SPAN
Urashobora gukoresha imikorere ya SPAN kugirango wandukure paki kuva ku cyambu cyagenwe ujya ku kindi cyambu kuri switch ihujwe nigikoresho cyo kugenzura imiyoboro yo gukurikirana imiyoboro no gukemura ibibazo.
SPAN ntabwo ihindura paki yo guhana hagati yicyambu cyaturutse nicyambu. Ibipaki byose byinjira nibisohoka biva ku cyambu biva mu cyerekezo. Ariko, niba ibinyabiziga byindorerwamo birenze umurongo wicyerekezo cyicyerekezo, kurugero, niba icyambu cya 100Mbps gikurikirana urujya n'uruza rwicyambu cya 1000Mbps, paki zirashobora gutabwa.
RSPAN
Indorerwamo ya kure (RSPAN) niyagurwa ryicyerekezo cyaho (SPAN). Indorerwamo ya kure yerekana kure ibyambu byerekana ko icyambu cyaturutse hamwe nicyambu kigomba kuba kiri ku gikoresho kimwe, bigatuma icyambu cyaturutse hamwe nicyambu kigana ibikoresho byinshi byurusobe. Muri ubu buryo, umuyobozi wurusobe arashobora kwicara mucyumba cyibikoresho bikuru hanyuma akareba paki zamakuru zicyambu cya kure cyerekanwa binyuze mubisesengura.
RSPANyohereza paki zose zindorerwamo kumurongo wicyerekezo cyibikoresho byerekana indorerwamo ya kure binyuze muri RSPAN VLAN idasanzwe (yitwa Remote VLAN) Inshingano yibikoresho biri mubyiciro bitatu:
1.
2) Guhindura Hagati: murusobe hagati yinkomoko n’aho ujya, uhindure, indorerwamo unyuze muri packet ya kure ya VLAN ijya kurindi cyangwa guhinduranya hagati. Niba inkomoko ihindagurika ihujwe neza nu cyerekezo cyerekezo, nta guhinduranya hagati ibaho.
3) Icyerekezo Guhindura: Icyerekezo cya kure cyerekezo cyerekezo cya switch, indorerwamo kuva kure ya VLAN kugirango wakire ubutumwa unyuze kumurongo wicyerekezo werekeza kugenzura ibikoresho.
ERSPAN
Encapsulated Remote port mirroring (ERSPAN) niyagurwa ryerekana indorerwamo ya kure (RSPAN). Mubisanzwe byicyerekezo cyicyerekezo cyicyerekezo, paki yindorerwamo irashobora koherezwa kumurongo wa 2 gusa kandi ntishobora kunyura mumurongo wanyuze. Mugihe gikubiyemo icyambu cya kure cyerekana indorerwamo, paki yindorerwamo irashobora koherezwa hagati yimiyoboro iyobowe.
ERSPAN ikubiyemo paki zose zindorerwamo mumapaki ya IP ikoresheje umuyoboro wa GRE ikanayerekeza ku cyerekezo cyerekezo cyibikoresho bya kure byerekana. Inshingano za buri gikoresho zigabanijwemo ibyiciro bibiri:
1.
2.
Kugirango ushyire mubikorwa ibikorwa bya kure byerekana indorerwamo, ipaki ya IP igizwe na GRE igomba kuba igendanwa kubikoresho byerekanwe kumurongo.
Ipaki Encapsulation isohoka
Gushyigikirwa kugirango ushiremo udupaki twose twerekanwe mumodoka yafashwe kumutwe wa RSPAN cyangwa ERSPAN hanyuma usohokane paki kuri sisitemu yo kugenzura inyuma cyangwa guhinduranya imiyoboro
Umuyoboro wuzuye
Gushyigikira ibikorwa bya tunnel paketi yo kurangiza, ishobora kugena aderesi ya IP, masike, ibisubizo bya ARP, hamwe nibisubizo bya ICMP kubicuruzwa byinjira mumodoka. Imodoka igomba gukusanywa kumurongo wabakoresha yoherejwe mubikoresho binyuze muburyo bwa tunnel uburyo bwa GRE, GTP, na VXLAN
VxLAN, VLAN, GRE, Umutwe wa MPLS
Bishyigikiye VxLAN, VLAN, GRE, MPLS umutwe wambuwe mumapaki yumwimerere hanyuma wohereze ibisohoka.
