  • Flex LSP

Cisco ASR 920 Series Routers support Flex Label Switched Paths (Flex LSPs).

Flex LSPs are LSP instances where the forward and the reverse direction paths are setup, monitored and protected independently and associated together during signaling. You use a RSVP Association object to bind the two forward and reverse LSPs together to form either a co-routed or non co-routed associated bidirectional TE tunnel.

For more information, see Flex LSP Overview

  • FLEX LSP Layer 2 VPN PW CAC with persistent bandwidth

When you add the persistent keyword to the bandwidth number command, the pseudowire's bandwidth is recovered and is available when the VC is in down state.

There are two ways to configure the persistent bandwidth, you can either configure through template, or under the interface pseudowire directly. If an interface pseudowire is configured with both template and the direct configuration, the direct configuration will overwrite the bandwidth configured through template.

For more information, see Configuring Bandwidth of the Pseudowire with Persistent keyword.

New Hardware Features in Cisco IOS XE 3.17S

  • GPS Support

Effective Cisco IOS-XE Release 3.17, the Cisco ASR-920-12SZ-IM router uses a satellite receiver, also called the global navigation satellite system (GNSS), as a new timing interface. With the GNSS available on the router itself, the access networks can now directly estimate time measurements and clock errors from the satellites. In other words, the Cisco ASR-920-12SZ-IM can now act as a grandmaster clock.

For more information, see Cisco ASR 920 Series Aggregation Services Router Configuration Guide.

New Software Features in Cisco IOS XE 3.17S

  • VLAN Scale with Convergence

The convergence value is improved from Cisco IOS XE 3.17 release.

For more information, see LAN Switching Configuration Guide (Cisco ASR 920 Series).

  • Layer 3 Access Control Lists on EVCs

Access Control Lists (ACLs) provide the capability to filter packets at a fine granularity. In Metro Ethernet networks, ACLs are directly applied on Ethernet virtual circuits (EVCs). Earlier, the layer 3 ACLs were only supported on the routed ports (physical ports or BDIs). Effective Cisco IOS-XE Release 3.17, the support of layer 3 ACLs on EVCs provides the capability to filter the layer 3 packets on layer 2 bridges that support Ethernet services.

For more information, see MPLS: Layer 3 VPNs Configuration Guide.

  • VLAN Translation with QoS

Effective Cisco IOS-XE Release 3.17, VLAN translation provides flexibility in managing VLANs and Metro Ethernet-related services. The current implementation of the feature allows one or more 802.1Q tags to be replaced with other 802.1Q tags and thus the desired tag manipulation can be achieved. In a scenario with two EFPs egressing the same interface, each EFP can have a different VLAN rewrite operation, which is more flexible.

For more information, see Carrier Ethernet Configuration Guide.

  • Transparent CFM on C-VLAN

Transparent CFM is a mechanism to provide transparency on CFM frames between customer ends. Transparency helps the service provider network to pass the entire maintenance levels (0-7) of CFM frames from one customer end to another customer end by UP MEP that is configured on UNI-N port at any level.

For more information, see Carrier Ethernet Configuration Guide.

  • Ethernet Fault Detection

Ethernet Fault Detection (EFD) is a mechanism that allows Ethernet OAM protocols, such as CFM, to control the “line protocol” state of an interface. Unlike many other interface types, Ethernet interfaces do not have a line protocol, whose state is independent from that of the interface. For Ethernet interfaces, this role is handled by the physical-layer Ethernet protocol itself, and therefore if the interface is physically up, then it is available and traffic can flow.

EFD changes this to allow CFM to act as the line protocol for Ethernet interfaces. This allows CFM to control the interface state so that if a CFM defect (such as AIS or loss of continuity) is detected with an expected peer MEP, the interface can be shut down. This not only stops any traffic flowing, but also triggers actions in any higher-level protocols to route around the problem.

For more information, see Carrier Ethernet Configuration Guide.

  • Configuring Multicast VPN

The Multicast VPN (MVPN) feature provides the ability to support multicast over a Layer 3 VPN. IP multicast is used to stream video, voice, and data to an MPLS VPN network core.

For more information, see IP Multicast: PIM Configuration Guide (Cisco ASR 920 Series).

  • Multicast VPN Extranet Support

The Multicast VPN Extranet Support feature enables service providers to distribute IP multicast content originated from one enterprise site to other enterprise sites.

This feature enables service providers to offer the next generation of flexible extranet services, helping to enable business partnerships between different enterprise VPN customers.

For more information, see IP Multicast: PIM Configuration Guide (Cisco ASR 920 Series).

  • SLM/DMM over VPLS

Synthetic loss measurement (SLM) and Delay Measurement Message (DMM) are part of the ITU-T Y.1731 standard. SLM is used to periodically measure Frame Loss and Forward Loss Ratio (FLR) between a pair of point to point MEPs. DMM is used to periodically measure Frame Delay and Frame Delay Variation between a pair of point to point MEPs.This feature enables the configuration of SLM/DMM over VPLS.

For more information, see IP SLAs Configuration Guide.

  • ATM/IMA

In Inverse Multiplexing over ATM (IMA), the originating stream of ATM cells is divided so that complete ATM cells are transmitted in round-robin order across the set of ATM links.

For more information, see Asynchronous Transfer Mode Configuration Guide, Cisco IOS XE Release 3S (Cisco ASR 920 Series).

  • MPLS TE over BDI

Effective Cisco IOS-XE Release 3.17, the Cisco ASR-920-12SZ-IM router provides the option for enabling the MPLS TE tunnels over Bridge Domain Interfaces.

For more information, see MPLS Basic Configuration Guide (Cisco ASR 920 Series).

For more information, see Carrier Ethernet Configuration Guide (Cisco ASR 920 Series).

  • Policy-Based Routing

This feature provides a way for a device to put packets through a route map before routing them.

The route map determines which packets are routed to which device. You might enable policy-based routing (PBR) if you want some packets to be routed a way other than the obvious shortest path. PBR provides control over routing by extending and complementing the existing mechanisms provided by routing protocols. Possible applications for PBR are to provide equal access, protocol-sensitive routing, source-sensitive routing, routing based on interactive versus batch traffic, and routing based on dedicated links.

For more information, see IP Routing: Protocol-Independent Configuration Guide, Cisco IOS XE Release 3S (Cisco ASR 920 Series) .
