Troubleshooting SDM Problems
The enhanced Gigabit Ethernet interface module is available with 32 KB, 64 KB, or 256 KB TCAM
space. You can configure the various protocol regions in TCAM based on your requirements and on the
size of TCAM on your Gigabit Ethernet interface module.
Figure 11-23 Dynamic CAM and TCAM Relationship
Note The enhanced Gigabit Ethernet interface module is available with 32 KB, 64 KB, or
256 KB TCAM space. The maximum SDM size is equal to the lowest TCAM size available among
the interface modules present at the time of booting up the switch router. For example, if you have
two interface modules with 64 KB and 256 KB TCAM sizes, then the maximum SDM size is 64 KB
based on the lowest TCAM size available at bootup.

Displays the SDM management
information for each protocol region in
TCAM
sdm size region-name {num-entries | k-entries
num-k-entries}
Sets the name of the protocol region for
which you want to configure the size.
sdm access-list num-entries Sets the name of the protocol region for
