Note: IGMP mirroring functionality (igmp-mcast) is not supported on N-Series Gold devices.
Note: If you configure a port mirror on an uplink (tagged) port, make sure the port is assigned to
egress frames with that VLAN tag. For more information about configuring VLANs, refer to your
product’s Configuration Guide.
Notes: VLAN, IDS, and LAG mirroring are not supported on the X-Series.
