Span
Iwe unogona kushandisa span basa kuti utore mapaketi kubva kune yakataurwa chiteshi kune chimwe chiteshi icho chakabatanidzwa kune network yekutarisa network yekuongorora network uye kugadzirisa dambudziko.
Span haina kukanganisa packet yekutsinhana pakati pechiteshi chekodhi uye chivakwa chekuenda. Makapu ese anopinda uye kubuda kubva kune chiteshi chekodhi anoteedzerwa kuChienda Chiteshi. Nekudaro, kana iyo manhamba akaomeswa inodarika bandwidth yechiteshi chenzvimbo, semuenzaniso, kana iyo 100mbps yekuenda kuPort monitors iyo traffic ye 1000mbps sosi yechikepe, mapaketi anogona kuraswa
RSPAN
Remote Port Carration Remote portunganidza kurambidza kurambidzwa kuti iyo Source Port uye Constiteshi inofanirwa kunge iri pane imwecheteyo mudziyo, ichigonesa chiteshi chekodhi kune mapfumo mitezo yemhando yemitezo. Nenzira iyi, iyo maneja maneja anogona kugara mumakamuri epakati emidziyo uye tarisa mapaketi edata eyekure kweiyo iri kure chiteshi kuburikidza neAuguration.
RSPANInotumira midziyo yese yakarongedzwa pachiteshi chekuenda kwechiteshi chegirazi kuburikidza neicho chakakosha RSRA (inonzi iri kure vlan) matanho emidziyo inowira mumapoka matatu:
1) Source switch: Remote mufananidzo sosi chiteshi cheSwitch
2) Intermediate Switch: In network pakati peiyo sosi uye Switch Switch, switch, girazi kuburikidza nelnote vlan packet kuendesa kune inotevera kana kuchinjisa pakati. Kana iyo Source switch yakabatana zvakananga kune iyo yekuenda switch, hapana iyo yepakati switch iripo.
3) Kuenda Switch: Remote Girration Kuenda Port yeSwitch, Girazi kubva kure VLAN kugashira meseji kuburikidza negirazi kuenda kuComment Port kuendesa kune Monitor
Erspan
Yakagadziriswa kure kure porting Mune imwe nzvimbo iri kure porting Mune yakagadziriswa kure kure porting chikamu chimwe chikamu, makapu yakarongedzwa inogona kutapurirwa pakati pemasokisi akaomeswa.
Erspan encapsulates ese macacked mapaketi mune IP mapaketi kuburikidza neGre tunnel uye anoiendesa kune iyo yekuenda kuchiteshi chegirazi remhepo rekufamba. Misoro yechinhu chimwe nechimwe chakakamurwa kuita mapoka maviri:
1) Source switch: Encapasulation Remote Image Source Port of Switch, kuburikidza neGre switch Switch Buttencudes, kubudikidza neGre yakaiswa muPacket yekuendesa, kuendesa zvinoputira kune chinangwa.
2) Kuenda Switch.
Kuita kuti ishandiswe yeporini yegirazi, ip mapepa engariti inofanirwa kunge ichikwanirisa kune iyo nzvimbo yekuenda kune imwe drive mudziyo pane network
Packet encapsulation kubuda
Inotsigirwa kuti ishanduke chero yakatarwa mapaketi mune yakabatwa traffic kune RSPAN kana Erspan Header uye inoburitsa mapaketi ekudzokera kumashure
Tunnel packet kubviswa
Kutsigira iyo tunnel packet yekubviswa basa rekutumbuka, iyo inogona kugadzirisa kero dzeIP, masks, ARP mhinduro, uye mhinduro mhinduro dzePraffic Int traffiti. Traffic kuti iunganidzwe pane mushandisi network inotumirwa zvakananga kune iyo mudziyo kuburikidza neTunnel encapsation nzira dzakadai se gre, gtp, uye vxlan
Vxlan, vlan, gre, MPLS Header stripping
Inotsigira vxlan, vlan, gre, mpls musoro wakabvarurwa muiyo yekutanga data packet uye inotumirwa kuendesa kunze.
