Displaying Memory Information

Use the Memory window to view information about the line card's CPU memory, number of buffers, and packet sizes. This information reflects activity occurring on the line card's management processor only. It does not include data about memory in the line card's forwarding subsystem.

To display information about Buffer Sizes, use the CLI.

 

Field Descriptions

Permanently Amount of memory requested for permanent allocation.
Temporarily Amount of memory temporarily allocated.
Never Allocated Amount of memory that has never been allocated.

Buffer Memory
Total Global Buffers Original number of global buffers on the system.
Free Global Buffers Current number of global buffers available.
Buffer Water Marks
Fair Share Fair number of buffers for each interface.
Low Number of free buffers at which the allocation strategy changes to conserve buffers. If the value is less than Low, then buffers are not placed on any queue containing more than the Fair Share number of buffers.
