I am having problems reporting on a Cisco 2924 switch. I had MRTG setup
and running on a previous Cisco switch, but it died and now I can't get
this one working correctly.
=20
I have SNMP configured on the switch with the following config line:
snmp-server community ninthbrain RO
=20
I used the following command to generate my mrtg.cfg file:
cfgmaker --output=3Dmrtg.cfg ninthbrain@{IP ADDRESS OF SWITCH}
=20
I then updated the WorkDir line manually. I also setup cron to run the
mrtg command on the cfg file with a 5 minute interval.
=20
At this point, MRTG seems to working correctly. There are no errors and
the log files are collecting data.
=20
The problem however, is the data the log files are collecting. All of
my ports are reporting the same data and all of my graphs are a flat
line at about 35 b/s.
An example from one of my log files is:
1209865204 102168435 1664983983
1209865204 0 35 0 35
1209864905 0 35 0 35
1209864900 0 35 0 35
..... (the rest of the lines are all 0 35 0 35)
=20
=20
Has anyone had this problem??? Any ideas on how to fix it? I only found
one other post with a similar problem, but no solution mentioned.
