Cisco numeric value mibs can be polled and thresholded through NetView
or HPOV. The NetView and HPOV online-documentation, training materials, and
manuals explain this process in detail. This document gives an example of how
you can generate an event to go to the NetView/HPOV events area when
"ifInOctets" on Digdug (the router in this example) exceed 17000000.
There are no specific requirements for this document.

Complete these steps:
In order to go to the Data Collection and Threshold area, enter
xnmcollect from the command line, or Options (HPOV) and then
Data Collection and Thresholds, or Tools (NetView) and then Data Collection and
The MIB Data Collection window will come up.
Click the Add button in the middle right screen.
(On HPOV 4.x, this is Edit/Add/Mib Objects from the top
The Mib Data Collection/Mib Object Selection window will come
Click management and go down the tree to mib-2,
interfaces, ifTable, ifEntry, ifInOctets. With this highlighted, click
Describe in order to confirm that this is what you want. Then,
select close, and then ok.
Note: If this causes an error by being part of a canned collection, you
can choose something else.
The Mib Data Collection/Add Collection window will appear.
Enter the source router for collection (Digdug in this example) and
In the Collection Mode area, there are four options:
Choose Don't Store, Check Threshold and fill in
the polling interval. Choose 1h (hourly); the default trap
number is 58720263.
Fill in the value 17000000 for
The re-arm value is to indicate that after the trap is generated
when the threshold value is exceeded, it will not be generated again until
after the re-arm value is reached. Therefore, you fill in 16000000, so when
17000000 is exceeded, no more traps until dip to 16000000.
On instances, choose From List, then fill in
1 (i.e. ifIndex 1, your ethernet).
