Procedure
Step 1
Step 2
Step 3
Step 4
Step 5
The following example shows how to change the size of the RACL TCAM region:
switch(config)# hardware access-list tcam region racl 256
[SUCCESS] New tcam size will be applicable only at boot time.
You need to 'copy run start' and 'reload'
switch(config)# copy running-config startup-config
switch(config)# reload
WARNING: This command will reboot the system
Do you want to continue? (y/n) [n] y
This example shows how to display the TCAM region sizes to verify your changes:
switch(config)# show hardware accesslist tcam region | exclude "0"

• tcam_size—TCAM size. The range is from 0 to
2,14,74, 83, 647 entries.
Saves the change persistently through reboots and restarts
by copying the running configuration to the startup
configuration.
Displays the TCAM sizes that will be applicable on the
