[Quidway] memory auto-establish enable
5.1.5 memory safety | limit
Syntax
memory { safety safety-value | limit limit-value }*
undo memory [ safety | limit ]
View
System view
Parameter
safety-value: Safety free memory of the switch , in Mbytes. Its value range depends on
the free memory of the current switch. This value defaults to 5.
limit-value: Lower limit of the switch free memory, in Mbytes. Its value range depends
on the free memory of the current switch. This value defaults to 4.
Description
Use the memory limit limit-value command to configure the lower limit of the switch
free memory.
When the free memory of the switch is less than this limit, all the routing protocol
connections will be disconnected forcibly. The limit-value argument in the command
must be less than the current free memory safety value; otherwise, the configuration
will fail.
Use the memory safety safety-value command to configure the safety value of the
switch free memory.
If you use the memory auto-establish enable command (the default configuration),
the routing protocol connection that is forcibly disconnected automatically recovers
when the free memory of the switch reaches this value. The safety-value argument in
the command must be greater than the current free memory lower limit; otherwise, the
configuration will fail.
Use the memory safety safety-value limit limit-value command to change both the
safety value and lower limit of the switch free memory. The value of safety-value must
be greater than that of limit-value; otherwise, the configuration will fail.
