Buongiorno a tutti... ho scoperto questo forum per caso... facendo delle ricerche su internet su come fare alcune configurazioni su apparati Cisco..
complimenti! gran bel forum e molto utile

dunque vi espongo il mio quesito:

ho un router Cisco 837 al quale sono collegati 3 PC e un ATA 186 con un telefono analogico.
tutto funziona regolarmente, ovvero i PC navigano e scaricano regolarmente e anche le telefonate vanno senza problemi. l'unico problema che si verifica è che quando la banda viene saturata dagli altri 3 PC in download/upload le telefonate hanno un degrado della qualità, ovvero si sente a scatti.

è ovvio che avendo un'adsl 4096/256 con 200 Kb garantiti è facile che i 3 pc saturino la banda.
Come soluzione credo sia ottima configurare il QoS sul router. cosa ne pensate? qualche dritta su come configurare il QoS... sono abbastanza all'asciutto sul QoS

grazie mille per i consigli

di seguito allego lo "sh ver" del router

Ciao e benvenuto, come prima cosa hai una ios moolto vecchia (c837-k9o3y6-mz.123-2.XC2.bin) quindi aggiornala alla ultima compatibile.

Una volta aggirnata la ios con la plus la config del qos nn è tr complicata e ci sn un tot di discussioni in cui spiego come fare.

Cmq, intanto, aggiorna il router

vista la ram e la flash che ha il router l'unica compatibile è questa:

IP/FW/PLUS 3DES
c837-k9o3sy6-mz.123-11.YZ2.bin
Release Date: 13/Aug/2007

so che è vecchiotta ma penso vada bene comunque... giusto?


grazie
