99NOTE:A mirroring group can contain multiple source CPUs.Configuring the monitor port for a local mirroring groupOn the source device, configure the tunnel interface as the monitor port; on the destination device,configure the port that connects the data monitoring device as the monitor port.You can configure the monitor port for a mirroring group in system view, or assign the current port to amirroring group as the monitor port in interface view. The two methods lead to the same result.Configuring the monitor port in system viewFollow these steps to configure the monitor port for a local mirroring group in system view:To do… Use the command… RemarksEnter system view system-view —Configure the monitor port mirroring-group group-idmonitor-port monitor-port-idRequiredBy default, no monitor port is configured fora local mirroring group.Configuring the monitor port in interface viewFollow these steps to configure the monitor port for a local mirroring group in interface view:To do… Use the command… RemarksEnter system view system-view —Enter interface view interface interface-typeinterface-number —Configure the current port asthe monitor port[ mirroring-group group-id ]monitor-portRequiredBy default, a port does not serve as themonitor port for any local mirroring group.NOTE:• A mirroring group contains only one monitor port.• To make sure that the mirroring function works properly, do not enable the spanning tree feature on themonitor port.• H3C recommends that you use a monitor port only for port mirroring. This is to make sure that the datamonitoring device receives and analyzes only the mirrored traffic rather than a mix of mirrored trafficand normally forwarded traffic.• You cannot configure the monitor port in a mirroring group as a port in a RRPP ring.Displaying and maintaining port mirroringTo do… Use the command… RemarksDisplay the configurationof mirroring groupsdisplay mirroring-group { group-id | all | local |remote-destination | remote-source } [ | { begin |exclude | include } regular-expression ]Available in any view
