Configuration Using the Web-based Utility

Committed Information Rate (CIR)  Defines CIR as the queue shaping type. The allowed values are 64 to 62500 Kbps for the 10/100 ports and 64 to 1000000 Kbps for the Gigabit ports.

Committed Burst Size (CBS)  Defines CBS as the queue shaping type.The possible field value is 4096 to 15769020 bits. Commited Burst Size cannot be configured on FE ports.

Click Add to List to add the Bandwidth configuration to the Bandwidth Table at the bottom of the screen.:

QoS > Basic Mode

QoS > Basic Mode

The Basic Mode screen contains the following fields:

Trust Mode  Displays the trust mode. If a packet’s CoS tag and DSCP tag are mapped to different queues, the Trust Mode determines the queue to which the packet is assigned. Possible values are:

•CoS  Sets trust mode to CoS on the device. The CoS mapping determines the packet queue

•DSCP  Sets trust mode to DSCP on the device. The DSCP mapping determines the packet queue.

Spanning Tree

Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path between end stations on a network, eliminating loops.

Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency.

The Switch supports the Classic STP version of STP, which provides a single path between end stations, avoiding and eliminating loops.

Spanning Tree > STP Status

The STP Status screen displays the STP status on the Switch. This information is read-only and cannot be modified.

Spanning Tree > STP Status

Spanning Tree State  Indicates whether STP is enabled on the device.

Spanning Tree Mode  The STP mode by which STP is enabled on the device.

Bridge ID  The Bridge priority and MAC address.

Designated Root  Identifies the bridge priority and MAC address of the root bridge.

Root Port  The port number that offers the lowest cost path from this bridge to the Root Bridge. It is significant when the Bridge is not the Root. The default is 0.

Root Path Cost  The cost of the path from this bridge to the root.

Root Maximum Age (sec)  The device Maximum Age Time, which indicates the amount of time in seconds a bridge waits before sending configuration messages. The default is 20 seconds. The range is 6 to 40 seconds.

Root Hello Time (sec)  The device Hello Time. The Hello Time indicates the amount of time in seconds a root bridge waits between configuration messages. The default is 2 seconds. The range is 1 to 10 seconds.

Root Forward delay (sec)  The device forward delay time. The Forward Delay Time indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 15 seconds. The range is 4 to 30 seconds.
