Cisco ASR 1000 Series Aggregation Services Routers are Cisco routers deployed as managed service provide 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.

LAN and WAN MACSec Interop

The LAN-WAN MACsec interoperability feature is supported on the following Cisco devices:

- Cisco ASR1001-X Router

- Cisco 4400 Intergrated Services Routers (With 2-port Wallander NIM)

- Cisco 4300 Intergrated Services Routers (With 2-port Wallander NIM)

- Cisco Catalyst 3850 Series Switches

- Cisco Catalyst 4500-X Series Switch

The topology could be any two devices from the above list that are connected back-to-back (without any intermediate device). The working scenarios for this feature are as follows:

- MKA-MACsec with pre-shared key only for the P2P-port-based deployment model.

- MACsec Cipher Suites supported between ASR/ISR routers and C4500-X is GCM-AES-128 only.

- MACsec cipher suites supported between Cisco ASR 1000 Series Aggregation Services Routers or Cisco 4000 Series Integrated Services Routers and Cisco Catalyst 3850 Series Switches is GCM-AES-128 only. However, Cipher Suite GCM-AES-256 can also be used on some of the Cisco Catalyst 3850 Series Switches (depending on the ASIC used in the device), which do support this interoperability.

MACSec ASR1001-HX Platform Enablement

Cisco ASR 1001-HX Router is a part of the Cisco ASR 1000 Series and offers a compact form factor that consumes less rack space and power while offering 60 Gbps forwarding throughput. Cisco ASR 1001-HX Router supports all general purpose routing and security features of Cisco ASR 1000 Series Aggregation Services Routers.

Effective with Cisco IOS XE Everest 16.4.1, MACsec is supported on Cisco ASR 1001-HX Router.

Site to Site IPSEC VPN for WEBUI

- Site-to-Site VPN—A Virtual Private Network (VPN) allows you to protect traffic that travels over lines that your organization may not own or control.VPNs can encrypt traffic sent over these lines and authenticate peers before any traffic is sent. Site-to-Site VPN feature allows you to create a VPN network connecting two routers.

- Cellular Interface—The Cellular Interface feature supports the Fourth Generation (4G) Long-Term Evolution (LTE) and its primary application is Cellular WAN connectivity, which functions as a primary or backup data link for critical data applications.

- Configuring Application Visibility—Enhanced to include Application Signatures identifier based on NBAR engine version 28. NBAR engine version changes if you update the protocol package.

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
