commandes de diagnostiques

Question

Bonjour, 
je sollicite votre aide pour avoir un site montant un ensemble de commandes me permettant de diagnostique un problème sur mon routeur cisco 877 k9.
par exemple comment voir les connexions http, le débit descendant/montant, la bande passante etc.

l'idée est que les utilisateurs font des téléchargements qui ralentissant la connexion et je voudrais si possible savoir qui utilise un BD élevée et supprimer sa connexion.
merci.


Configuration: Windows / Chrome 61.0.3163.100

Bonjour ,
Pour la bande passante vous pouvez voir ici :

Merci MPMP10 mais ce que je chercher c'est d'afficher les informations réçu par le routeur.

salut,
pour le débit, un show interface tout simplement paramètres txload et rxload (fonction de la config du paramètre bandwith)
ainsi que input rate et output rate:
FastEthernet8 is up, line protocol is up   Hardware is FastEthernet, address is 001a.6cc1.1c9b (bia 001a.6cc1.1c9b)  MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,      reliability 255/255, txload 1/255, rxload 1/255  Encapsulation ARPA, loopback not set  Keepalive set (10 sec)  Full-duplex, 100Mb/s  ARP type: ARPA, ARP Timeout 04:00:00  Last input never, output never, output hang never  Last clearing of "show interface" counters never  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0  Queueing strategy: fifo  Output queue: 0/40 (size/max)  5 minute input rate 4000 bits/sec, 3 packets/sec  5 minute output rate 9000 bits/sec, 4 packets/sec     17443128 packets input, 2814419692 bytes, 0 no buffer     Received 24406 broadcasts, 0 runts, 0 giants, 0 throttles     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored     0 input packets with dribble condition detected     26472230 packets output, 3274487511 bytes, 0 underruns     0 output errors, 0 collisions, 2 interface resets     0 unknown protocol drops     0 babbles, 0 late collision, 0 deferred     0 lost carrier, 0 no carrier
Après,
pour les détails par utilisateur, il faut une sonde rmon ou pc genre ntop, l'idéal serait de la mettre sur un port switch libre du 877 et de faire du port mirroring du port lan vers le réseau local:
monitor session ....

 
et ... Voili  Voilou  Voila !
