Improvements to Interface Transmit Statistics Reporting
The offered load on an interface can be defined as the amount of data the interface is capable of transmitting during a given time period. However, the offered load is not always the same as the actual transmitted load because the offered load calculation does not take into account possible packet drop or traffic loss.
On MX Series devices, the logical interface-level statistics show only the offered load, which is often different from the actual transmitted load. To address this limitation, Junos OS introduces a new configuration option in Release 11.4 R3 and later. The new configuration option, interface-transmit-statistics at the [edit interface interface-name] hierarchy level, enables you to configure Junos OS to accurately capture and report the transmitted load on interfaces.
When the interface-transmit-statistics statement is included at the [edit interface interface-name] hierarchy level, the following operational mode commands report the actual transmitted load:
- show interface interface-name <detail | extensive>
- monitor interface interface-name
- show snmp mib get objectID.ifIndex
 | Note: This configuration is not supported on Enhanced IQ (IQE) and Enhanced IQ2 (IQ2E) PICs. |
The show interface interface-name command also shows whether the interface-transmit-statistics configuration is enabled or disabled on the interface.
