S5456XC bụ oyi akwa-3 mgba ọkụ nwere 48 x 25GE(SFP+) na 8 x 100GE(QSFP28).Ọ bụ ngbanwe ohere ọgụgụ isi nke ọgbọ na-abịa maka netwọkụ ndị na-ebu ibu na netwọkụ ụlọ ọrụ.Ọrụ ngwanrọ nke ngwaahịa a bara ụba nke ukwuu, nkwado ntụgharị IPv4 / IPv6, ikike mgbanwe, nkwado siri ike na kwụsie ike RIP/OSPF/RIPng/OSPFv3/PIM protocols routing protocol, yana atụmatụ ndị ọzọ.The ebugharị bandwit na ibuga ikike dị ukwuu, na-egbo mkpa nke data centers na isi netwọk na netwọọdụ azụ.
Q1: Ị nwere ike ịgwa m gbasara oge ịkwụ ụgwọ gị?
A: N'ihi na samples, 100% ugwo n'ihu.N'ihi na nnukwu iji, T / T, 30% tupu ugwo, 70% itule tupu Mbupu.
Q2: Kedu ka oge nnyefe gị dị?
A: 30-45days, ọ bụrụ na nhazi gị dị ukwuu, ọ ga-ewe obere oge.
Q3: ONTs/OLT gị nwere ike dakọtara na ngwaahịa ndị ọzọ?
A: Ee, ONTs/OLT anyị dakọtara na ngwaahịa ndị ọzọ n'okpuru ọkọlọtọ ọkọlọtọ.
Q4: Ogologo oge ole ka oge ikike gị dị?
A: 1 afọ.
Q5: Kedu ihe dị iche n'etiti EPON GPON OLT na XGSPON OLT?
Nnukwu ihe dị iche bụ na XGSPON OLT na-akwado GPON/XGPON/XGSPON, Ọsọ Ọsọ.
Q6: Gịnị bụ ụzọ ịkwụ ụgwọ anabatara maka ụlọ ọrụ gị?
Maka sample, 100% ugwo n'ihu.N'ihi na ogbe iji, T / T, 30% nkwụnye ego, 70% itule tupu nnyefe.
Q7: Ụlọ ọrụ gị ọ nwere akara nke ya?
Ee, akara ụlọ ọrụ anyị bụ Lime.A Layer 3 mgba ọkụ bụ ụdị mgbanwe netwọk na-arụ ọrụ na netwọk netwọk nke ụdị OSI.Nke a pụtara na ọ nwere ikike ịme mkpebi ntụgharị dabere na adreesị IP, dị ka rawụta.A na-ejikarị ọkụ ọkụ Layer 3 eme ihe na netwọk ụlọ ọrụ iji jikọọ subnet dị iche iche wee mee mkpebi gbasara ebe a ga-ebuga okporo ụzọ.
Yabụ, kedu ihe bụ ngbanwe Layer 3 na kedu ka o si dị iche na mgba ọkụ Layer 2 omenala?Ngbanwe Layer 2 na-arụ ọrụ na oyi akwa njikọ data nke ụdị OSI ma na-eme mkpebi mbugharị dabere na adreesị MAC.Ọ bụ ezie na ọ na-arụ ọrụ nke ọma n'ịkwagharị okporo ụzọ n'ime otu subnet, ọ nweghị ikike ịme mkpebi ntụgharị maka okporo ụzọ na-aga na subnet dị iche iche.Nke a bụ ebe mgba ọkụ Layer 3 na-abata.
Mgbanwe nke Layer 3 na-ejikọta ọrụ nke mgba ọkụ oyi akwa 2 omenala yana ike ịkwọgharị nke rawụta.Ọ nwere ike ịmepụta mebere LANs (VLAN) na ụzọ okporo ụzọ n'etiti ha, yana ịme mkpebi gbasara ụzọ kacha mma maka okporo ụzọ isi na netwọk.Nke a na-eme ka ọ bụrụ ngwá ọrụ dị ike maka ijikwa na ịkwalite okporo ụzọ netwọk na nnukwu netwọk dị mgbagwoju anya.
Otu n'ime uru dị mkpa nke iji mgba ọkụ Layer 3 bụ ikike ya iji melite arụmọrụ netwọk.Site n'iwepụ ụfọdụ ọrụ ntụgharị site na isi rawụta gaa na mgba ọkụ Layer 3, enwere ike kesaa okporo ụzọ netwọkụ nke ọma, na-eduga na nkwurịta okwu ngwa ngwa na ntụkwasị obi n'etiti ngwaọrụ na netwọkụ.
N'ozuzu, mgba ọkụ Layer 3 bụ ihe bara uru maka ụlọ ọrụ nwere mkpa netwọk dị mgbagwoju anya.Ikike ya ijikọta ọrụ nke mgba ọkụ na onye rawụta na-eme ka ọ bụrụ ihe dị mkpa maka ijikwa na ịkwalite okporo ụzọ netwọkụ.Ka azụmahịa na-aga n'ihu na-adabere na ngwọta netwọk siri ike ma dị irè, Layer 3 switches ga-aga n'ihu na-arụ ọrụ dị oke mkpa n'ịhụ na data na-aga n'enweghị nsogbu na ntụkwasị obi na netwọk niile.
