New Software Features in Cisco IOS XE Release 3.9(0)S
Release 3.9(0) introduces support for the following software features:
- BFD Echo Mode Hardware Offloading—BFD echo mode detects forwarding path failures on the remote system using echo packets; this release introduces support for hardware offloading of BFD echo mode packets for up to 255 sessions. The minimum supported timer value for offloaded BFD echo mode sessions is 3.3 ms. BFD echo offloading directs BFD echo packets to the high priority queue instead of the default queue. For more information about how to configure BFD, see
– IP Routing: BFD Configuration Guide, Cisco IOS XE Release 3S (Cisco ASR 900).
- BGP Support for 4-byte ASN —This release introduces support for 4-byte autonomous system numbers in both the asplain format and the asdot format as described in RFC 5396. For more information, see
– http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_bgp/configuration/xe-3s/asr903/irg-4byte-asn.html
- CFM Support for Trunk EFP—This release introduces support for CFM on trunk EFP interfaces. For more information about configuring EFPs, see

- Enhanced Object Tracking—The Enhanced Object Tracking feature separates the tracking mechanism from Hot Standby Router Protocol (HSRP) in order to create a separate standalone tracking process. The tracking process is available to other IOS processes and allows tracking of other objects in addition to the interface line-protocol state. For more information, see
– http://www.cisco.com/en/US/docs/ios/ios_xe/ipapp/configuration/guide/ipapp_eot_xe.html.
- Embedded Event Manager (EEM) 4.0—Embedded Event Manager (EEM) is a distributed and customized approach to event detection and recovery offered directly in a Cisco IOS device. EEM offers the ability to monitor events and take informational, corrective, or any desired EEM action when the monitored events occur or when a threshold is reached. For more information, see
– http://www.cisco.com/en/US/docs/ios-xml/ios/eem/configuration/xe-3s/eem-overview.html.
