Viewing CAM Information
The
camstat
command displays information and usage about the content addressable memory
(
CAM
) on each switching module in the chassis. To view this
CAM
information, enter
camstat
at the system prompt. Something similar to the following will be displayed.
Slot # of CAMs Cfg Usage Max Avail Actual Usage
------ --------------- ---------------------- --------------------- -----------------------
MPM 1 NA NA NA
2 4 (2 + 2) 0 3966 0
3 1 (1 + 0) 0 1008 0
4 1 (1 + 0) 0 1004 0
5 4 (2 + 2) 0 4093 0
The fields displayed by the
camstat
command are described below.
Slot
. The slot number of the switching module for which
CAM
information is provided.
# of CAMs
. The number of
CAM
chips installed on the switching module.
Cfg Usage
. The number of
CAM
entries this module is configured to support. By default a
module will use the maximum amount of entries supported by on-board
CAM
. However, you
can alter this default through the
camcfg
command (described in Configuring CAM Distribu-
tion on page 9-25) to make the most efficient use of the
CAM
distributed among all switching
modules in the chassis. Up to 31.25 K of
CAM
is supported over all modules in an Omni
Switch/Router.
Max Avail
. The number of
CAM
entries available. This number will be less than the number of
CAM
entries configured because some entries will be used by learned
MAC
addresses (shown
in the
Actual Usage
column) and others are used internally by the OmniSwitch.
Actual Usage
. The number of
MAC
addresses learned by the module in this slot.

For
CAM
statistics for an entire chassis, use the

Statistics.”
