ExtremeWare XOS 11.5 Command Reference Guide
884
configure ports rate-limit packet byte-adjustment
configure ports <port_list> rate-limit packet byte-adjustment [increase
<add_bytes> | decrease <sub_bytes>]
Description
Configures the number of bytes to add to or subtract from each packet on the specified ports for
calculating the ingressing traffic rate, traffic utilization, and traffic statistics for HQoS.
Syntax Description
Default
0.
Usage Guidelines
With HQoS, use this command to specify the number of bytes to be added to or subtracted from all
packets ingressing the specified ports when calculating the ingressing traffic rate, traffic utilization, and
traffic statistics. You can add or subtract 1 to 4 bytes from each packet. To unconfigure this setting, re-
issue the command and enter the value 0.
To display the number of bytes added to or subtracted from each ingressing packet for calculating the
ingress traffic rate, traffic utilization, and traffic statistics, use the
show ports <port_list
information
detail command.
The following is sample output from this command (the setting is displayed on the Packet Length
Adjustment line):
show port 2:1 information detail
Port: 2:1
Virtual-router: VR-Default
Type: UTP
Random Early drop: Unsupported
Admin state: Enabled with auto-speed sensing auto-duplex
Link State: Active, 1Gbps, full-duplex
Link Counter: Up 8 time(s)
VLAN cfg:
Name: vman110, Internal Tag = 110, MAC-limit = No-limit, Virtual
router: VR-Default
STP cfg:
port_list
Specifies the port or ports that will have the specified bytes added to or subtracted from all
packets in calculating the ingressing traffic rate, traffic utilization, and traffic statistics.
add_bytes
Specifies the number of bytes to add to each packet when calculating the ingressing traffic
rate. The default number is 0; the available range of added bytes is 1 to 4.
sub_bytes
Specifies the number of bytes to subtract from each packet when calculating the ingressing
traffic rate. The default number is 0; the available range of subtracted bytes is 1 to 4.
