Operation Manual – Port MirroringH3C S5500-EI Series Ethernet Switches Chapter 1 Port Mirroring Configuration1-3z Destination deviceDestination device contains destination mirroring port, and remote destination portmirroring groups are created on destination devices. Upon receiving a mirrored packet,the destination device checks to see if the VLAN ID of the received packet is the sameas that of the remote mirroring VLAN of the remote destination port mirroring group. Ifyes, the destination device forwards the packet to the monitoring device through thedestination mirroring port.1.1.3 Other Functions Supported by Port MirroringIn addition, in a port mirroring group, a destination port can monitor multiple sourceports simultaneously in the mirroring group.1.2 Configuring Local Port MirroringFollow these steps to configure local port mirroring:To do… Use the command… RemarksEnter system view system-view —Create a local mirroringgroupmirroring-group group-idlocal RequiredIn systemviewmirroring-group group-idmirroring-portmirroring-port-list { both |inbound | outbound }interface interface-typeinterface-number[ mirroring-group group-id ]mirroring-port { both |inbound | outbound }Add portsto the portmirroringgroup assourceportsIninterfaceviewquitUse either approach.You can add ports to aport mirroring group assource ports in eithersystem view orinterface view.In system view, youcan add multiple portsto a port mirroringgroup at one time.While in interface view,you can only add thecurrent port to a portmirroring group.In systemviewmirroring-group group-idmonitor-port monitor-port-idinterface interface-typeinterface-numberAdd a portto themirroringgroup asthedestinationportIninterfaceview [ mirroring-group group-id ]monitor-portUse either approach.You can add adestination port to aport mirroring group ineither system view orinterface view.
