Nortel Networks 350 manual describes the Rate Limiting Configuration screen fields, Packet Type

		Using the Console Interface
	Table 3-19 describes the Rate Limiting Configuration screen fields.
Table 3-19.	Rate Limiting Configuration Screen Fields
Field	Description
Port	Indicates the switch port numbers that correspond to the field settings in that row
	of the screen (for example, the field settings in row 2 apply to switch port 2). Note
	that the settings applied in the All row (bottom row) affect all switch ports.
Packet Type	Allows you to select the packet types for rate limiting or viewing.
	Default Value:	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*.
	Default Value:	None
	Range:	None, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%
Last 5 Minutes	This read-only field indicates the percentage of packets (of the type specified in
	the Packet Type field) received by the port in the last five minutes. This field
	provides a running average of network activity and is updated every 15 seconds.
	Note that this field indicates the receiving port’s view of network activity,
	regardless of the rate limiting setting.
Last Hour	This read-only field indicates the percentage of packets (of the type specified in
	the Packet Type field) received by the port in the last hour. This field provides a
	running average of network activity and is updated every five minutes.
	Note that this field indicates the receiving port’s view of network activity,
	regardless of the rate limiting setting.
Last 24 Hours	This read-only field indicates the percentage of packets (of the type specified in
	the Packet Type field) received by the port in the last 24 hours. This field provides
	a running average of network activity and is updated every hour.

Note that this field indicates the receiving port’s view of network activity, regardless of the rate limiting setting.

*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.
