9. Port mirroring allows you to duplicate all of the traffic going to one or more ports on to your monitoring port This is typically used for diagnosing and troubleshooting problems on the network For example if port 1 is the monitoring port and ports 2 and 3 are monitored ports then all traffic going to ports 2 and 3 will be copied to port 1 Note When using port mirroring you should avoid setting a port to be a monitoring port and an aggregated port at the same time to avoid conflicts 23 Mirror O mode IDET Monitoring 1M 2M 34 sM oM y Mg H Figure 3 13 Port Mirroring Page Mode Used to Enable or Disable port mirroring Default is Disable Monitoring Port Set the port that will be monitoring the other ports Default is Port 1 Monitored Port Set the port s to be monitored Place an X beside the number of the port s to monitor The Monitoring port should not be selected as a Monitored port 3 4 Bandwidth Management The Bandwidth Management page Figure 3 14 allows you to set both incoming and outgoing bandwidth limitations for each port Note Each port on the switch has its own 16KB packet buffer The packet buffer size will be reduced when the bandwidth rate limitation is enabled which may cause jumbo frames not to be forwarded Jumbo frames should not be used in conjunction with bandwidth limitations Bandwidth Management Configuration Port Number F Ingress Rate Limiting Policing Data
