C2960G-48TC-L Packet Drops

Czesc,



Mam ciekawy przypadek i chcial bym dogrzebac sie do jakiejs sensownej odpowiedzi poniewaz teraz nie do konca pojmuje jak to jest mozliwe, jezeli macie jakies sensowne artykuly pdfy , chetnie przeczytam aby zrozumiec powod.

Mam Access switcha C2960G-48TC-L , nizej mozna zobaczyc ile menijwiecej mbp/s i kpps switch obsluguje, jak widac nie jest to wiele zwlaszcza w porownianiu z parametrami podanymi https://www.cisco.com/c/en/us/products/ ... 22c0c.html ( tak wiem uzyskana przepustowosc itd jest w labie i idealnych warunkach ) dlatego zawsze takie informacje dziele przez 2 przynajmniej.

Switch niema nic specjalnego skonfigurowanego , zwykle access porty i trunki do tego sa 2 span sesje dla IDS i bez QOS.

Zastanawia mnie dla czego taki switch dropuje pakiety jak pokazane na porcie 44 "Total output drops" , jest to destination SPAN port, malo tego gdy traffic sie zwieksza dropy zaczynaja byc widoczne na porcie podlaczonym to jednego z Firewall.

Przyjmujac ze gigowy port przesylal by tylko 1500 byte pakiety to musialby przeslac okolo 86000 pps na 1gbps.


Rozumiem ze switch ma dzialone buffery itd co przy malych burstach moze powodowac dropy .


Jesli macie jakies suggestie , dokumentacje odnosnie architectury kolejek bufferow itd chetnie przeczytam by lepiej zrozumiec problem , szukalem na necie lecz nie wiele znalazlem aby bylo dokladnie opisane.
