Bonjour, J’ai un problème d’incompréhension des résultats suivants effectués avec IPERF et un switch cisco ayant un service-policy sur les ports de tests. 192.168.0.160 : Test limité à 1M 192.168.0.170 : Test limité à 0.5M, 1M et 10M interface f0/X service-policy input policy_ip Le test 2 et 3 me semble bon mais pas le 4 !!?? -> Test 1 (100M) : Pas de limitation (pas de police activé pour les ports du switch) ------------------------------------------------------------ Client connecting to 192.168.0.160, TCP port 5001 TCP window size: 80.6 KByte (default) ------------------------------------------------------------ [ 5] local 192.168.0.170 port 54551 connected with 192.168.0.160 port 5001 [ ID] Interval Transfer Bandwidth [ 5] 0.0-10.0 sec 113 MBytes 94.8 Mbits/sec [ 4] local 192.168.0.170 port 5001 connected with 192.168.0.160 port 50460 [ 4] 0.0-10.1 sec 113 MBytes 94.1 Mbits/sec
