      We would like to monitor our Brocade Access Gateway switches with SNMP. It appears the all the critical counter we would like to monitor are available in the MIB and can be retrieved with a SNMPWALK or GET. The issue is that all the responses coming back from the needed switch OIDs in the form of a HEX-STRING like this:

      16:03:21 # snmpwalk -O e -v 1 -c <community> <hostname>
      SNMPv2-SMI::experimental. = Hex-STRING: 00 00 00 01 01 53 53 FC

      OpenNMS will walk the OID and get a response from the switch in the Hex-STRING format is seen above, we have confirmed that with a TCPdump trace and Wire Shark. We have made several adjustment to the snmpdatacollection.xml config file but none of the adjustments has changed the result.
