32.4 Device Mirror Troubleshooting

If problems occur on configuring port mirroring, please check the following first for causes:

Whether the mirror destination port is a member of a TRUNK group or not, if yes, modify the
TRUNK group.

If the throughput of mirror destination port is smaller than the total throughput of mirror source
port(s), the destination port will not be able to duplicate all source port traffic; please decrease the
number of source ports, duplicate traffic for one direction only or choose a port with greater
throughput as the destination port. Mirror destination port can not be pulled into Isolate vlan, or will
affect mirror between VLAN.
