For IPS standalone appliances with 1 G and 10 G fixed or add-on interfaces, the maximum jumbo frame 
size is 9216 bytes. For integrated IPS sensors, such as the ASA 5500-X and ASA 5585-X series, refer to

A jumbo frame is an Ethernet packet that is larger than the standard maximum of 1518 bytes (including 
Layer 2 header and FCS).

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. 
This miscount is a result of header bytes added to the packet by the ASA before the packet is transmitted 
to the IPS. For IPv4, 58 bytes of header data are added. For IPv6, 78 bytes of header data are added. The 
ASA removes the added IPS header before the packet leaves the ASA.

You can find major and minor updates, service packs, signature and signature engine updates, system 
and recovery files, firmware upgrades, and Readmes on the Download Software site on Cisco.com. 
Signature updates are posted to Cisco.com approximately every week, more often if needed. Service 
packs are posted to Cisco.com in a release train format, a new release every three months. Major and 
minor updates are also posted periodically. Check Cisco.com regularly for the latest IPS software.
