We have similar setup with two Nexus 7K switches, We are not using VPC, we are using HSRP in layer two to cross connect our Nexus switches. End with CNTL/Z. A performance impact or outage is experienced when accessing the storage system through the LAN after implementing Cisco's vPC on Nexus 7000 or 5500 series switches, when ip. This lets us utilize both switches and introduce high failure resiliance. Here are some of the design considerations I've encountered, and my preferred solution to each. A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus™ 5000 Series devices to appear as a single PortChannel to a third device. SPAN ports are commonly used for network traffic analysis applications. Setup a VPC correctly on Cisco Nexus Switches with Fabricpath November 20, 2014 November 13, 2014 by Vince VPC: Virtual Port Channel – this is a port channel that instead of connecting multiple ports only on one switch, you are spreading it over two physical switches. engages in the 1 last update 2019/08/26 design, manufacture, and marketing of mobile communication, media devices, personal computers, and portable digital music players. I have a customer who wanted to do inter-VLAN routing at the distribution layer (Nexus 5K) on his Nexus solution about a month ago. Configuration synchronization, also known as Switch Profiles, is a new feature that has been introduced by Cisco to primarily support Nexus vPC Domain topologies in modern data centers, specifically the Dual-Homed FEX scenarios. In the vPC domain configuration mode, enter the fabricpath switch-id switch-id command. The two Cisco Nexus® 7000 Switches at the core are acting as a Layer 2 and Layer 3 boundary: they allow routing between VLANs or to the outside of the network. Here's a nice Cisco Nexus guide which I used to quickly get started and a link for the best practice configuration for the NX-OS STP extensions or the spanning-tree port type. 92Tbps of throughput, or simply as an upgrade from the traditional Catalyst 6509 chassis, you will definitely want to take advantage of its Virtual Port-Channel (vPC) capability. Each FEX connected to both Nexus 5548UP's via vPC as well. Configure vPC in the plugin with multiple. Cisco Nexus 1000v Secondary VSM Setup; Cisco Nexus 5000. Step 1 activate vpc feature; Step 2 Create VRF “vpc” and create an L3 keepalive link between the two Nexus switches. But similar to VSS it's recommended to implement out-of-band management for Nexus switches, otherwise one could become completely unreachable in case of vPC incosistencies. For example, rebooting the Cisco Nexus device and any connected FEX causes a disruption. Rather, Layer 3 routed interfaces with ECMP should be configured. Posted on March 13, 2014 March 12, 2014 by Ryan I previously had the chance to play around with the 5596UP switch, and made some notes on how to configure inter-vlan routing. This is the one we want to upgrade first. The Nexus 7000 supervisor module is based on an Intel dual-core processor that enables a scalable control plane. In this Cisco Certificate Training the students will get hands on instructions on Configuring Cisco Nexus 7000 Switches (DCNX7K) v3. The Configuring Cisco Nexus 7000 Switches (DCNX7K) v3. A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus 7000 or 5000 Series devices to appear as a single PortChannel to a third device. All of these features are unique in Cisco Nexus 7000 and Cisco Nexus 5000. Cisco UCS with Nexus VPC Cisco Nexus 3000k pair. Cisco vPC aka Virtual Port-Channel, which was launched in 2009 is a feature on the Cisco Nexus series switches that allows end device to configure a Port-Channel across multiple switches. Quick notes on the “inactive” port status seen on the Cisco Nexus platform, which was perplexing the first time I ran into it. I was setting up Netapp FAS3020 with LACP VIF and creating a VPC on the nexus ( 4 links from filer and 2 links to each nexus). interface ethernet 3/10 switchport switchport mode trunk switchport trunk allowed vlan 1-50 switchport trunk native vlan 6 channel-group 40 mode active exitinterface port-channel 40 vpc 40 exit. One of the main requirements in Dual-Homed FEX topologies is configuration consistency across both Nexus 5K switches.

The vPC is actually eleminate the need of STP on the member vPC ports and allow for efficient loadsharing capabilities. The basic configuration of the two Nexus 5k switches is done. Posted on August 31, 2011 Updated on September 14, 2015. Cisco Nexus 5596's with Redundant Uplinks to Catalyst 6509 Core's Using vPC. The two Cisco Nexus switches involved in a VPC differ from stacking or VSS technology in that stacking and VSS create a single data and control plane across the multiple switches, whereas VPC creates a. This article compares the initial setup and installation of a Cumulus Linux switch against a Cisco Nexus 3000 switch. One of the things we are doing is replacing the Cisco 6500s and putting in Nexus 7Ks, along with 5Ks and FEXs. On the switch side ehter channel is set to ON. Nexus is a modular network switch introduced on January 28, 2008 Designed for the data center (optimized for high-density 10 Gigabit Ethernet. About this task Configure the spanning tree mode on the port channels appropriately. Nexus# conf t Enter configuration commands, one per line. Tagged on: Cisco Nexus vPC. The adjacent physical switches require vPC capability (for example, a Cisco Nexus 5000 Series Switch), in which they. The Cisco Nexus 7000 series supervisor module is designed to deliver scalable control plane and management functions for the Cisco Nexus 7000 Series chassis. To disable spanning tree on the Cisco ports your Flex-10 switches are connected to you need to configure the following: Remember if you are using a LACP Group or a Nexus vPC make the configuration changes on the LACP/vPC Group rather than on the individual ports. FAQ: HSRP Behavior on Nexus vPC Cisco Forum. vPC configuration is made up of three main components, the vPC Peer Keepalive Link, the vPC Peer Link, and the vPC Member Ports. Configure vPC Peer-keepalive. This post will show you how to fix the LACP “BUG” on the NX-OSv 9000 so that you can LACP to whatever devices you want. By default, Cisco Nexus 5500 switches dynamically reacts to any FEX connectivity changes - they remove any configuration commands for the non-existing interfaces (this happens when FEX is not connected). Nexus vPC is a treamendous cisco feature that introduced with Nexus 2,5 and 7K. So when I was looking at configuration examples I noticed some confusion between a dual-homed FEX setup and an enhanced vPC setup, so I’ll try to clear the air. vPC belongs to Multichassis EtherChannel [MCEC] family of technology. Most Important port must be there is : Keep Alive Port: this port function to take care heard beat between to switch, this keep-alive port must dedicated VRF in this example I…. What we’re used to seeing from Cisco is a 4-step process of defining your NetFlow record, defining your NetFlow exporter, creating your monitor and applying the monitor to an interface. However, there is another important feature using HSRP/VRRP protocols in the context of vPC: the Layer2 dual–active peer devices. I couldn't find all this at one place in the Cisco documentation (maybe I didn't look hard enough:) so I decided to put it here for those needing a quick fact check: 1. The two Cisco Nexus® 7000 Switches at the core are acting as a Layer 2 and Layer 3 boundary: they allow routing between VLANs or to the outside of the network. vPC member port One of a set of ports (that is, port-channels) that form a vPC (or port-channel member of a vPC). A Virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus switches to appear as a single portchannel to the connected device (host or a Classic Ethernet (CE) switch). Nexus vPC on the other hand utilizes a virtual Port Channel (vPC), allowing links that are physically connected to two different Cisco Nexus™ Series devices to appear as a single Port Channel to a third device.
