Viewing MPX Memory Statistics
The
memstat
command displays the
MPX’s
memory statistics. The statistics will tell you how
memory is currently being used and help determine if memory problems exist, such as
memory exhaustion. To view the
MPX’s
memory statistics, enter
memstat
at the system prompt. A screen similar to the following will be displayed.

The fields displayed by the
memstat
command are described below.
status
. The statistics appear in two groups:
current
and
cumulative
. The current status shows
free and allocated memory. The cumulative status shows only allocated memory. Cumulative
memory is the total amount of memory that has been allocated since the switch was started
up. This value increases each time a memory allocation takes place. It can never decrease.
bytes
. The number of bytes for free and allocated memory.
blocks
. Block size is dynamic and depends upon memory usage and the amount of fragmen-
tation.
avg block
. The average block indicates the average size of all the memory blocks.
max block
. The maximum block indicates the largest free memory block available. When this
value drops to around 10K it usually indicates that the free memory is highly fragmented and
probably near exhaustion.
MPM total memory
. The total number of megabytes available in the
MPX’s
memory.
