Karolo ea Embedded Packet Capture e ea ntlafatsoa ho ts'ehetsa boholo bo eketsehileng ba buffer, ho ts'oaroa ho tsoelang pele, le ho sefa ha liaterese tse ngata tsa MAC ho Embedded e le 'ngoe. Seboka sa Packet Capture (EPC). |
Tlhahisoleseding mabapi le Embedded Packet Capture
Sebopeho sa Embedded Packet Capture se thusa ho latella le ho rarolla lipakete. Embedded Packet Capture ho controller e sebelisetsoa ho rarolla mathata a mangata, joalo ka, litaba tsa netefatso ka RADIUS, ho ikopanya le AP kapa ho khaoha, ho fetisoa ha bareki, ho khaola, le ho solla, le likarolo tse ling tse kang multicast, mDNS, sekhele, mobility, le joalo-joalo.Tlhahiso ena e lumella batsamaisi ba marang-rang ho hapa lipakete tsa data tse phallang, ho ea, le ho tloha sesebelisoa sa Cisco. Ha u rarolla bothata ba ho ikopanya le AP kapa bothata ba bareki ba ho kena, haeba u sa khone ho emisa ho ts'oara hang ha bothata bo hlaha, lintlha tsa bohlokoa li ka lahleha. Maemong a mangata, buffer ea 100 MB ha e lekane bakeng sa ho hapa data. Ho feta moo, karolo e teng ea Embedded Packet Capture e ts'ehetsa feela ho sefa ha aterese e le 'ngoe ea kahare ea MAC, e hapang sephethephethe sa moreki ea itseng. Ka linako tse ling, ho thata ho supa hore na ke moreki ofe ea se nang mohala o tobaneng le bothata.
Ho tloha ho Cisco IOS XE Dublin 17.12.1, karolo ea Embedded Packet Capture e ts'ehetsa boholo bo eketsehileng ba buffer, ho ts'oaroa ho tsoelang pele, le ho sefa ha liaterese tse ngata tsa MAC sebokeng se le seng sa Embedded Packet Capture. Ha ho na mehato ea GUI ea ho hlophisa ntlafatso ea Embedded Packet Capture.
Ho Hlophisa Pakete e Kenyellelitsoeng Capture (CLI)
Ka ntlafatso ea karolo ea Embedded Packet Capture, boholo ba buffer bo eketseha ho tloha ho 100 MB ho isa ho 500 MB.
