New and Changed Features

This section describes the new features introduced in Cisco Dynamic Fabric Automation 1.0.

Cisco Dynamic Fabric Automation 1.0 includes the following four modular and independent functions for simplifying, optimizing, and automating the Data Center fabric environment:

1. Fabric Management—offers new levels of management, simplifies workload visibility, optimizes troubleshooting, and automates fabric component configuration.

2. Workload Automation—integrates with automation and orchestration tools through northbound APIs. In addition, it offers a level of control for fabric component provisioning through the automatic application of templates, leveraging southbound APIs and/or standard based protocols. This mechanism is also extensible to network services.

3. Optimized Networking—offers Layer 2 switching and Layer 3 routing concurrently. With optimized networking, your network has smaller failure domains with subnets that support Layer 2 switching and Layer 3 routing concurrently when you use a simple distributed gateway mechanism.

4. Virtual Fabrics—offer logical fabric isolation and segmentation within the fabric, by extending the boundaries of segmented environments to different routing and switching instances. These technologies can be combined to support hosting, cloud, and/or multitenancy environments.

Limitations

The limitations of Cisco Dynamic Fabric Automation 1.0 are as follows:

•Cisco DFA requires a minimum of one multiprotocol Border Gateway Protocol (BGP) route reflector.

•Every Cisco DFA node, which is intended to be managed by fabric management, needs to connect through an Ethernet out-of-band port (mgmt0) to this network.

•Console connection for management is recommended but not required for Cisco DFA.

•In order to avoid Cisco DFA device autoconfiguration interfering with other DHCP servers, we recommend that you use a dedicated VLAN and subnet for an enhanced fabric management network. Cisco Data Center Network Manager (DCNM) as well as the Ethernet out-of-band port of the DFA nodes (for example, mgmt0) will reside in the enhanced fabric management network. You have the option to interconnect the enhanced fabric management network with your existing out-of-band management network.

•The Cisco Nexus 5000 Series supports the following:

–L2 only DFA leaf.

–L3 Anycast gateway via a Cisco Nexus 6000 DFA leaf .

–Fabric Management as a DFA leaf by DCNM 7.0.

---

Note The Cisco Nexus 5000 Series does not support auto-configuration.

•The Cisco Nexus 5000 Series does not support Segment ID.

Caveats

This section includes the following topics:

•Cisco Bug Search

•Open Caveats—Cisco Dynamic Fabric Automation 1.0

Cisco Bug Search

Bug Search Tool (BST), the online successor to Bug Toolkit, is designed to improve our customers' effectiveness in network risk management and device troubleshooting.

BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The service has provision to filter bugs based on credentials to provide external and internal bug views for the search input.

Please check out Bug Search Tools & Resources on Cisco.com. For more details on the tool overview and functionalities, check out the help page, located at http://www.cisco.com/web/applicat/cbsshelp/help.html.

Open Caveats—Cisco Dynamic Fabric Automation 1.0

•CSCul28424

Symptom: In a DFA enhanced multicast environment, duplicate packets will be sent out on fabric, where host VLAN is enabled with fabricpath and PIM.

Condition: In a DFA enhanced multicast environment, if host VLAN is fabricpath and PIM enabled, duplicate packets will be sent out on fabric. We currently do not support enabling PIM on fabricpath VLANs in DFA enhanced multicast environment.

Workaround: Do not explicitly configure PIM on host VLANs in a DFA enhanced multicast environment.

•CSCum37744

Symptom: In a DFA enhanced multicast environment, if DFA border leafs are in VPC+ mode, duplicate packets may be sent towards the receivers.

Conditions: This happens in a DFA enhanced multicast environment, if DFA border leafs are in VPC+ mode.

Workaround: Deploy border leafs in a non-VPC+ mode.
