New Software Features in Cisco IOS XE Release 3.12S
IP SLAs TWAMP Responder
The IETF Two-Way Active Measurement Protocol (TWAMP) defines a standard for measuring
round-trip network performance between any two devices that support the TWAMP protocols. The
TWAMP-Control protocol is used to set up performance measurement sessions. The TWAMP-Test
protocol is used to send and receive performance-measurement probes.
For more information, see
Network Time Protocol (NTP) Timestamping
Starting with Cisco IOS XE Release 3.12S, additional NTP Time of Day synchronization configuration
is supported when NTP is chosen for time synchronization for one-way delay or delay-variation
measurements on source and destination devices.
For more information, see
Auto-IP for SVI, Port Channel and VRF
The Auto-IP feature addresses the problem of manually reconfiguring nodes during insertion, deletion,
and movement of nodes within an auto-IP ring. The auto-IP feature automatically provides IP addresses
to the node interfaces inserted into an auto-IP ring.
For more information, see Auto-IP.
Autonomic Networking
Autonomic networking makes network devices intelligent by introducing self-management concepts that
simplify network management for the network operator.
For more information, see
BGP Accumulated IGP
The BGP Accumulated IGP feature is an optional nontransitive Border Gateway Protocol (BGP) path
attribute.The attribute type code for the accumulated interior gateway protocol (AIGP) attribute is
assigned by the Internet Assigned Numbers Authority (IANA). The value field of the AIGP attribute is
defined as a set of type, length, value (TLV) elements. The AIGP TLV contains the AIGP metric.
