Configuring Port Mirroring
TheMatrixdeviceallowsyoutomirror(orredirect)thetrafficbeingswitchedonaportforthe
purposesofnetworktrafficanalysisandconnectionassurance.Whenportmirroringisenabled,
oneportbecomesamonitorportforanotherportwithinthedevice.
Supported Mirrors
ThefollowingtypesofportscanparticipateinmirroringontheMatrixSeriesdevice:
•Physicalports, includingfrontpanelandFTM‐1ports
•Virtualports,includingLinkAggregationGroup(LAG)andhostports.Fordetailson

Active Destination Port Configurations
EachMatrixDFE‐GoldSeriesdevicesupportsthreemirroringdestinationports,whichcanbe
configuredinamany‐to‐onemirroringconfiguration(thatis,manydestinationsmirroredtoone
sourceport).
Purpose
Toreviewandconfigureportmirroringonthedevice.
Commands
