Hello all,

has anyone been able to query the SNMP 64bit counters for network
interfaces on AIX 5.3 or 6.1? If i do a snmpwalk on the IF-MIB sub-
tree it seems that there are no entries for network interfaces:

# snmpwalk -v2c -c public <ip> .1.3.6.1.2.1.31
IF-MIB::ifMIB = NULL
# snmpwalk -v2c -c public <ip> .1.3.6.1.2.1.31.1
IF-MIB::ifMIBObjects = NULL
# snmpwalk -v2c -c public <ip> .1.3.6.1.2.1.31.1.1
IF-MIB::ifXTable = NULL
# snmpwalk -v2c -c public <ip> .1.3.6.1.2.1.31.1.1.1
IF-MIB::ifXEntry = NULL
# snmpwalk -v2c -c public <ip> .1.3.6.1.2.1.31.1.1.1.10
IF-MIB::ifHCOutOctets = Wrong Type (should be Counter64): NULL

The exact same subtree gives the correct 64bit counters on non-AIX
systems. Not being able to get ifHCOutOctets and ifHCInOctets is
pretty annoying on systems with interfaces >100MBit/s and a poll
interval of 5 minutes :-/

SNMPD is /usr/sbin/snmpdv3ne and /etc/mib.defs was expanded by the
mosy'ed definitions from IF-MIB. Is the AIX snmpd really _that_ broken
or am i missing something here?

Thanks & best regards,

Frank
