Description
CAUTION:
Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.
Configure the properties of a specific integrated bridging and routing (IRB) interface.
The remaining statements are explained separately. See CLI Explorer.
Required Privilege Level
