citneInterfaceTopNCaps 1.3.6.1.4.1.9.9.482.1.1

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.
