another switch port. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusion-detection system.

Mirroring Configuration

Mirror Source: The port that will duplicate, or “mirror,” the traffic on the source port. Only incoming packets can be mirrored. Packets will be dropped when the available egress bandwidth is less than the ingress bandwidth.

Mirror Port: Select the ports that you want to mirror, then click Apply.

Quality of Service

Quality of Service (QoS) enhances communication quality by giving precedence to certain classes of packets. This switch provides QoS Disabled, 802.1p and DSCP modes.

QoS Configuration

Strict: Services the egress queues in sequential order, transmitting all traffic in the higher-priority queues before servicing lower-priority queues.

WRR: Weighted Round-Robin shares bandwidth at the egress ports by using scheduling weights with default values of 1, 2, 4, 8 for queues 0 through 7, respectively. (This is the default selection.) NOTE: WRR can only be selected if Jumbo Frame mode is disabled on the Port Configuration screen.

QoS Mode: 802.1p

Packets are prioritized using the 802.1p field in the VLAN tag. This field is three bits long, representing the values 0 - 7. When the QoS Mode is set to 802.1p, the 802.1p Configuration table appears, allowing you to map each of the eight 802.1p values to a local priority queue (low, normal, medium or high). The default settings are shown below.
