If someone can help me.
A device error mib tree is the following:
  >time, date, port and error code.

An other MIB tree contains the error codes with its description like this:

alrGenDescription.1 REAL TIME CLOCK BATTERY FAILURE
alrGenDescription.2 PS-A FAILURE
alrGenDescription.3 PS-A 12V FAILURE
alrGenDescription.4 PS-B FAILURE
alrGenDescription.5 PS-B 12V FAILURE

I would like to make a table, where I can see the error time, date, port and the error description (not error code).

I think, I have to make a mapping table with the error codes (1, REAL TIME CLOCK BATTERY FAILURE ..etc). But I cannot figure out, how to use it anyweher. No mention in documentation or example on the net.

Have you got any idea ?
