Cisco ASR 920 Series Routers Overview

The Cisco ASR 920 Series Aggregation Services Routers provide a comprehensive and scalable set of Layer 2 and Layer 3 VPN services in a compact package. They are temperature-hardened, small form factor, with high throughput and low power consumption ideal for mobile backhaul, business services and residential voice, video, and data ("triple-play") applications.

Software Licensing Overview

Starting with Cisco IOS XE Cupertino 17.7.1, PAK licenses are no longer available. When you purchase the Cisco IOS XE Cupertino 17.7.1 release or later, Smart Licensing is enabled by default. We recommend that you move to Smart Licensing before upgrading to Cisco IOS XE Cupertino 17.7.1 or a higher release, for a seamless experience.

If you are using Cisco IOS XE Bengaluru 17.6.1 or an earlier release version, Smart Licensing is not enabled by default. To enable Smart Licensing, see Software Activation Configuration Guide (Cisco IOS XE ASR 920 Routers).

The router offers the following base licenses:

  • Metro Services

  • Metro IP Services

  • Advanced Metro IP access

    • SDM Video Template

Limitations and Restrictions on the Cisco ASR 920 Series Routers

  • The default interface command is used to default the parameters under that interface. However, when speed is configured on the interface, the following error is displayed: 

    Speed is configured. Remove speed configuration before enabling auto-negotiation

  • Adding or deleting the Trunk Ethernet flow points (TEFPs) with scaled bridge-domain, without delay causes the Cisco ASR 920 Series router to crash.

  • Virtual services should be deactivated and uninstalled before performing replace operations.

  • The Cisco ASR920 Series Routers no longer support the controller and nid-controller commands for the Cisco ME1200 switch.

  • The following interface modules (IMs) do not require the activation command for IM boot up, provided no other IM is activated in subslot 0/1 before.

    However, if an IM was activated in the system earlier, deactivate the previously-activated IM before inserting a new IM in system.

    • 16-Port T1/E1 Interface Module

    • 32-Port T1/E1 Interface Module

    • 8-Port T1/E1 Interface Module

    • 4-port OC3/STM-1 (OC-3) or 1-port OC12/STM-4 (OC-12) Interface Module

    • 14-Port Serial Interface Module

    • 6-Port E and M Interface Module

    • 4-Port C37.94 Interface Module

  • RS422 works on ports from 0 to 7 only.

  • The following restriction is applicable only to Cisco ASR-920-24SZ-IM, Cisco ASR-920-24SZ-M, and Cisco ASR-920-24TZ-M.

    • Traffic is dropped when packets of size 64 to 100 bytes are sent on 1G and 10G ports.

      • For 64-byte packets, traffic drop is seen at 70% and beyond of the line rate.

      • For 90-byte packets, traffic drop is seen at 90% and beyond of the line rate.

      • For 95-byte packets, traffic drop is seen at 95% and beyond of the line rate.

    • Traffic is dropped when:

      • Traffic is sent on a VRF interface.

      • Traffic is sent across layer 2 and layer 3.

    However, traffic is not dropped when the packet size is greater than 100 bytes, even if the packets are sent bidirectionally at the line rate.
