An NSE-150 has 2 GB of DRAM. NSE-100 RAM is user-configurable using an SDRAM SODIMM. While most NSE-100s have 512 MB of RAM, 256-MB and 128-MB SDRAM SODIMMs for the NSE-100 exist.
On a Cisco 7304 router using an NSE-150, the default memory limit for Turbo ACL processes (such as classification, compilation, and table storage) of Layer 3 and Layer 4 data in the RP path is always 256 MB. The default memory limit for Turbo ACL processes for Layer 2 data in the RP path for a Cisco 7304 router using an NSE-150 is always 128 MB.
On a Cisco 7304 router using an NSE-100, the default amount of memory reserved for Turbo ACL processes in the RP path is dependant upon the amount of SDRAM configured on the NSE-100. If the NSE has 512 MB of SDRAM or more, the default memory limit for Turbo ACL processes for Layer 3 and Layer 4 traffic processing is 256 MB. If the processor has less than 512 MB of SDRAM, the default memory limit for Turbo ACL processes for Layer 3 and Layer 4 traffic is 128 MB.
The default amount of memory reserved for Layer 2 Turbo ACL processes for a Cisco 7304 router using an NSE-100 is always 128 MB, regardless of the amount of memory configured on the processor.
To see the default amount of memory reserved for Layer 2 or for Layer 3 and Layer 4 Turbo ACL processing on your Cisco 7304 router, enter the
show
access-list
compiled command. The “Mb default limit” output, which appears in both the “Compiled ACL statistics for IPv4” and “Compiled ACL statistics for Data-Link” sections of the output, shows you the default memory reservations for either Layer 2 or Layer 3 and Layer 4 Turbo ACL processing. See "Monitoring Turbo ACL Memory Usage in the Route Processing Path" for a more detailed explanation of this procedure.
To change the default amount of memory reserved for Layer 2 or Layer 3 and Layer 4 Turbo ACL processing on your Cisco 7304 router, enter the
