Hello Jong,

have a look at the following document

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/12-2/15-02SG/configuration/guide/config/secure.html#88478

The command should be:

access-list hardware region feature + other parameters

in global config

Hope to help

Giuseppe

Thank you, Giuseppe.

I try to input 'access-list hardware region feature + other parameters' in global config
but there's no command 'ccess-list hardware region'.

web_4948E(config)#access-list hardware ?
capture Determine how to capture certain control packets

web_4948E(config)#access-list hardware

Can i allocate from Output Unallocated 20480 to Output Security, directly. (2048 or 1024, or 4096, not balance)

Hello Jong,

a more recent configuration guide is here

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/XE3-8-0E/15-24E/configuration/guide/xe-380-configuration/secure.html#47441

However, I cannot find the new commands for TCAM sizing.

I am searching in it.

The command that you have found can be used only for troubleshooting by performing capture of packets sent to the main cpu. It is a different feature.

Hope to help

Giuseppe
