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
Views
System view
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.
Examples
# Apply manually configured data buffer settings.
<Sysname> system-view
[Sysname] buffer apply
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 | packet } queue queue-id
guaranteed ratio ratio
undo buffer egress [ slot slot-number ] { cell | packet } queue queue-id
guaranteed
Default
The cell resource ratio for a queue is 12% of the total cell resources. The packet resource ratio for a
queue is 12% of the total packet resources.
