• All QoS/CoS rules that apply to the destination port, as an egress, such as traffic shaping, are suspended for the duration of the mirroring session. Any such settings, configured on the port during the mirroring session, take effect only after the port is no longer a destination port for a mirroring session. • Ingress mirrored packets may arrive at the ingress port either with an 802.1q tag or without. When the packets are mirrored to a port analyzer, they should be transmitted as they are received on the ingress port. However, in the device, the packet is transmitted out of the port analyzer as always tagged or always untagged (user configurable), regardless of the input encapsulation. Source Port Restrictions The following restrictions apply to ports specified as source ports: • Source ports cannot be a member of a LAG. • Source ports cannot be configured as a destination port. • Up to eight source ports can be mirrored. NOTE: When a port is set to be a target port for a port-mirroring session, all normal operations on it are suspended. This includes Spanning Tree and LACP. All currently active protocols and services on that port are suspended. 412 Dell PowerConnect 55xx Systems User Guide
