Chapter  Configuration Using the Web-based Utility
4 24/48-Port 10/100 + 4-Port Gigabit Resilient Clustering Smart Switch with 2 Combo SFPs
Committed Information Rate (CIR) Defines CIR as
the queue shaping type. The allowed values are 4 to
200 Kbps for the 10/100 ports and 4 to 1000000 Kbps
for the Gigabit ports.
Committed Burst Size (CBS) Defines CBS as the
queue shaping type. The possible field value is 409
to 1,9,020 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  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 1 seconds. The
range is 4 to 0 seconds.
