"Bu tanim yokken IOS BW'nin %75'ini senin kullanimina sunuyor" kismi frame-relay icin biraz degisik
Frame-relay QoS, her zaman, tanimli ise minCIRa , eger minCIR tanimli degilse CIR degerine gore calisir (CIR/2)...

Default %75 QoS diger interfaceler icin gecerli (ethernet/atm/ serial...)

icerisinde priority percent 70 diyorsun ve IOS sana %70 (yani 179kb) ayiramayacagini sadece %53 (yani (256-120)/256) kaldigini soyluyor.

durumlarda interface altindaki "max-reserved-bandwitdh" tanimlarina dikkat etmelisin. Bu tanim yokken IOS BW'nin %75'ini senin kullanimina sunuyor. Demek istedigim QoS-VoIP-Control-Trust class'in icin ayrilan BW "max-res-bw" tanimina gore degisir.
