Field Description
Unit Indicates where the port resides:
• Base (for example, 1783-MS10T)
• Expansion module (for example, 1783-MX08T)
Port Indicates the port that is selected for configuration.
The port number includes the port type (Fa for Fast Ethernet and Gi for Gigabit Ethernet), the base or expansion module
number (1, 2, or 3), and the specific port number. For example:
• Gi1/1 is Gigabit Ethernet port 1 on the base.
• Fa2/1 is Fast Ethernet port 1 on the first expansion module.
Storm Control Threshold Settings Set the threshold values for the broadcast, unicast, and multicast traffic for each port. The number of packets being sent is
compared against the threshold value. If an undesirable network event occurs and the threshold value has been exceeded, a
Yes value appears on the Port Status view and in the Traffic Threshold Exceeded on Any Port field on the Switch Status view.
Network traffic of the type that exceeded threshold (broadcast, unicast, or multicast) is dropped until it falls below the falling
threshold. The falling threshold is automatically set to 5% less than the entered threshold value.
Broadcast, Unicast and Multicast Complete these fields for each traffic type:
• Enable—Check to enable the storm control on the selected port. The respective threshold value and units are applied to
the selected port when you click Set. Clear the checkbox to disable the storm control for the selected port. Zero is applied
to the threshold value and units attributes when you click Set.
• Threshold—Type the value for the threshold after you choose the unit of measurement:
– If Units is set to pps or bps, type a value between 0…10000000000.
– If Units is set to %, type a value between 0…100.
• Units—Choose the unit of measurement for the threshold:
– pps (packets per second)
– bps (bits per second)
– %
