NetSnmp on AIX5.2 Can not get Host Info?

[tango . tang]

In Redhat9 default Netsnmp, we can get SystemName,PhyMemSize,AllocatedStorageSize,UsedStorageSize,
Volume Size and Volume FreeSpace etc.

While by NetSnmp5.2 on AIX5.2, we can only get SystemName.

>From the interface of Netsnmp we do can get all the above information,
also the netsnmp on Redhat 9 can get them.

The configuration in snmpd.conf on Redhat and AIX are the same.
Why the result is so different? Can I get the Host information by netsnmp on AIX?


Thanks,
