Feature History for Embedded Packet Capture

Tafura iyi inopa kuburitswa uye ruzivo rwakabatana nezvechinhu chinotsanangurwa muchikamu chino. Iyi ficha inowanikwawo mune zvese zvinoburitswa zvinoteera kune iyo yavanounzwa mairi, kunze kwekunge zvaonekwa neimwe nzira.

Tafura 1: Feature History for Embedded Packet Capture

Kusunungurwa	Feature	Feature Information
Cisco IOS XE Dublin 17.12.1	Embedded Packet Capture	Iyo Embedded Packet Capture ficha inokwidziridzwa kutsigira yakawedzera buffer saizi, kuenderera kubatwa, uye kusefa kweakawanda MAC kero mune imwe Embedded. Packet Capture (EPC) chikamu.

Ruzivo Nezve Embedded Packet Capture

Iyo Embedded Packet Capture ficha inobatsira mukutsvaga uye kugadzirisa matambudziko mapaketi. Iyo Embedded Packet Capture pane controller inoshandiswa kugadzirisa nyaya dzakawanda, senge, nyaya dzechokwadi neRADIUS, AP kujoinha kana kudimbura, kuendesa mutengi, kubviswa, uye kutenderera, uye zvimwe zvinhu zvakaita semulticast, mDNS, amburera, kufamba, uye. so on.This feature inobvumira manetiweki administrator kutora data packets inoyerera kuburikidza, kuenda, uye kubva Cisco mudziyo. Paunenge uchigadzirisa AP kujoinha kana mutengi ari paboarding nyaya, kana ukatadza kumisa kubata kana nyaya yangoitika, ruzivo rwakakosha runogona kurasika. Kazhinji, buffer ye100 MB haina kukwana kutorwa kwedata. Zvakare, iyo iripo Embedded Packet Capture ficha inotsigira chete kusefa kweimwe yemukati MAC kero, iyo inobata traffic yemutengi chaiwo. Dzimwe nguva, zvakaoma kupinza-inongedza kuti ndeupi mutengi asina waya ari kutarisana nenyaya.

Kubva kuCisco IOS XE Dublin 17.12.1, iyo Embedded Packet Capture chimiro chinotsigira saizi yebhafa yakawedzera, kuenderera kunotora, uye kusefa kwemakero akawanda eMAC mune imwe Embedded Packet Capture session. Iko hakuna GUI matanho ekugadzirisa iyo Embedded Packet Capture yekusimudzira.

Kugadzirisa Embedded Packet Capture (CLI)

Iine Embedded Packet Capture chimiro chekusimudzira, saizi yebhafa inowedzerwa kubva pa100 MB kusvika pa500 MB.

  Cherechedza
Buffer ndeyemhando yendangariro. Unogona kuchengetedza memory buffer kana kukopa memory buffer iripo mu a file kuchengetedza mamwe mashoko.

