over the course of days.<br>
<br>
A cron job running once an hour would work, but snmp polling with<br>
mrtg, parsing the tc output would be better.<br>
<br>
But a quick survey would be interesting, if you could dump your<br>

uptime<br>
tc -s qdisc show dev whatever<br>
tc -s qdisc show dev your_inbound_ifb_device<br>
<br>
here?<br>
<br>
and also check to see if you are getting drops or marks on your core<br>
wifi interfaces. For example a great deal of the dropping behavior for<br>
me has moved to wifi over the last year (as we upgraded from 20mbit<br>
down to 60 or 110mbit down), particularly on my longer distance links<br>
but also on links that have very good same room connectivity.<br>
