What is Cisco Nexus used for?
What is Cisco Nexus used for?
The Nexus 3000 is a foundational component of Cisco’s Open Network Environment (ONE) designed to help networks become more open, programmable and application-aware. It offers flexibility, high density, and performance for top-of-rack deployments, supporting mobility and tenant isolation with VXLAN.
What is Nexus FabricPath?
Fabricpath is a Cisco proprietary protocol, found on some of the Nexus switch range, such as the N5K and N7K. Fabricpath is not supported on the N3K or N9K series. These switches support VxLAN based fabric. This is an alternate way to put non-blocking uplinks in place.
What is swid SSID lid?
The numbers correspond to the SWID – Switch ID, SSID – Sub Switch ID and LID – Local ID. The SWID is a unique value assigned per switch what ISIS uses to route traffic within the fabric. The SSID is used when VPC+ is configured and is locally significant to each switch.
What is vPC nexus?
vPC (Virtual Port-Channel), also known as multichassis EtherChannel (MEC) is a feature on the Cisco Nexus switches that provides the ability to configure a Port-Channel across multiple switches (i.e. vPC peers). vPC is similar to Virtual Switch System (VSS) on the Catalyst 6500s.
What is a 5k switch?
The Nexus 5000 series is a range of 5 models 1U or 2U rack-switches offering 20 to 96 interfaces running on 1 or 10 Gbit/s ethernet and 10 Gbit/s FCoE interfaces. They can be used with the above-mentioned Nexus 2000 series fabric extender.
Is OTV supported on Nexus 9000?
The Nexus 9000 switches run NX-OS same as Nexus 7000 and banking on key features like ACI (Application Centric Infrastructure) for allowing the switches to participate in the SDN framework….NEXUS 7K switches vs NEXUS 9K switches.
| PARAMETERS | NEXUS 7K | NEXUS 9K |
|---|---|---|
| OTV and LISP | Supported | Not Supported |
What is the difference between Nexus 7k and 9k?
There are a few key differences between the Cisco Nexus 7000 Series and Nexus 9000 DC switches. The Nexus 9000 supports Application Centric Infrastructure (ACI) in contrast to the Nexus 7000 switches. Finally, it is foreseen that the Nexus 9000 will complement the Nexus 7000 as data centers transition to ACI.
Is FabricPath switching supported on the Cisco Nexus 5000 series devices?
Note FabricPath switching is not supported on the Cisco Nexus 5000 Series devices. FabricPath switching allows multipath networking at the Layer 2 level without using the Spanning Tree Protocol (STP) see Figure 1-1.
Can the Cisco Nexus 5000 series device be the STP root bridge?
• The Cisco Nexus 5000 Series device cannot be the STP root bridge or have any designated nonedge ports in the STP topology. • The Cisco Nexus 5000 Series device and the Cisco Nexus 2000 Fabric Extenders that are undergoing an ISSU must be a leaf on the spanning tree.
Is the Cisco Nexus 5000 a leaf or spine device?
• The Cisco Nexus 5000 Series device and the Cisco Nexus 2000 Fabric Extenders that are undergoing an ISSU must be a leaf on the spanning tree. Note The term “leaf” refers to a device that connects servers in a data center fabric and the term “spine” refers to a device that connects the leaf devices.
Can you configure a VPC+ domain on the same Cisco Nexus 5500 series?
You cannot configure a vPC+ domain and a vPC domain on the same Cisco Nexus 5500 Series switch. A vPC+ domain enables Cisco Nexus 5500 Series switches that have FabricPath enabled to form a single vPC+, which is a unique virtual switch to the rest of the FabricPath network.