Maitiro

	Raira kana Chiito	Chinangwa
Danho 1	Example: enable Chishandiso> gonesa	Inogonesa yakasarudzika EXEC modhi. Isa password yako, kana wakurudzirwa.
Danho 2	tarisa kubata epc-session-zita interface GigabitEthernet interface-nhamba {zvose mukati kunze} Example: Mudziyo# tarisa kubata epc-session1 interface GigabitEthernet 0/0/1 zvese	Inogadzirisa iyo Gigabit Ethernet interface yeinopinda, inobuda, kana zvese zviri mukati uye outbound packets. Gigabit ndeyeCisco 9800-CL controllers, kune example, Gi1, Gi2, kana Gi3. Kune vatongi venyama, unofanirwa kutsanangura chiteshi chechiteshi, kana chakagadzirirwa. ExampLes for physical interfaces vari Te kana Tw. Cherechedza Iwe unogona zvakare kumhanyisa iyo control-ndege yekuraira kutora iyo packet punt kuCPU.
Danho 3	(Sarudzo) tarisa kutora epc-session-zita muganhu wenguva muganhu-nguva Example: Chishandiso# tarisa kutora epc-session1 muganhu wenguva 3600	Inogadzirisa yekutarisa yekutora muganho, mumasekonzi.
Danho 4	(Sarudzo) tarisa kutora epc-session-zita buffer denderedzwa file kwete-ye-files file-saizi pa-file-saizi Example: Mudziyo# tarisa kutora epc-session1 buffer denderedzwa file 4 file- saizi 20	Configures the file mudenderedzwa buffer. (Buffer inogona kuita denderedzwa kana mutsara). Kana denderedzwa yakagadziriswa, iyo files basa seringi buffer. Kukosha kwehuwandu hwenhamba of files ichagadziriswa inobva ku2 kusvika ku5. Kukosha kwehuwandu hwe file saizi kubva 1 MB kusvika 500 MB. Kune akasiyana mazwi akakosha anowanikwa kune buffer command, senge, denderedzwa, file, uye saizi. Pano, iyo denderedzwa command ndeyekusarudza. Cherechedza Circular buffer inodiwa kuti urambe uchibatwa. Iyi nhanho inogadzira shanduko files mune controller. Swap files haisi packet capture (PCAP) files, uye naizvozvo, haigoni kuongororwa. Kana iyo ekisipoti command inoitwa, iyo swap files inosanganiswa uye inotumirwa kunze sePCAP imwe file.
Danho 5	tarisa kutora epc-session-zita mechi {chero | ipv4 | ipv6 | mac | pklen-range} Example: Chishandiso# chekutarisa kutora epc-session1 mechi chero	Inogadzirisa mafirita emukati. Cherechedza Unogona kugadzirisa mafirita uye ACLs.
Danho 6	(Sarudzo) tarisa kutora epc-session-zita access-list access-list-zita Example: Chishandiso# tarisa kutora epc-session1 kuwana-rondedzero yekuwana-rondedzero1	Inogadzirisa kubatwa kwemonita kunotsanangura runyoro rwekuwana sesefa yekutora packet.
Danho 7	(Sarudzo) tarisa kutora epc-session-zita kuenderera-kutora http:nzvimbo/filezita Example: Chishandiso# tarisa kutora epc-session1 inoenderera-kutora https://www.cisco.com/epc1.pcap	Inogadzirisa kuenderera kwepacket kutorwa. Inogonesa kutumira kunze kwenyika kwe files kune chaiyo nzvimbo buffer isati yanyorwa. Cherechedza • Buffer yedenderedzwa inodiwa kuti urambe uchitora. • Gadzirisa iyo filezita rine .pcap extension. • Mumwe muenzanisoample ye filezita uye nomenclature inoshandiswa kugadzira iyo filezita rakadai: CONTINUOUS_CAP_20230601130203.pcap CONTINUOUS_CAP_20230601130240.pcap • Mushure mekunge mapaketi aendeswa kunze otomatiki, buffer haina kucheneswa kudzamara yanyorwa nemapaketi matsva ekutora anouya, kana kucheneswa, kana kudzima mirairo.
Danho 8	(Sarudzo) [kwete] tarisa kutora epc-session-zita remukati mac MAC1 [MAC2… MAC10] Example: Chishandiso# tarisa kutora epc-session1 yemukati mac 1.1.1 2.2.2 3.3.3 4.4.4	Inogadzirisa anosvika gumi MAC kero semukati MAC sefa. Cherechedza • Iwe haugone kushandura maMAC emukati apo kutorwa kuri kuitika. • Unogona kuisa kero dzeMAC mumurairo mumwe chete kana kushandisa mitsara yakawanda yemirairo. Nekuda kweiyo tambo tambo kudzikisira, unogona kuisa mashanu chete MAC kero mune imwechete command line. Unogona kuisa asara ekero dzeMAC mumutsara unotevera wekuraira. • Kana nhamba yemakero emukati meMAC akagadziridzwa ari gumi, kero itsva yeMAC haigone kugadzirwa kusvikira wadzima kero yekare yemukati meMAC.
Danho 9	tarisa kutora epc-session-zita kutanga Example: Chishandiso# hapana chekutarisa kutora epc-session1 kutanga	Inotanga kutora data yepakiti.
Danho 10	tarisa kutora epc-session-zita kumira Example: Chishandiso# hapana chekutarisa kutora epc-session1 kumira	Inomisa kutorwa kwepacket data.
Danho 11	tarisa kutora epc-session-zita kunze filenzvimbo/filezita Example: Chishandiso# tarisa kutora epc-session1 kutumira kunze https://www.cisco.com/ecap-file.pcap	Exports yakatorwa data kuti iongororwe kana kuenderera mberi kutorwa kusina kugadzirwa.
