Table 3-27. Rate Limiting Configuration Screen Fields
Field Description
Unit Appears only if the switch is participating in a stack configuration. The field allows
you to select the number of the unit you want to view or configure. To view or
configure another unit, type its unit number and press [Enter], or press the
spacebar on your keyboard to toggle the unit numbers.
Port Indicates the switch port numbers that correspond to the field values in that row of
the screen (for example, the field values in row 2 apply to switch port 2). Note that
the values applied in the Switch or Stack row (last 2 rows) affect all standalone
switch ports or all switch ports in a stack.
Packet Type Allows you to select the packet types for rate limiting or viewing.
Default Both
Range Both, Multicast, Broadcast
Limit Sets the percentage of port bandwidth allowed for forwarding the packet types
specified in the Packet Type field. When the threshold is exceeded, any additional
packets (specified in the Packet Type field) are discarded

Rate limiting is disabled if this field is set to None. This allows you to select and view the percentage of specific packet
types present in the network, without inadvertently limiting the forwarding rate.
