Cisco ASR 1000 Series Aggregation Services Routers are Cisco routers deployed as managed service provider routers, enterprise edge routers, and service provider edge routers. These routers use an innovative and powerful hardware processor technology known as the Cisco QuantumFlow Processor.

Cisco ASR 1000 Series Aggregation Services Routers run the Cisco IOS XE software and introduce a distributed software architecture that moves many operating system responsibilities out of the IOS process. In this architecture, Cisco IOS, which was previously responsible for almost all of the internal software processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE processes to share responsibility for running the router.

Extensible Authentication Protocol - Transport Layer Security (EAP-TLS) method support for MACsec Key Agreement (MKA)

The Extensible Authentication Protocol - Transport Layer Security (EAP-TLS) method support for MACsec Key Agreement (MKA) feature uses 802.1X port-based authentication with Extensible Authentication Protocol – Transport Layer Security (EAP-TLS) to carry certificates for router ports where MACsec encryption is required. EAP-TLS mechanism is used to do the mutual authentication and to get the master session key (MSK) from which the connectivity association key (CAK) is derived for the MACsec Key Agreement (MKA) protocol.

WEB User Interface

Supports an embedded GUI-based device-management tool that provides the ability to provision the router, simplifies device deployment and manageability, and enhances user experience. The following features are supported on Web User Interface from Cisco IOS XE Everest 16.6.1:

  • Cisco Umbrella Branch—The Cisco Umbrella Branch feature enables cloud-based security service by inspecting the Domain Name System (DNS) query that is sent to the enterprise DNS server through the Cisco 4000 Series Integrated Services Routers (ISR). The security administrator configures policies on the Cisco Umbrella Branch cloud to either allow or deny traffic towards the fully qualified domain name (FQDN). Cisco 4000 Series ISR acts as a DNS forwarder on the network edge, transparently intercepts DNS traffic, and forwards the DNS queries to the Cisco Umbrella Branch cloud.

  • Dynamic Multipoint VPN—The Dynamic Multipoint VPN feature allows users to better scale large and small IP Security (IPsec) Virtual Private Networks (VPNs) by combining generic routing encapsulation (GRE) tunnels, IPsec encryption, and Next Hop Resolution Protocol (NHRP).

  • Snort IPS/IDS—The Snort IPS feature enables Intrusion Prevention System (IPS) or Intrusion Detection System (IDS) for branch offices on Cisco 4000 Series Integrated Services Routers and Cisco Cloud Services Router 1000v Series. This feature uses the open source Snort solution to enable IPS and IDS.

  • Zone-Based Firewall—Allows you to easily manage Cisco IOS unidirectional firewall policy between groups of interfaces known as zones.

Caveats

Open and Resolved Bugs

The open and resolved bugs for a release are accessible through the Cisco Bug Search Tool. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. Within the Cisco Bug Search Tool, each bug is given a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). The bug IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific bug. The Cisco Bug Search Tool enables you to filter the bugs so that you only see those in which you are interested.

In addition to being able to search for a specific bug ID, or for all bugs in a product and release, you can filter the open and/or resolved bugs by one or more of the following criteria:

  • Last modified date

  • Status, such as fixed (resolved) or open

  • Severity

  • Support cases

You can save searches that you perform frequently. You can also bookmark the URL for a search and email the URL for those search results.
