IPv6 IPSec QoS (LLQ and QoS Pre-Classify)

The IPv6 IPSec QoS feature applies the Quality of Service (QoS) policies to IPV6 IPsec. This feature supports the following functionalities:

  • Crypto LLQ QoS: Traffic that is classified as priority, for example PAK priority, is en-queued to the priority queue before the crypto processor. The Low Latency Queuing (LLQ) for IPSec encryption engines helps reduce packet latency for priority traffic.
  • IPSec QoS pre-classify: QoS pre-classify is configured under a crypto map to enable IPSec to save the original Layer 3 and Layer 4 header before the encryption so that Quality of Service (QoS) can do the classification using the saved header.
  • QoS group-based LLQ: The QoS group-based LLQ feature allows IPSec to check the LLQ QoS group setting to determine whether a packet is a high priority packet before it is en-queued to Low Latency Queue (LLQ).

The following commands were modified: crypto map and qos pre-classify to reflect IPv6 capabilities

ISDN Phase 2 (for LAC) on E1

For detailed information, see the following Cisco document:

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/vpdn/configuration/xe-3s/vpd-xe-3s-book/vpd-isdn-access-bba.html

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/IWAG_Config_Guide_BookMap.html

http://www.cisco.com/en/US/docs/ios-xml/ios/interface/configuration/xe-3s/ir-mpls-vpnomgre-xe.html

Multi-Topology BGP with VRF enhancement

The Multi-Topology BGP with VRF enhancement feature enables multi- topology BGP routing in VRF. There are no new BGP commands introduced or modified for this feature. If multi-topology BGP is configured, the "address-family (ipv4 | ipv6) multicast" command under a specific "vrf definition" is used for configuration; else all multicast VRF activity is configured using the "address-family (ipv4 | ipv6)" command under "vrf definition".

Multicast MT mode in VRF

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/ios-xml/ios/ipmulti_pim/configuration/xe-3s/imc_pim_multicast_vrf.html

NBAR2: Add/rename static attributes

The custom values enable you to name the attributes based on grouping of protocols. You can create custom values for the application-group, category, and sub-category attributes. Use the ip nbar attribute application-group custom application-group-name, ip nbar attribute category custom category-name, and ip nbar attribute sub-category custom sub-category-name to add custom values for the attributes application-group, category, and sub-category, respectively.

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/ios-xml/ios/qos_nbar/configuration/xe-3s/asr1000/clsfy-traffic-nbar.html

NBAR2: GETVPN (Crypto-Map) Support

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/ios-xml/ios/qos_nbar/configuration/xe-3s/asr1000/clsfy-traffic-nbar.html

NBAR2 Integrated Protocol Pack 6.0.0

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/ios-xml/ios/qos_nbar/prot_lib/config_library/pp600/nbar-prot-pack600.html

NBAR2: Integrate NBAR Taxonomy into the router

The NBAR taxonomy file contains the information such as common name, description, underlying protocol, for every protocol that is available in the protocol pack. Use the show ip nbar protocol-pack active taxonomy, show ip nbar protocol-pack inactive taxonomy, and show ip nbar protocol-pack loaded taxonomy commands to view the taxonomy for an active, inactive, and all loaded protocol packs, respectively.

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/ios-xml/ios/qos_nbar/configuration/xe-3s/asr1000/nbar-protocl-pack.html

Observation Point ID - distinguish metrics from different interfaces

The Observation Point ID metric identifies a monitored interface for traffic in both directions (ingress and egress). A single flow definition using this metric can be used in place of match interface input and match interface output, making configuration more compact and enabling a single record collected on an interface to include metrics for traffic in both directions.

For detailed information, see the following Cisco document:

http://www.cisco.com/en/US/docs/ios-xml/ios/sec_conn_dmvpn/configuration/xe-3s/sec-conn-dmvpn-per-tunnel-qos.html

Pv6 IPSec QoS (LLQ and QoS Pre-Classify)

The IPv6 IPSec QoS feature applies the Quality of Service (QoS)policies to IPV6 IPsec. This feature supports the following functionalities:

  • Crypto LLQ QoS: Traffic that is classified as priority, for example PAK priority, is en-queued to the priority queue before the crypto processor. The Low Latency Queuing (LLQ) for IPSec encryption engines helps reduce packet latency for priority traffic.
  • IPSec QoS pre-classify: QoS pre-classify is configured under a crypto map to enable IPSec to save the original Layer 3 and Layer 4 header before the encryption so that Quality of Service (QoS) can do the classification using the saved header.
  • QoS group-based LLQ: The QoS group-based LLQ feature allows IPSec to check the LLQ QoS group setting to determine whether a packet is a high priority packet before it is en-queued to Low Latency Queue (LLQ).

The following commands were modified: crypto map and qos pre-classify to reflect IPv6 capabilities

Retain DSCP setting of RTP packet

This feature introduces the preserving and forwarding of Differentiated services code point (DSCP) markings received from endpoints by Cisco Unified Communications Manager (CUCM) when the programmed value from CUCM is NULL. Media Termination Point (MTP) does not store the DSCP for a session, but picks the value from an incoming packet and inserts it into an outgoing packet. Thus DSCP value from an endpoint can change in the middle of a session.

RSVP Over UDP

For detailed information, see the following Cisco document:

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipapp/configuration/xe-3s/iap-xe-3s-book/iap-tcp.html

VRF aware BGP translate-update

The VRF aware BGP translate-update feature enables customer devices, that contain an old version of Cisco software that does not support multicast BGP routing, to advertise its routes to multicast VRF- Lite, multicast VPN for VPNv4 and VPNv6 neighbors, as well as through IPv6 over IPv4 tunnel. The "neighbor" command is modified to include the "translate-update" keyword that enables this feature and applies only to the VRF address families.

Weighted Fair Queueing, High Priority Policer and Configurable threshold for Pause Framesfeature for 40G Native Ethernet Line card on ASR1000

For detailed information, see the following Cisco document:
