Product Information

Layer 2 Handoff—This feature of connects a traditional network with an SD-Access network. This feature can be used during transitions and migrations in concert with the following approach. Both VLAN and SGT assignment can be received dynamically as a result of the endpoint authentication and authorization process. This allows traffic between sources in the same VLAN and in different VLANs to be enforced on the policy extended node itself. Segmentation to other sources in the fabric are provided through inline tagging on the 802.1Q trunk connected to the upstream fabric edge node. When working with different products to remove glues, always do a test first to make sure they won’t harm your clothes. After the test is done for this glue, spread some nail polish remover on the glue. Additional devices such as the Cisco Catalyst 4500, 6500, and 6800 Series and Cisco Nexus 7700 Series are also supported, but there may be specific supervisor module, line card module, and fabric-facing interface requirements.

Organizations can deploy both centralized and SD-Access Wireless services as a migration stage. Cisco DNA Center can automate a new installation supporting both services on the existing WLC, though a software WLC software upgrade may be required. In this case, the new installation from Cisco DNA Center on the existing WLC does not take into consideration existing running configurations. Instead, Cisco DNA Center automates the creation of the new replacement services.The SD-Access architecture is supported by fabric technology implemented for the campus, enabling the use of virtual networks ( overlay networks) running on a physical network ( underlay network) creating alternative topologies to connect devices. This section describes and defines the word fabric, discusses the SD-Access fabric underlay and overlay network, and introduces shared services which are a shared set of resources accessed by devices in the overlay. This section provides an introduction for these fabric-based network terminologies used throughout the rest of the guide. Design consideration for these are covered in a later section. Some physical locations may use unique wiring plans such that the MDF and IDF do not conform to the common two-tier and three-tier hierarchical network structure. The result is that the available fiber and copper wiring may require access switches to be daisy-chained or configured in a ring. Any number of wiring variations may exist in a deployment. Due to the unique nature of supporting all three fabric roles on a node, Fabric in a Box has specific topologies that are supported if additional fabric edge nodes or extended nodes are connected to it (downstream from it). The topologies supported differ based on if SD-Access Embedded wireless (now a fourth fabric role on the device) is also implemented. Increased capacity of wireless access points—The bandwidth demands on wireless access points (APs) with the latest 802.11ac Wave 2 and 802.11ax (Wi-Fi 6) technology now exceed 1 Gbps, and the IEEE has now ratified the 802.3bz standard that defines 2.5 Gbps and 5 Gbps Ethernet. Inline tagging is the process where the SGT is carried within a special field known as CMD (Cisco Meta Data) that can be inserted in the header of the Ethernet frame. This changes the EtherType of the frame to 0x8909. If the next-hop device does not understand the this EtherType, the frame is assumed to be malformed and is discarded. Inline tagging can propagate SGTs end to end in two different ways.

Network virtualization—A LISP Instance ID (IID) is used to maintain independent VRF and VLAN topologies. From a data-plane perspective, the LISP Instance ID maps to either a Layer 2 or Layer 3 VNI.IP voice/video collaboration services—When IP phones and other unified communications devices are connected in multiple virtual networks, the call control signaling to the communications manager and the IP traffic between those devices needs to be able to traverse multiple VNs in the infrastructure. Interface MTU should be set consistently across a Layer 2 domain (collision domain/VLAN) to ensure properly communication. Consistent MTU is also required for several other processes and protocols to work properly such as OSPF and IS-IS. In a University example, students and faculty machines may both be permitted to access printing resources, but student machines should not communicate directly with faculty machines, and printing devices should not communicate with other printing devices. Layer 2 access networks provide the flexibility to allow applications that require Layer 2 connectivity to extend across multiple wiring closets. This design does come with the overhead of Spanning-Tree Protocol (STP) to ensure loops are not created when there are redundant Layer 2 paths in the network. Access points and other Power over Ethernet (PoE) devices can be connected directly to both variants of extended node switches. When connecting PoE devices, ensure that there is enough available PoE power available. This is especially true with Industrial Ethernet Series switches which have significant variety of differing powering options for both AC and DC circuits.

