Kujambula Kwa Paketi Yophatikizidwa
Mbiri Yakale Yojambula Paketi Yophatikizidwa
Gome ili limapereka zomasulidwa komanso zokhudzana ndi zomwe zafotokozedwa mugawoli. Izi zimapezekanso m'mabuku onse otsatizana ndi omwe adalowetsedwamo, pokhapokha atadziwika mwanjira ina.
Gulu 1: Mbiri Yakale Yojambula Paketi Yophatikizidwa
| Kumasula | Mbali | Zambiri Zake |
| Cisco IOS XE Dublin 17.12.1 |
Paketi Yophatikizidwa Jambulani |
Mbali ya Embedded Packet Capture imakulitsidwa kuti ithandizire kukula kwa buffer, kujambulidwa kosalekeza, ndi kusefa ma adilesi angapo a MAC mumodzi Wophatikizidwa. Packet Capture (EPC) gawo. |
Zambiri Zokhudza Kujambula Kwa Paketi Yophatikizidwa
Chiwonetsero cha Embedded Packet Capture chimathandizira kutsata ndi kuthetsa mapaketi. The Embedded Packet Capture pa controller imagwiritsidwa ntchito pothana ndi zovuta zingapo, monga, kutsimikizira ndi RADIUS, AP kujowina kapena kulumikizidwa, kutumiza kwa kasitomala, kulumikizidwa, ndi kuyendayenda, ndi zina zapadera monga ma multicast, mDNS, ambulera, kuyenda, ndi so on.This Mbali imalola oyang'anira maukonde kuti agwire mapaketi a data omwe akuyenda, kupita, komanso kuchokera ku chipangizo cha Cisco. Mukathetsa kujowina kwa AP kapena vuto lolowera kasitomala, ngati simungathe kuyimitsa nkhani ikangochitika, chidziwitso chofunikira chikhoza kutayika. Nthawi zambiri, buffer ya 100 MB sikokwanira kulanda deta. Kuphatikiza apo, mawonekedwe a Embedded Packet Capture omwe alipo amathandizira kusefa kwa adilesi imodzi yamkati ya MAC, yomwe imagwira anthu ambiri kasitomala. Nthawi zina, zimakhala zovuta kutsimikizira kuti kasitomala opanda zingwe akukumana ndi vuto.
Kuchokera ku Cisco IOS XE Dublin 17.12.1, gawo la Embedded Packet Capture limathandizira kukula kwa buffer, kujambulidwa kosalekeza, ndi kusefa maadiresi angapo a MAC mu gawo limodzi lophatikizidwa la Packet Capture. Palibe masitepe a GUI kuti mukhazikitse kukulitsa kwa Embedded Packet Capture.
Kukonzekera Kujambula Paketi Yophatikizidwa (CLI)
Ndi Embedded Packet Capture feature, kukula kwa bafa kumawonjezeka kuchoka pa 100 MB kufika ku 500 MB.
Zindikirani
Buffer ndi yamtundu wa kukumbukira. Mutha kusunga chosungira kukumbukira kapena kukopera kukumbukira komwe kuli mu a file kusunga zambiri.

| Gawo 1 | ExampLe: athe Chipangizo> yambitsani |
Imathandizira mawonekedwe amtundu wa EXEC. Lowetsani mawu achinsinsi anu, ngati mukufunsidwa. |
| Gawo 2 | kuyang'anira kujambula epc-session-name mawonekedwe GigabitEthernet mawonekedwe-nambala {onse mkati kunja} ExampLe: Chipangizo# polojekiti kujambula epc-session1 mawonekedwe GigabitEthernet 0/0/1 onse |
Imakonza mawonekedwe a Gigabit Ethernet olowera, otuluka, kapena onse olowera ndi mapaketi otuluka. Gigabit ndi ya olamulira a Cisco 9800-CL, mwachitsanzoample, Gi1, Gi2, kapena Gi3. Kwa olamulira akuthupi, muyenera kufotokoza njira ya doko, ngati yakonzedwa. Eksamples kwa mawonekedwe akuthupi ndi Te kapena Tw. Zindikirani Mutha kuyendetsanso lamulo la ndege kuti mugwire punt ya paketi ku CPU. |
| Gawo 3 | (Mwasankha) fufuzani kujambula epc-session-name malire a nthawi malire-nthawi ExampLe: Chipangizo# sungani kujambula epc-session1 malire a nthawi ya 3600 |
Imakonza malire ojambulira, mumasekondi. |
| Gawo 4 | (Mwasankha) fufuzani kujambula epc-session-name chozungulira chozungulira file ayi-files file-kukula pa-file- kukula ExampLe: Chipangizo# sungani kujambula epc-session1 buffer mozungulira file 4 file- kukula 20 |
Imakonza ma file mu chozungulira chozungulira. (Buffer ikhoza kukhala yozungulira kapena yozungulira). Pamene chizungulire chikukonzedwa, chozungulira files amagwira ntchito ngati ring buffer. Mtengo wa nambala of files kukhazikitsidwa ndi kuchokera 2 mpaka 5. Mtengo wamtengo wapatali wa file kukula ukuchokera 1 MB kufika 500 MB. Pali mawu osakira osiyanasiyana omwe amapezeka pamalamulo a buffer, monga, zozungulira, file, ndi kukula. Apa, lamulo lozungulira ndilosankha. Zindikirani Chotchinga chozungulira ndichofunika kuti mugwire mosalekeza. Gawo ili limapanga kusinthana files mu controller. Sinthani files are not packet capture (PCAP) files, choncho, sitingathe kusanthula. Pamene lamulo la kutumiza kunja likuyendetsedwa, kusinthana files amaphatikizidwa ndikutumizidwa kunja ngati PCAP imodzi file. |
