want subtracted from each packet ingressing the specified ports or the number of bytes you 
want added to the packet ingressing the specified ports. 

You add or subtract bytes from packets ingressing specified ports by using the following 
command:

configure ports <port_list> rate-limit packet byte-adjustment [increase 

<add_bytes> | decrease <sub_bytes>]

By default, all bytes are counted for the ingressing traffic rate. After you issue this command, 
the default number of bytes removed is 0; you can add or subtract from 1 to 4 bytes from 
each ingressing packet on the specified ports for calculating the ingressing traffic rate.

To display the number of bytes added to or subtracted from the packet to calculate the 
ingressing traffic rate, traffic utilization, and traffic statistics, use the following command:

show ports <port_list> information detail

You must use the 

detail

 keyword to display this information.

To unconfigure this setting, re-issue the command and enter the value 0.

If you use this command to decrease by 4, the 

show traffic queue statistics

 display 

shows only bytes; the packets are displayed as 0.

Controlling Flooding, Multicast, and Broadcast Traffic on 

Ingress Ports

On NETGEAR 8800 series switches, you can use the following command to control ingress 
flooding of broadcast and multicast traffic and traffic for unknown destination MAC 
addresses:

configure ports <port_list> rate-limit flood [broadcast | multicast | 

unknown-destmac] [no-limit | <pps>]
