Mokhoa oa ho khetholla le ho khetha li-switches?
Li-switches li sebelisoa haholo mererong e fokolang ea marang-rang ea hona joale, 'me mefuta eohle ea phetisetso ea data ha e arohane le bona. KajenoJHA Teche tla bua ka lintlha tsa ho khetholla le ho khetha li-switches.
- Khethollo ea li-switches
- 1-1 Ho latela sebopeho sa marang-rang: e arotsoe ka li-switches tsa lera la phihlello, li-switches tsa lera la aggregation le li-switches tsa mantlha.
1-2 Ho ea ka mohlala oa OSI: e arotsoe ka li-switch tsa 2, li-switch tsa 3, li-switch tsa 4, joalo-joalo, ho ea ho li-switch tse 7.
1-3 Tsamaiso ea li-switches: Phapang pakeng tsa li-switches tse laoloang le li-switches tse sa laoloang li itšetlehile ka tšehetso ea bona bakeng sa li-protocol tsa tsamaiso ea marang-rang tse kang SNMP le RMON.
JHA Tech, ke moetsi oa mantlha o inehetseng ho R&D, tlhahiso, le thekiso ea Ethernet Switches, Media Converter, PoE Switch & Injector le module ea SFP le lihlahisoa tse ngata tse amanang le lilemo tse 17. Ts'ehetsa OEM, ODM, SKD joalo-joalo.
Hape e be le phepelo e felletseng ea sehlahisoa, sehlopha se matla sa R&D, mochini o arabelang kapele ka mor'a thekiso, le boiphihlelo bo holileng ba kopo ea tharollo.
JHA Tech e na le sehlopha sa botekgeniki sa batho ba fetang 20 ba nang le boiphihlelo bo tloaelehileng ba ho sebetsa ba lilemo tse fetang 15, mme ba ka rarolla bothata ba hau nakong ea metsotso e 30 kapele.
2.Main reference lintlha bakeng sa khetho ea switjha
a.Backplane bandwidth, Layer 2/3 switching throughput.
b.VLAN mofuta le nomoro.
c.Palo le mofuta oa likou tsa switjha.
d.Tsehetsa liprothokholo tsa tsamaiso ea marang-rang le mekhoa. Li-switches lia hlokahala ho fana ka taolo e bonolo le e bohareng.
e, Qos, 802.1q taolo ea pele, 802.1X, tšehetso ea 802.3X.
f.Stacking tšehetso.
g.Switch switching cache, port cache, main memory, tieho ea ho fetisa le liparamente tse ling.
h.Molao oa ho fetisa lebelo, boholo ba tafole ea ho tsamaisa, boholo ba lenane la taolo ea phihlello, ts'ehetso ea li-protocol tsa routing, ts'ehetso ea li-protocol tsa multicast, mekhoa ea ho sefa lipakete, bokhoni ba ho atolosa mochine, joalo-joalo ke litekanyetso tsohle tse lokelang ho nahanoa 'me li lokela ho batlisisoa ho latela maemo a sebele.
Haeba o hloka tharollo ea ho khetha switch, ka kopo siea aterese ea hau ea lengolo-tsoibila mme re tla ba le setsebi sa ho ikopanya le uena bakeng sa likarabo tsa motho ka mong.
