Enter the following information:
• VLAN ID—Select a VLAN.
• Committed Information Rate (CIR)—Enter the average maximum amount
of data that can be accepted into the specified interfaces in Kilobytes per

be bound to the selected VLAN.
Click Apply. The Running Configuration is updated.

Configuring TCP Congestion Avoidance

Use the TCP Congestion Avoidance page to activate a TCP congestion avoidance
algorithm. The algorithm breaks up or avoids TCP global synchronization in a
congested node, where the congestion is due to various sources sending packets
with the same byte count.
To configure TCP congestion avoidance:
Click Quality of Service > General > TCP Congestion Avoidance.
Click Enable to enable TCP congestion avoidance.
Click Apply. The Running Configuration is udpated.
