DGS-3627:admin#
config scheduling
Purpose
Used to configure the traffic scheduling mechanism for each CoS queue.
Syntax
config scheduling {ports [<portlist> | all ]} <class_id 0-6>
[max_packet <value 0-15>]
Description
Used to configure the traffic scheduling mechanism for each CoS queue.
Parameters
ports <portlist>
- Specifies the range of ports to be configured.
all - To set all ports in the system, you may use the “all” parameter. If no parameter is
specified, the system will set all ports.
class_id
- This specifies the n+1 hardware priority queues that the config scheduling
command will apply to. The four hardware priority queues are identified by a number
from
0 to n
with the 0 queue being the lowest priority. The determination of n is project
dependent.
max_packet
- Specifies the maximum number of packets that the hardware priority queue,
specified above, will be allowed to transmit before allowing the next lowest priority queue to
transmit its packets. A value between 0 and m can be specified. Determination of m is project
dependent.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the traffic scheduling on CoS queue 1, with a weight value of 15, on port 1:10:
DGS-3627:admin# config scheduling ports 1:10 1 max_packet 15
Command: config scheduling ports 1:10 1 max_packet 15
Success.
DGS-3627:admin#
config scheduling_mechanism
Purpose
Used to configure the traffic scheduling mechanism for each CoS queue.
Syntax

config scheduling_mechanism
Description
There are two sets of commands that the project can be choose to implement.
If the project only supports the scheduling mechanism to be set globally, the portlist
parameter will not be supported.
This command is used to specify how the switch handles packets in priority queues.
Parameters
ports <portlist>
- Specifies a range of ports to be configured.
all
- To set all ports in the system, you may use the “all” parameter. If no parameter is
specified, the system will set all ports.
strict
- All queues will operate in strict mode.
weight_fair
- Each queue will operate based on their settings.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the traffic scheduling mechanism for the CoS queue on port 1:1:
DGS-3627:admin# config scheduling_mechanism ports 1:1 strict
Command: config scheduling_mechanism ports 1:1 strict
Success.
DGS-3627:admin#
show scheduling
Purpose
Used to display the current traffic scheduling parameters.
Syntax
show scheduling {<portlist>}
Description
The show scheduling command displays the current traffic scheduling parameters in use on
the Switch.
Parameters
portlist
- Specifies the range of ports to be displayed.
If portlist is not specified, for the projects that support the per-port scheduling configure,
system will display all ports’ scheduling configurations, for those projects that only support
the global scheduling settings, this command will display the global setting only.
Restrictions
None.
Example usage:
To display the traffic scheduling parameters for each CoS queue on port 1:1 (take eight hardware priority queues for
example):

show scheduling_mechanism
Purpose
Used to show the traffic scheduling mechanism.
Syntax
show scheduling_mechanism { <portlist> }
Description
The show scheduling_mechanism command displays the traffic scheduling mechanism.
Parameters
portlist
- Specifies a range of ports to be displayed.
If no portlist is specified, for the projects that support the per-port scheduling mechanism
configure, system will display all ports’ scheduling mechanism configurations, for those
projects that only support the global scheduling mechanism settings, this command will
display the global setting only.
Restrictions
None.
Example usage:
To show the scheduling mechanism for all ports:

config 802.1p user_priority
Purpose
Used to map the 802.1p user priority of an incoming packet to one of the eight hardware
queues available on the Switch.
Syntax
config 802.1p user_priority { ports [<portlist> | all ]} <priority 0-7> <class_id 0-6>
Description
The config 802.1p user_priority command is used when you want to configure the way that
the switch will map an incoming packet, based on its 802.1p user priority, to one of the
available hardware priority queues on the switch.
Parameters
ports <portlist>
- Specifies the range of ports to be configured.
all
- To set all ports in the system, you may use the “all” parameter. If no parameter is
specified, the system will set all ports.
priority
- The 802.1p user priority you want to associate the <class_id> (the number of the
hardware queue) with.

config 802.1p user_priority
class_id
- The number of the switch’s hardware priority queue. The switch has 7 hardware
priority queues available. They are numbered between 0 (the lowest priority) and 6 (the
highest priority).
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure an 802.1p user priority of 1 and a class_ID of 3 on port 1:1:
DGS-3627:admin#
config 802.1p user_priority ports 1:1 1 3
Command: config 802.1p user_priority ports 1:1 1 3
Success.
DGS-3627:admin#
show 802.1p user_priority
Purpose
Used to display the 802.1p user priority.
Syntax
show 802.1p user_priority {<portlist>}
Description
The show 802.1p user_priority command displays 802.1p user priority for ports.
Parameters
portlist
- Specifies the range of ports to be displayed.
If no portlist is specified, this command will display the 802.1p user priority for all ports.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
In the case of Project only support global configuration, display the 802.1p user priority:
DGS-3627:admin#show 802.1p user_priority 1:1

config 802.1p default_priority
Purpose
Used to configure the 802.1p default priority settings on the Switch. If an untagged packet is
received by the Switch, the priority configured with this command will be written to the
packet’s priority field.
Syntax
config 802.1p default_priority [ <portlist> | all ] <priority 0-7>
Description
The configure 802.1p default_priority command allows you to specify default priority handling
of untagged packets received by the Switch. The priority value entered with this command

config 802.1p default_priority
will be used to determine the hardware priority queues that the packet will be forwarded to.
Parameters
portlist
- This specifies the range of ports, which require the default priority settings
configured on. That is, the range of ports which receive all untagged packets will be assigned
the priority specified below. 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.
all
- Specifies that the command will apply to all ports on the switch.
priority
- The priority value (0 to 7) assigned to untagged packets received by the switch or a
range of ports on the switch.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure an 802.1p default priority settings of 5 on all Switch ports:
DGS-3627:admin# config 802.1p default_priority all 5
Command: config 802.1p default_priority all 5
Success.
DGS-3627:admin#
show 802.1p default_priority
Purpose
Used to display the current default priority settings on the Switch.
Syntax
show 802.1p default_priority { <portlist> }
Description
The command displays the current configured default priority settings on the switch.
The default priority can also be assigned by the RADIUS server through the authentication
process. Authentication with the RADIUS server can be either per port or per user. For per
port authentication, the priority assigned by the RADIUS server will be the default priority of
the effective port. For per user authentication, the priority assigned by RADIUS will not be the
effective port default priority, as the will priority associated with MAC address will be
assigned. Note that only devices supporting MAC-based VLANs can provide per user
authentication.
Parameters
portlist
- Specifies the range of ports to be displayed.
If no parameter is specified, all ports with an 802.1p default priority will be displayed.
Restrictions
None.
Example usage:
To display the 802.1p default priority on ports 1:1-1:10:
