Description: The type of interface counters the system is capable to do sorting on, as an extension to the interfaceTopNCaps defined in INTERFACETOPN-MIB.

utilization -- The interface bandwidth utilization in 32-bit version. The utilization on ethernet interface is computed in the following methods:

Ethernet utilization: (for full duplex interface, divide by 2)

10 Mbps I/O-pkts * (9.6 + 6.4) + (0.8 * I/O-Bytes) Ethernet Util = ----------------------------------------- Interval * 10,000

where 9.6 is interframe gap of Ethernet 6.4 is preamble of Ethernet 10,000 is 10Mbps

100 Mbps I/O-pkts * (96 + 64) + (8 * I/O-Bytes) Ethernet Util = -------------------------------------- Interval * 1,000,000

1000 Mbps I/O-pkts * (96 + 64) + (8 * I/O-Bytes) Ethernet Util = -------------------------------------- Interval * 10,000,000

10000Mbps I/O-pkts * (96 + 64) + (8 * I/O-Bytes) Ethernet Util = -------------------------------------- Interval * 100,000,000

All other I/O-pkts * (9.6 + 6.4) + (0.8 * I/O-Bytes) Ethernet Util = ------------------------------------------ Interval * N * 1,000 (where N is N Mbps)

bytes -- the total number of bytes received and transmitted on the interface in 64-bit version.

packets -- the total number of packets received and transmitted on the interface in 64-bit version.

broadcast -- the total number of broadcast packets received and transmitted on the interface in 64-bit version.

multicast -- the total number of multicast packets received and transmitted on the interface in 64-bit version.

overflow -- the total number of transmitted buffer overflow errors on the interface in 32-bit version.
