style='font-size:10.0pt;font-family:Verdana'>Dear all,<br>
<br>
Recently I was amazed to see few things in the devices I was using MRTG for.<br>
<br>
First, I have two cisco uBR 7200 with same IOS version and same model but the
OIDs in them for same datas to are to be retrieved are different in the leaf
OIDs whereas the branch OID is the same.<br>
<br>
i mean if 1.3.2.1.2.1.2.3.1.2.1.2 was for one than 1.3.2.1.2.1.2.3.1.2.1.9 was
for the other..<br>
<br>
Second thing is one of the device got automatically rebooted because of some
power failure lately, and i was unable to see MRTG graphs for few of the datas
polled. Upon further diagnose i found that the leaf OIDs have increased with
two <br>
<br>
i mean if 1.3.2.1.2.1.2.3.1.2.1.2 was the OID that was polled than after the
reboot it wasnt existing and 1.3.2.1.2.1.2.3.1.2.1.4 was the one that was
providing the necessary values.<br>
<br>
Has any one came across this type of situations before...please do share..<br>
<br>
Does the OIDs get changed so abnormally or is it because of some faults in the
device.<br>
<br>
TIA,<br>
<br>
