Check that the ifOutOctets counter is actually increasing - MRTG
graphs the rate of increase, so possibly the rate is zero. The number
looks rather small.
Measured with an interval of 5 minutes.

Check that the rate of increase is not greater than AbsMax (100Mbps),
since if it is, it will be ignored.
On this interface can not pass more than 5 MB/s. Of this I am sure.
If the device supports SNMPv2, use that by having the :::::2 suffix on
the target --
Targets[xxxx_8]: 8:public@xxxx:::::2
Some SNMP agents support v1 or v2c correctly but not the other.

Apparently SNMPv2 not supported by the remote device. Incidentally, it
is not CISCO device, is Linux server.
