Data buffer commands
Basic data buffer commands
Inappropriate data buffer changes can cause system problems. Before manually changing data buffer settings, make sure you understand its impact on your device. As a best practice, use the burst-mode enable command if the system requires large buffer spaces. The burst-mode enable command and the buffer apply command are mutually exclusive. If you have configured the data buffer by using one command, you must execute the undo form of the command before using the other command.
buffer apply
Use buffer apply to apply manually configured data buffer settings.
Use undo buffer apply to restore the default.
Syntax
buffer apply
undo buffer apply

Predefined user roles
network-admin
Usage guidelines
For data buffer settings to take effect, you must execute this command after configuring data buffer settings.
After applying manually configured data buffer settings, you cannot directly modify the applied settings. To modify them, you must cancel the application, reconfigure data buffer settings, and reapply the new settings.
On an S6820 switch, this command might cause the PFC function to be on longer in effect or to operate incorrectly. For information about PFC configuration commands, see Ethernet interface commands in Layer 2—LAN Switching Command Reference.
Examples
# Apply manually configured data buffer settings.
<Sysname> system-view
[Sysname] buffer apply
buffer packet-drop alarm enable
Use buffer packet-drop alarm enable to enable packet-drop alarms.
Use undo buffer packet-drop alarm enable to disable packet-drop alarms.

Default

Predefined user roles
network-admin
Usage guidelines
The device generates and reports packet-drop alarms to a network management system (such as IMC) for displaying the data buffer usage.
This command does not take effect only on the Headroom buffer.
Examples
# Enable packet-drop alarms.
<Sysname> system-view
[Sysname] buffer packet-drop alarm enable

buffer packet-drop alarm interval
buffer packet-drop alarm interval
Use buffer packet-drop alarm interval to set the interval for sending packet-drop alarms.
Use undo buffer packet-drop alarm interval to restore the default.
|

Parameters
interval: Specifies the interval for sending packet-drop alarms, in the range of 0 to 60 seconds. The value of 0 indicates that packet-drop alarms are sent immediately after they are generated.
Usage guidelines
This command takes effect only when packet-drop alarms are enabled.
Examples
# Set the interval for sending packet-drop alarms to 20 seconds.
<Sysname> system-view
[Sysname] buffer packet-drop alarm interval 20

buffer queue guaranteed
Use buffer queue guaranteed to set the fixed-area space for a queue.
Use undo buffer queue guaranteed to delete the fixed-area space setting of a queue.
Syntax
buffer egress [ slot slot-number ] cell queue queue-id guaranteed ratio ratio
undo buffer egress [ slot slot-number ] cell queue queue-id guaranteed
Default
The fixed-area ratio for a queue is 13%.

network-admin
Parameters
egress: Specifies the egress buffer.
slot slot-number: Specifies an IRF member device by its member ID (slot number). If you do not specify an IRF member device, this command applies to all IRF member devices.
cell: Specifies cell resources.
queue-id: Specifies a queue by its ID in the range of 0 to 7.
ratio ratio: Specifies the fixed-area space ratio, in percentage. The value range for ratio is 1 to 100.
Usage guidelines
By default, all queues have an equal share of the fixed area. You can set the fixed-area ratio for a queue. The other queues equally share the remaining part.
The fixed-area space for a queue cannot be used by other queues. Therefore, it is also called the minimum guaranteed buffer for the queue. The sum of fixed-area space configured for all queues cannot exceed the total fixed-area space. Otherwise, the configuration fails.
Examples
# Configure queue 0 to use 20% fixed-area space of cell resources in the egress buffer.
<Sysname> system-view
[Sysname] buffer egress cell queue 0 guaranteed ratio 20
buffer queue shared
Use buffer queue shared to set the maximum shared-area ratio for a queue.
Use undo buffer queue shared to delete the maximum shared-area ratio setting of a queue.
Syntax
buffer egress [ slot slot-number ] cell queue queue-id shared ratio ratio
undo buffer egress [ slot slot-number ] cell queue queue-id shared
Default
The maximum shared-area ratio for a queue is 88%.

Parameters
egress: Specifies the egress buffer.
slot slot-number: Specifies an IRF member device by its member ID (slot number). If you do not specify an IRF member device, this command applies to all IRF member devices.
cell: Specifies cell resources.
queue-id: Specifies a queue by its ID in the range of 0 to 7. If you do not specify a queue, this command sets the maximum shared-area space for each port.
ratio ratio: Specifies the maximum shared-area space ratio, in percentage. The value range for ratio is 0 to 100.
Usage guidelines
By default, all queues have an equal share of the shared area. You can set the shared-area ratio for a queue. The unconfigured queues use the default setting. The shared-area space for each queue is finally determined by the chip based on your configuration and the number of packets to be received and sent.
Examples
# Configure queue 0 to use up to 10% shared-area space of cell resources in the egress buffer.
<Sysname> system-view
[Sysname] buffer egress cell queue 0 shared ratio 10

network-admin
Usage guidelines
The Burst feature is especially useful for reducing packet losses under the following circumstances:
· Broadcast or multicast traffic is intensive, resulting in bursts of traffic.
· Traffic enters a device from a high-speed interface and goes out of a low-speed interface.
· Traffic enters a device from multiple same-rate interfaces and goes out of an interface with the same rate.
On an S6820 switch, disabling the Burst feature after enabling it might cause the PFC function to be on longer in effect or to operate incorrectly. For information about PFC configuration commands, see Ethernet interface commands in Layer 2—LAN Switching Command Reference.
Examples
# Enable the Burst feature.
<Sysname> system-view
[Sysname] burst-mode enable

Usage guidelines
The Fabric Monitor and Analyzer (FMA) feature works with IMC to perform device monitoring and analysis. The switch acts as an FMA agent, and the IMC server acts as an FMA client. The FMA-related commands do not take effect after you configure them on the FMA agent. You must configure the following settings on the FMA client:
· Agent's IP address, MAC address, and port number.
· Client's IP address and port number.
After you configure these settings and enable the Microburst feature on the FMA client, the FMA agent automatically receives these settings from the FMA client.
After the FMA agent receives these settings, it can exchange device monitoring and analysis information with the FMA client.
In the current software version, this feature supports only data buffer statistics and detection. Data buffer statistics are buffer usage statistics for queues. Data buffer detection information is the buffer usage threshold for queues.
