The Access Pseudowire Redundancy feature allows you to configure a backup pseudowire under the bridge domain. When the primary pseudowire fails, the provider edge (PE) router switches to the backup pseudowire. The primary pseudowire resumes operation after it becomes functional. The primary pseudowire fails when the PE router fails or when there is a network outage.

See NCS 560 Content Link.

The Cisco IOS XR 7.1.2 Release introduces Hardware based timestamp using TWAMP. This feature provides greater accuracy than other time synchronization protocols which enables the service providers to achieve microsecond precision and better performance at scale.

See NCS 560 Content link.

Y.1564 or Ethernet Service Activation (or performance test methodology) is a testing procedure which tests service turn-up, installation and troubleshooting of Ethernet-based services.

Y.1564 allows simultaneous testing of multiple Ethernet services and measures. It validates the different service level agreements (SLAs) to ensure the service meets guaranteed performance settings in a controlled test time. It helps to ensure all the services carried by the network meet the SLA objectives at the maximum committed rate proving that under maximum load, the network devices and paths can support the traffic as designed, even under stress.

See NCS 560 Content Link.

This feature allows MPLS static forwarding over a single-pass GRE tunnel at line rate. One use case is for sending incoming customer traffic over the GRE tunnel, addressed to an anycast virtual IP address (VIP) destination shared by a set of load balancing servers.

See MPLS Over Single-Pass GRE Tunnels.

The PCE Support for MPLS-TE LSPs feature allows Cisco's SR-PCE to act as a Path Computation Element (PCE) for MPLS Traffic Engineering Label Switched Paths (MPLS-TE LSPs).

See .

This feature introduces support for Two-Way Active Measurement Protocol (TWAMP) Light (RFC5357) for link delay and SR policy delay measurement. TWAMP Light adds two-way or round-trip measurement capabilities.

Network performance data such as packet loss, delay and delay variation, and bandwidth utilization is a critical measure for Traffic Engineering (TE). This data provides service providers the characteristics of their networks for performance evaluation that is required to ensure the Service Level Agreements (SLAs). The performance measurement and delay variation feature allows you to measure those metrics and advertise them through IGP extensions as extended TE metrics.

See 560.

With the introduction of this feature, you can set both qos-group and DSCP values within the same QoS policy that is applied in the ingress direction. You can use any permitted value to set the qos-group value.

To set the possible DSCP values for set dscp, configure these values using the following command:

RP/0/RP0/CPU0:ios(config)# hw-module profile qos qosg-dscp-mark-enable 13 15

In the preceding example, only the set dscp 13 and set dscp 15 values are allowed in any QoS policy that contains both set qos-group and set dscp configurations.

Note	Ensure that you reload the router for the hw-module command to be functional.

See .

The command, hw-module profile qos qosg-dscp-mark-enable is introduced.

You must follow these guidelines while enabling FIPS mode:

• You must configure the session with a FIPS-approved cryptographic algorithm. A session configured with non-approved cryptographic algorithm for FIPS (such as, MD5 and HMAC-MD5) does not work. This is applicable for OSPF, BGP, RSVP, ISIS, or any application using key chain with non-approved cryptographic algorithm, and only for FIPS mode (that is, when crypto fips-mode command is configured).

• If you are using any HMAC-SHA algorithm for a session, then you must ensure that the configured key-string has a minimum length of 14 characters. Otherwise, the session goes down. This is applicable only for FIPS mode.

• If you try to execute the telnet configuration on a system where the FIPS mode is already enabled, then the system rejects the telnet configuration.

• If telnet configuration already exists on the system, and if FIPS mode is enabled later, then the system rejects the telnet connection. But, it does not affect the telnet configuration as such.

• It is recommended to configure the crypto fips-mode command first, followed by the FIPS-related commands in a separate commit. The list of commands related to FIPS with non-approved cryptographic algorithms are:

  • key chain key-chain-name key key-id cryptographic-algorithm MD5

  • key chain key-chain-name key key-id cryptographic-algorithm HMAC-MD5

  • router ospfv3 1 authentication ipsec spi 256 md5 md5-value

  • router ospfv3 1 encryption ipsec spi 256 esp des des-value

  • router ospfv3 1 encryption ipsec spi 256 esp des des-value authentication md5 md5-value

  • snmp-server user username usergroup-name v3 auth md5 priv des56

  • ssh server algorithms key-exchange diffie-hellman-group1-sha1

  • telnet vrf default ipv4 server max-servers server-limit

Cisco IOS XR Release 7.1.2 introduces the command logging format bsd which enables the router to send system log messages to a remote server in BSD (Berkeley Software Distribution) format. This enables systems that are dependent on the BSD format to correctly interpret the log message.

The command, is introduced.
