The ASA 5500-X IPS SSP and Memory Usage

For the ASA 5500-X IPS SSP, the memory usage is 93%. The default health thresholds for the sensor are 80% for yellow and 91% for red, so the sensor health will be shown as red on these platforms even for normal operating conditions. You can tune the threshold percentage for memory usage so that it reads more accurately for these platforms by configuring the memory-usage-policyoption in the sensor health metrics.

Note Make sure you have the memory-usage-policyoption in the sensor health metrics enabled.

Table C-3lists the yellow-threshold and the red-threshold health values.

Platform		Yellow	Red	Memory Used
ASA 5512-X IPS SSP		85%	91%	28%
ASA 5515-X IPS SSP		88%	92%	14%
ASA 5525-X IPS SSP		88%	92%	14%
ASA 5545-X IPS SSP		93%	96%	13%
ASA 5555-X IPS SSP		95%	98%	17%

The ASA 5500-X IPS SSP and Jumbo Packets

	The jumbo packet count in the show interface command output from the lines Total Jumbo Packets
	Received and Total Jumbo Packets Transmitted for ASA IPS modules may be larger than expected
	due to some packets that were almost jumbo size on the wire being counted as jumbo size by the IPS.
