Issue/Introduction
You need to import some MIBs. As example, he is importing these MIBs, snmpv2-smi.mib and snmp-framework-mib.mib, under "Settings>All Settings>Monitoring and Alerting>SNMP MIB Import Browser>MIB Browser>Import MIB File"
Although the SMP Console reports success when importing MIBs, they are not actually being imported.
These are some of the messages you may find in the NS logs:
Entry 1:
MibImport: Value cannot be null.

Cause
An invalid MIB file was used originally to be imported. This appears to be a problem with data for import.
Note: our code can't generate anything for import from provided file and tried to import a 'null' instead of XML data.
Resolution
1. In this particular scenario, check the content of the MIB file is not a blank file. Check that it doesn't contain only comments without data.

2. Find a valid MIB file to be imported. For example, since we are trying to import "SNMPv2-SMI.mib", you can find a copy of it online. Search for it.
Here is one example:
SNMPv2-SMI DEFINITIONS ::= BEGIN
-- the path to the root
org OBJECT IDENTIFIER ::= { iso 3 } -- "iso" = 1
dod OBJECT IDENTIFIER ::= { org 6 }
internet OBJECT IDENTIFIER ::= { dod 1 }

mgmt OBJECT IDENTIFIER ::= { internet 2 }
mib-2 OBJECT IDENTIFIER ::= { mgmt 1 }
transmission OBJECT IDENTIFIER ::= { mib-2 10 }
experimental OBJECT IDENTIFIER ::= { internet 3 }
private OBJECT IDENTIFIER ::= { internet 4 }
enterprises OBJECT IDENTIFIER ::= { private 1 }
security OBJECT IDENTIFIER ::= { internet 5 }
snmpV2 OBJECT IDENTIFIER ::= { internet 6 }
-- transport domains
snmpDomains OBJECT IDENTIFIER ::= { snmpV2 1 }
-- transport proxies
snmpProxys OBJECT IDENTIFIER ::= { snmpV2 2 }
-- module identities
snmpModules OBJECT IDENTIFIER ::= { snmpV2 3 }
-- Extended UTCTime, to allow dates with four-digit years
-- (Note that this definition of ExtUTCTime is not to be IMPORTed
-- by MIB modules.)
ExtUTCTime ::= OCTET STRING(SIZE(11 | 13))
-- format is YYMMDDHHMMZ or YYYYMMDDHHMMZ
-- where: YY - last two digits of year (only years
-- between 1900-1999)
-- YYYY - last four digits of the year (any year)
-- MM - month (01 through 12)
-- DD - day of month (01 through 31)
-- HH - hours (00 through 23)
-- MM - minutes (00 through 59)
-- Z - denotes GMT (the ASCII character Z)
--
-- For example, "9502192015Z" and "199502192015Z" represent
-- 8:15pm GMT on 19 February 1995. Years after 1999 must use
-- the four digit year format. Years 1900-1999 may use the
-- two or four digit format.

We can import MIBs to be used with Network Discovery.
These MIBs usually consist of both “.mib” and “.my” files.
In the MIB Browser under “Settings > All Settings > Monitoring and Alerting > SNMP MIB Import Browser > MIB Browser”, you can import any of the “.mib” files. And they should be usable after the import.
You can as well use the MIB Import task, under “Manage > Jobs / Tasks > right click any folder > select New > Task > scroll down to and select “MIB Import” under "Monitoring and Alerting”, you can import both the “.mib” and “.my” files.
They will both be imported into the “Program Files\Altiris\MibImportTask\Mibs\Uploaded” folder.
You should also be able to select one of the MIB files within the “SNMP Data Mapping Tables”, “Settings > All Settings > Discovery and Inventory > SNMP Settings”
How to import a MIB file:
1. Find the MIB under the “Settings > All Settings > Discovery and Inventory > SNMP Settings > SNMP Data Mapping Tables”
2. Click on "New", and assign some name
3. Then, click "New" and give some Name and Length value and click on "Select OID"
4. Then, under MIB drop-down, see if those MIBs are listed or not. If so, select one.
5. Then, click on "iso" and you should be able to find/see the proper objects.
