xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch NOTE: You cannot mirror a fast port onto a slower port. For example, if you try to mirror the traffic from a 100 Mbps port onto a 10 Mbps port, this can cause throughput problems. The port you are copying frames from should always support an equal or lower speed than the port to which you are sending the copies. Also, the target port for the mirroring cannot be a member of a trunk group. Please note a target port and a source port cannot be the same port. NOTE: When the device with the source port has been removed from a stack, the configuration will be disabled temporarily until another device has been installed in its place. If configurations are saved to NVR RAM during this period the configuration will be removed forever. Mirroring within the Switch Stack Users may configure mirroring between switches in the switch stack but certain conditions and restrictions apply. 1. When mirroring is configured in the stack, the primary master and the backup master will save and synchronize these mirroring configurations in their respective databases. Therefore, if the primary master is removed, the backup master will still hold the mirroring configurations set. 2. If the device hot-removed from the stack holds the target port for the mirroring function, the primary master will disable the mirroring function for the whole stack. 3. Stacking ports cannot be source ports or target mirror ports. 26
