The syntax for ifPhysAddress is physAddress, which is a series of bytes in 
binary.

The fact that net-snmp (e.g. snmpwalk) decodes them and prints them nicely for 
you doesn't change the fact that what devmon receives over the network from 
the device is an octet string.

You probably need to do more transormation here, such as splitting 
ifPhysAddress into 6 octets, then converting each octet (so, at least 7 
transforms, possibly more).

You may want to look at the 'log' test in the compaq-server template.

In future, it may be worthwhile introducing a new transform which does all of 
this with one operator, but then it may make more sense switching to a 
different SNMP module which supports MIBs and has automatic syntax 
conversions.

Wrong ... it is presenting the MAC address, just not ina  human-readable form 
...
