Isithombe esithi
Ungasebenzisa umsebenzi we-span ukukopisha amaphakethe kusuka ethekwini elicacisiwe kwelinye itheku ku-switch exhunywe kwidivaysi yokuhlola inethiwekhi nokuxazulula inkinga.
I-SPAN ayithinti ukushintshaniswa kwephakethe phakathi kwechweba lomthombo kanye nechweba lapho uya khona. Wonke amaphakethe angena futhi akhipha kusuka echwebeni lomthombo akopishwa ethekwini lapho uya khona. Kodwa-ke, uma ithrafikhi ebonile idlula i-bandwidth yokuya ethekwini lapho uya khona, ngokwesibonelo, uma i-100mbps Port port iqapha ithrafikhi ye-1000MBPS Soucce Port, amaphakethe angalahlwa
I-RSPAN
I-Remote Port Port (RSPAN) isandiso se-portroring yendawo (SPAN). I-portroring eyihlane yephula umkhawulo wokuthi i-Port Port ne-Destination Port kumele ibe kudivayisi efanayo, inika amandla i-Source Port kanye nePorty Port kumadivayisi wenethiwekhi amaningi. Ngale ndlela, umphathi wenethiwekhi angahlala egumbini lemishini eliphakathi futhi abheke amaphakethe wedatha echwebeni elikude elibunjiwe nge-analyzer.
I-RSPANIdlulisela wonke amaphakethe abunjiwe ethekwini lapho uya khona kwidivaysi eyihlane yesibuko nge-RSPAN VLAN ekhethekile (ebizwa ngokuthi i-Vlan Remote) Izindima zamadivayisi ziwela ezigabeni ezintathu:
1) Shintsha Umthombo: I-Remote Image Source Port of switch, inesibopho sekhophi yomlayezo wetheku lomthombo ophuma endaweni yokuphuma komthombo okhipha, ngokudlulisela okukude kwe-VLAN, shintsha.
2) I-Intermediate Shintle: Kunethiwekhi phakathi komthombo nokushintshwa kwendawo, switch, isibuko ngokudluliswa kwe-Vlan Packet okulandelayo noma ukushintsha phakathi. Uma inkinobho yomthombo ixhumeke ngqo ekushintsheni lapho uya khona, akukho shintsho oluphakathi nendawo olukhona.
3) Ukushintshwa kwe-Destination Port: I-Remor Remor Destination Port of switch, isibuko kusuka ku-vlan eyihlane ukuthola umyalezo ngokudluliswa kwe-Mirror Destination Port ukubheka imishini.
I-Erspan
I-EnterPlated Port portroring Remorer Port (Erspan) isandiso se-Remote Port Port (RSPAN). Esimweni esikude esikude sephakethe leseshini, amaphakethe abunjiwe angadluliselwa kuphela ku-under 2 futhi awakwazi ukudlula kwinethiwekhi ehambisanayo. Esimweni esibukweni esikude seseshini esinqunyelwe, amaphakethe abunjiwe angadluliswa phakathi kwamanethiwekhi ahambisanayo.
I-Erspan ihlanganisa wonke amaphakethe abunjiwe emaphaketheni we-IP ngomhubhe we-GRE futhi awahambisa ethekwini lapho uya khona kwidivayisi yesibuko esikude. Izindima zedivayisi ngayinye zihlukaniswe izigaba ezimbili:
1) Shintsha umthombo
2) Ukushintshwa kwe-Destination Port: I-Encopsort Remor Revestise Port of switch, izothola umyalezo ngokusebenzisa isibuko se-Mirror Mirrorport, ngemuva kokudluliselwa komyalezo we-GRE ukuqapha imishini.
Ukusebenzisa umsebenzi wokubukisa obala okukude, amaphakethe we-IP ancono nge-GRE kumele akwazi ukuya kudivayisi yesibuko sokufika kwinethiwekhi
Ukukhishwa kwePacket Encopsetion
Ixhaswe ukunxenxa noma yimaphi amaphakethe acacisiwe kuthrafikhi efakiwe kwi-RSPAN noma i-Erspan Header futhi akhiphe amaphakethe ohlelweni lokuqapha emuva kwe-wack-end noma switch
Ukupheliswa kwephakethe
Uxhasa umsebenzi wokuqedwa kwephakethe lomhubhe, ongamisa amakheli e-IP, imaski, izimpendulo ze-arp, nezimpendulo ze-ICMP zamachweba wokufaka ithrafikhi. Ithrafikhi ezoqoqwa kwinethiwekhi yomsebenzisi ithunyelwa ngqo kudivayisi ngezindlela ze-tunnel acphungulation ezifana ne-GRE, i-GTP, ne-Vxlan
Vxlan, Vlan, GRE, MPLS Header Strip
Ixhase i-Vxlan, i-VLAN, GRE, unhlokweni we-MPL osuswe ephaketheni ledatha yasekuqaleni futhi athumele okuthunyelwe.
