This counter will increment when the appliance receives an IPSec ESP packet, IPSec NAT-T ESP packet or an IPSec over UDP ESP packet encapsulated in an IP version 6 header. If you are receiving many IPSec not AH or ESP indications on your appliance, analyze your network traffic to determine the source of the traffic. This counter will increment when the appliance receives a packet on an IPSec connection which is not an AH or ESP protocol. If IPSec over UDP is not configured on your appliance, analyze your network traffic to determine the source of the IPSec over UDP traffic. If you have configured IPSec over UDP on your appliance, this indication is normal and doesn't indicate a problem. Note - These are not industry standard NAT-T keepalive messages which are also carried over UDP and addressed to UDP port 4500. IPSec over UDP keepalive messages are sent from the IPSec peer to the appliance to keep NAT/PAT flow information current in network devices between the IPSec over UDP peer and the appliance. This counter will increment when the appliance receives an IPSec over UDP keepalive message. If NAT-T is not configured on your appliance, analyze your network traffic to determine the source of the NAT-T traffic. If you have configured IPSec NAT-T on your appliance, this indication is normal and doesn't indicate a problem.

NAT-T keepalive messages are sent from the IPSec peer to the appliance to keep NAT/PAT flow information current in network devices between the NAT-T IPSec peer and the appliance. This counter will increment when the appliance receives an IPSec NAT-T keepalive message. The following sections include each drop reason name and description, including recommendations: Is used for debugging purposes only, and the information output is subject to change. See the general operations configuration guide for more information about the accelerated security path. The show asp drop command shows the packets or connections dropped by the accelerated security path, which might help you troubleshoot a problem. It also displays the drop reason keywords next to the description, so you can easily use the capture asp-drop command with the associated keyword. Output includes a timestamp indicating when the counters were last cleared (see the clear asp drop command). The following table shows the modes in which you can enter the command: Use ? to see a list of possible frame drop reasons. You can specify a particular reason by using the frame_drop_reason argument. Use ? to see a list of possible flow drop reasons. You can specify a particular reason by using the flow_drop_reason argument. (Optional) Shows the dropped flows (connections).

Show asp drop | frame ] Syntax Description In this case, the reduction in image quality can vary from insignificant to substantial.To debug the accelerated security path dropped packets or connections, use the show asp drop command in privileged EXEC mode. The file compression ratio is in the range from 10:1 to 100:1.

The format acts simultaneously as the standard of ISO and the International Telecommunication Union. JPEG uses a 'lossy' compression system and discrete cosine transform technology. Finally, the colors and brightness are coded. First, the photo is transformed into a color space YCbCr, and then it is divided into squares to determine the upper range of the color spectrum. The procedure for compressing the digital images in JPG format is carried out in several stages. A strong contrast between several near located pixels provokes the appearance of visible artifacts. It is not recommended to use this format for compression of drawings and various kinds of graphics. The JPG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present. It is also frequently used in memory cards of digital video cameras. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It uses the technology of encoding smooth color renditions, providing the ability to frequently reduce the amount of data during the image's recording. JPG – is a popular graphic format characterized by a high image compression rate, which leads to a decrease in image quality.