By default, when a network access device (NAD) cannot reach its configured RADIUS servers, new hosts connected to the NAD cannot be authenticated and are not provided access to the network. The inaccessible authentication bypass feature, also referred to as critical authentication, AAA fail policy, or simply critical VLAN, allows network access on a particular VLAN when the RADIUS server is not available (down). Wool is a hardy fabric and it can handle some rough glue removal treatments. One that you have already read about works on this fabric as well. Use a cloth or cotton ball and dab some nail polish remover onto the glue and wait. LAN Automation is designed to onboard switches for use in an SD-Access network either in a fabric role or as an intermediate device between fabric nodes. The LAN Automation process is based on and uses components from the Cisco Plug and Play (PnP) solution. While understanding the full Cisco PnP solution is not required for provisioning and automation, understanding the pieces aids in network design. After this use, some Persil liquid and place it directly onto the glue. Then wash the garment like normal. Repeat as necessary as this formula should not harm your fabric unless it is vulnerable to acetone. Remove Eyelash Glue From Fabric The key advantage of using link aggregation is design performance, reliability, and simplicity. With the Ethernet bundle comprising up to eight links, link aggregation provides very high traffic bandwidth between the controller, servers, applications, and the remainder of the network. If any of the individual ports fail, traffic is automatically migrated to one of the other ports. If at least one port is functioning, the system continues to operate, remain connected to the network, and is able to continue to send and receive data.Anycast RP Technology White Paper: https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers/anycast.html The seed device should have SSH enabled along with SSH credentials and SNMP read credentials configured. SNMPv2 is supported though SNMPv3 is recommended. While a single seed can be defined, two seed devices are recommended. The secondary seed can be discovered and automated, although most deployments should manually configure a redundant pair of core or distribution layer switches as the seed and peer seed devices.

Getting glue on your fine or everyday fabrics is nothing to get upset about. As you can see the removal processes are very easy to do and you may have the removers in your home right now. As new devices are deployed with higher power requirements, such as lighting, surveillance cameras, virtual desktop terminals, remote access switches, and APs, the design should have the ability to support power over Ethernet to at least 60W per port, offered with Cisco Universal Power Over Ethernet (UPOE), and the access layer should also provide PoE perpetual power during switch upgrade and reboot events. New endpoints and building systems may require even more power, and IEEE 802.3bt and Cisco UPOE-Plus (UPOE+) can provide power up to 90W per port. Both fixed configuration and modular switches will need multiple power supplies to support 60–90W of power across all PoE-capable ports. Starch is another top contender and it is easy to find in your supermarket. A double dose of starch on the edges of fabric should keep all the threads in line and the material looking good. Mapping of user to virtual network—Endpoints are placed into virtual networks by assigning the endpoint to a VLAN associated to an SVI that is forwarding for a VRF. Together, these make up the Layer 2 and Layer 3 LISP VNIs, respectively, which maintain fabric segmentation even at the control plane communication level. The transit control plane nodes cannot be collocated with any other fabric role. They should be highly available through redundant physical connections. Routing platforms should have at least 8GB and preferably 16 GB or more DRAM to store all the registered prefixes for the entire fabric domain.Virtual Networks (Macro-segmentation)—Use virtual networks when requirements dictate isolation at both the data plane and control plane. In general, if devices need to communicate with each other, they should be placed in the same virtual network. If communication is required between different virtual networks, use an external firewall or other device to enable inter-VN communication. Virtual Network provides the same behavior and isolation as VRFs. SD-Access supports two options for integrating wireless access into the network. One option is to use traditional Cisco Unified Wireless Network (CUWN) local-mode configurations over-the-top as a non-native service. In this mode, the SD-Access fabric is simply a transport network for the wireless traffic, which can be useful during migrations to transport CAPWAP-tunneled endpoint traffic from the APs to the WLCs. The other option is fully integrated SD-Access Wireless, extending the SD-Access beyond wired endpoints to also include wireless endpoints. Extended nodes offer a Layer 2 port extension to a fabric edge node while providing segmentation and group-based polices to the endpoints connected to these switches. Endpoints, including fabric-mode APs, can connect directly to the extended node. VLANs and SGTs are assigned using host onboarding as part of fabric provisioning.
