show bandwidth_control
Purpose Used to display the bandwidth control configuration on the Switch.
Syntax
show bandwidth_contr
ol {<portlist>}
Description The show bandwidth_control command displays the current bandwidth control configuration on the Switch, on
a port-by-port basis.
Parameters <portlist> – Specifies a range of ports to be configured.The port list is specified by listing the lowest switch
number and the beginning port number on that switch, separated by a colon.Then the highest switch number,
and the highest port number of the range (also separated by a colon) are specified.The beginning and end of
the port list range are separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies
switch number 2, port 4. 1:3-2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 – in
numerical order.
Using this command without adding a portlist entry will show the bandwidth control for all ports in the Switch
stack.
Restrictions None.
Example usage:
To display bandwidth control settings:
AT-9724TS:4# show bandwidth_control 1:1-1:10
Command: show bandwidth_control 1:1-1:10

config scheduling
Purpose Used to configure traffic scheduling for each of the Switch’s hardware priority classes.
Syntax config scheduling <class_id 0-6> {max_packet <value 0-15>}
Description The Switch contains seven hardware classes of service per device.The Switch’s default settings draw down
seven hardware classes of service in order, from the highest priority class (Class 6) to the lowest priority class
(Class 0). Starting with the highest priority class (Class 6), the highest priority class will transmit all of the
packets and empty its buffer before allowing the next lower priority class to transmit its packets.The next
highest priority class will empty before proceeding to the next class and so on. Lower priority classes are
allowed to transmit only if the higher priority classes in the buffer are completely emptied. Packets in the higher
priority classes are always emptied before any in the lower priority classes.
The default settings for QoS scheduling employ this strict priority scheme to empty priority classes.
The config scheduling command can be used to specify the weighted round-robin (WRR) rotation by
which these seven hardware priority classes of service are reduced.To use a weighted round-robin (WRR)
scheme, the max_packets parameters must not have a value of zero (0). (See Combination Queue below.)
The max_packet parameter allows you to specify the maximum number of packets a given priority class can
transmit per weighted round-robin (WRR) scheduling cycle.This provides for a controllable CoS behavior
while allowing for other classes to empty as well.A value between 0 and 15 packets can be specified per
priority queue.
