarangi whakahaere kaupapa here me te ture rere.
He watea ki te mahi me te tiaki
1. Tautoko whirihoranga tauranga hangore;
2. Tautoko whakahaere me te Tukutuku, SNMP me te telnet;
3.Tautoko te kawa XModem, whakamahia te TFTP/ZMODEM ki te whakahou rorohiko me te whakahou BootRom;
4.Tautoko SFP +, hoki whakamuri hototahi XFP;
5. Whakauruhia, puta atu ranei te ahua iti-hiko mai i te PHY.
Te Rere Kaha me te Whakahaere Paoho
1. Ka kitea aunoa me te whakahaere i te tupuhi haapurororaa, tautoko i nga paatete IGMP, ka whakawhāiti i te waipuke o nga paanui panui;
2. Tautokohia te atanga Itarangi kia 1M te roa o te taahiraa mo te whakaiti reiti.
3. Tautokohia te aratau taarua katoa me te mana rere aratau haurua;
4. Tautoko IP multicast me QoS.
