The SNMP ifXTable is presenting zeros for attributes hc_in_multicast_pkts and hc_out_multicast_pkts. However, this data is available on the Big-IP and should be presented.
Inability to characterize/view counts for the above-referenced multicast packets via SNMP.
snmpwalk the ifTable and the ifXTable. The ifTable shows Counter32 values for attributes in_multicast_pkts and out_multicast_pkts, but the ifXTable shows zeros for the Counter64 equivalent attributes hc_in_multicast_pkts and hc_out_multicast_pkts (except for vlans, which are correct).
None
The snmp walk described in the Symptom/Known issues field gives meaningful results after application of this hotfix.
