The following are the new software features introduced in Cisco ASR 1000 Series Aggregation Services Routers Release 3.13.0S:
ISM Restartability
When the ISM-VPN module is disabled because of a crash, the router’s encryption and decryption performance degrade due to the usage of an on board crypto-engine. The ISM Restartability feature allows you to reboot the module so that the ISM-VPN module can register again as a new crypto engine and download the relevant policies required to handle the crypto load of the router.
The ISM Module can be rebooted 3 times in an hour. However, if there are more than three crashes in less than an hour, the ISM-VPN module is not rebooted. You must reset the timers and enable the ISM-VPN module using the crypto engine slot and crypto engine accelerator command.
Zone-based Firewall Per-filiter Statistics
The output of the show policy-map type inspect zone-pair has been modified to display filter statistics.
Important Notes

End-of-Sale and End-of-Life of the Cisco Traditional NetFlow Feature
Cisco announces the end-of-sale and end-of-life of the Cisco Traditional NetFlow (TNF) Feature on the Cisco ASR1000 platform. Cisco will not have any future development, CLI support, TAC support, and documentation pertaining to the Cisco TNF feature beyond Cisco IOS XE Software Release 3.10.
Customers with the Cisco TNF feature on the Cisco ASR1000 platform are encouraged to migrate to the Cisco Flexible NetFlow (FNF) feature on the Cisco ASR1000 platform.
For details on transition to Cisco FNF, see the Migrating from Traditional to Flexible NetFlow white paper:

Important Notes About Cisco ASR 1000 Series Aggregation Services Routers Release 3.13S
Important notes specific to Cisco ASR 1000 Series Aggregation Services Routers Release 3.13S are as follows:
IP SLA HTTP Operation
Prior to this release, if a remote server replies back to HTTP request, the status of an IP SLA HTTP probe would be up, regardless of the HTTP errors, such as 400 (bad request), 404 (not found), 500 internal server error), etc. IP SLA probe goes down when a probe is unable to establish a TCP connection or unable to receive an answer from the remote server to the HTTP request.
Effective with this release, error codes determine the behavior of IP SLA HTTP probe, which goes down when the return code is not 200 (OK).
