SNMP requests for Serial Numbers of Cisco Devices

Hi

I am trying to find out how it is possible to display values for a Cisco Host from a specfic table.

The Table is from Cisco ENTITY-MIB

entPhysicalEntry (OID:1.3.6.1.2.1.47.1.1.1.1)

In the end I would like to have a table of the Serial Number associated with this device/host, e.g.

entPhysicalDesc (OID:1.3.6.1.2.1.47.1.1.1.1.2)

entPhysicalName (OID:1.3.6.1.2.1.47.1.1.1.1.7)

entPhysicalModelName (OID:1.3.6.1.2.1.47.1.1.1.1.27)

enyPhysicalSerialNum (OID:1.3.6.1.2.1.47.1.1.1.1.13)

And if possible I would like to filter the results displaying only entries where the serial number is defined.

Any help would be mush appreciated.

Thanks
