GWCON Process

To display the current logging level, do not enter an octal number as part of the command. To change the logging level, enter the octal number of the new logging level as part of the command. The default logging level is 76 (octal).

Note: To change the initial logging level (that is, the level that the router uses when it starts), use the CONFIG set logging level command. (Refer to ªChapter 5. The Con®guration Process (CONFIG - Talk 6) and Commandsº on page 39 for information about this command.)

Syntax:

log [octal_#]

Memory

Use the memory command to display the current CPU memory usage in bytes, the number of buffers, and the packet sizes.

To use this command, free memory must be available. The number of free packet buffers may drop to zero, resulting in the loss of some incoming packets; however, this does not adversely affect router operations. The number of free buffers should remain constant when the router is idle. If it does not, contact your service representative.

Syntax: memory

Example:

memory
Physical installed memory:			16 MB
Total routing (heap) memory:			12 MB
Routing memory in use:			13 %
	Total	Reserve	Never	Perm	Temp	Prev
			Alloc	Alloc	Alloc	Alloc
Heap memory	12231155	26488 10687312		1438487	104924	432
Number of global buffers: Total = 300, Free = 300, Fair = 77, Low = 60
Global buff size: Data = 2048, Hdr = 17, Wrap = 72, Trail = 65, Total = 2208
Physical installed memory
The total amount of physical RAM installed in the router.
Total routing memory
The amount of memory available to the routing function, not including that
allocated to the base operating system, system extensions, or options such
as APPN. This is also called ²heap² memory, and matches the ²Total² heap
memory size given in bytes shortly thereafter.
Routing memory in use
The percentage of total routing memory that is currently being used by the
routing function. Heap memory currently in use is counted under the
following headings Perm Alloc and Temp Alloc.

Heap memory:

Amount of memory used to dynamically allocate data structures.

Total Total amount of space available for allocation for memory.
