New Network Metrics

The standard SNMP network management MIB for a network interface is supposed to contain IfInOctets and IfOutOctets counters that report the number of bytes input and output on the interface. These were not measured by network devices for Solaris 2, so the MIB always reported zero. Brian Wong and I filed bugs against all the different interfaces a few years ago, and bugs were filed more recently against the SNMP implementation. The result is that these counters have been added to the “le” and “hme” interfaces in Solaris 2.6, and the fix has been backported in patches for Solaris 2.5.1, as 103903-03 (le) and 104212-04 (hme).
