Configuration Check
===============

mughie @ root: / # q_checkcfg / etc/htb/eth0-qos.cfg
Default bandwidth: 8

Class class_1, CIR: 2048, MIR: 2048
** 4 clients, CIR2: 2048, MIR2: 2048

1 classes; CIR / MIR = 2048 / 2048; CIR2 / MIR2 = 2048 / 2048

mughie @ root: / # q_checkcfg / etc/htb/eth1-qos.cfg
