The table is indexed by the MAC address and it is a read only table. So
I have added Private Mib parameter that takes the Key value
from the user as a set parameter. I am able to retrieve the details
of all the parameters for that key value and storing it into a structure.
I want to display these values but when I run the for loop for
requests, the request has the parameter details of the private MIB.
Is there anyway I display the single row for the SET request?
Ex.
Table X is read only table
It is indexed by MAC address.
Table Y = private Mib
"y" is Table Y parameter that is settable
"y" fetches the MAC address from the user and fetches the data
for that MAC address through Get a single row and
stores it in a "x" structure (this structure has all parameters
of Table X).
I want to display the Table X one row based on whatever I have
stored in "y" structure.
How to retrieve these in single row format??
