<br><font size=2 face="sans-serif">Hello,</font>
<br>
<br><font size=2 face="sans-serif">Occasionally I have a problem polling
data on one of my external Cisco routers. On the Internet-facing
interface, the Inbound data is zero, but the Outbound counter is working.
The reverse is same for my LAN-facing interface.</font>

zeros and that's what MRTG is graphing.</font>
