Basic topology two Nexuses with VPC link between them and MGMT interfaces connected to OOB switch: 2. Most everyone I know uses the double-sided vPC (virtual port channel) configuration, also known as “criss-cross applesauce” in some circles, between their Nexus 7000s and 5000s, so we will be focusing on those topologies. In the vPC domain configuration mode, enter the fabricpath switch-id switch-id command. A Cisco Nexus 5K vPC acts as a single switch for a Portchannel, but originates two different Bridge IDs. 1. 1. # show vpc brief Legend: (*) - local vPC is down, forwarding via vPC peer-link vPC domain id : 1 Peer status : peer adjacency formed ok vPC keep-alive status : peer is alive Configuration consistency status : success Per-vlan consistency status : success Type-2 On the final vPC config on the Nexus 5010, the interface e1/1 is in the wrong channel-group (should be 1 and not 100). 2(1) called vPC auto-recovery. The first step in configuring vPC is to create a domain with an id number (must match on both switches) and assign a non-preemptive role priority to each switch where lowest number = highest priority. The peer-link must include at least 2 interfaces. In this video, we configure vPC on real Cisco Nexus 9000 switches. Firstly you have to realise that the Nexus 2000 FEXs are simply considered “line cards” in the Nexus 5000. The Nexus 1000V VEM learns via CDP that Eth 1/1 and Eth 1/2 are connected to separate physical switches and creates a “Sub Group” unique to each physical switch. cisco. g. The thing with VPC on the Nexus and FEXes: you can either VPC the FEX to both 5k, or VPC something else off the FEX. This topolgy tinyVdc1(config)# vpc domain 12 tinyVdc1(config-vpc-domain)# peer-keepalive destination 192. vPC knows a few mechanisms to ensure correct operation of the vPC domain.

The jumbo frame configuration steps are different for layer-2 and layer-3 interfaces. auto-recovery. A VPC can be formed not only in the upstream direction but downstream as well, resulting in one massive port-channel among two aggregation switches and two access switches in a grotesque orgy of redundant layer two connectivity. 17 source 172. switch(config-vpc-domain)#exit 2. I've been tasked to research the features and functionality to see if our NX-OS hardware labs could be run on CML. 0. 20. You will also notice that I have spread the channel over two line cards. When not using Nexus hardware use the following dummy configuration verbatim: [NEXUS_SWITCH:1. Beside the Nexus 7000 there are also other models in the Nexus range. It should be configured on both vPC switches because you cannot predict which switch is the vPC secondary on some later time. 1(3)N1(1) OL-25842-01 Cisco Prime DCNM 7. In my case, i am using open source snmp server named SnmpB to test the snmp v3 configuration. vPC domain Domain containing the 2 peer devices. peer-switch. For example, the vPC+ and HSRP configurations on Cisco FabricPathswitches 11 and 12 are shown here. This VLAN for the L3 adjacency should only be forwarded on the peer-link. Before moving forward, check the keepalive status with show vpc peer-keepalive command, if you already configured also your second Nexus switch, you should see a status as “Success” just like below. 10. If we configure port 3, then port 4 will be non-operational. A vulnerability in the Fibre Channel over Ethernet (FCoE) N-port Virtualization (NPV) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. 23. For management access, Cisco Nexus Series switches can be managed in-band, via a single serial console port, or through a single out-of-band 10/100/1000-Mbps Ethernet management port. 2.

Configure VLANs 2. Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide, Release 6. 15. vPC with physical multichassis EtherChannel trunk (MCT) feature is supported for the IPv6 underlay network in DCNM. Configuring vPC across two VDCs on the same Nexus 7000 switch is not supported. 11. Diagram #1 below shows two Nexus 7000’s configured as vPC peers with a single inter-switch link between them, the vPC peer link. Currently I have mesh routing built out where each Nexus has its own BGP neighborship to its peers, ie for each peer I need to build two neighborships. This example demonstrates how to configure the destination, source IP address, and VRF for the vPC-peer-keepalive link: switch# configure terminal switch(config)# feature vpc switch(config)# vpc domain 100 switch(config-vpc-domain)# peer-keepalive destination 172. 1(1). Two switches of the same model can be combined into a VPC pair, which can establish a single EtherChannel, also known as a link aggregate or a port channel, across both switches to a third switch or server. VPC Consistency Check and failover Scenarios Cisco Fabric Services (CFS) Protocol: Cisco Fabric Services CFS is the reliable protocol performs the following functions: Configure validation and comparison (consistency check) Synchronization of MAC addresses for vPC member ports; vPC member port status advertisement; Spanning Tree Protocol management Description (partial) Symptom: Configuring a VPC peer-keepalive on the non-mgmt0 interface will successfully take the configuration, but will not function and will show as suspended. One of the things we are doing is replacing the Cisco 6500s and putting in Nexus 7Ks, along with 5Ks and FEXs. switchport mode trunk. Enable vPC peer-link 9. Before we can define an orphan port, it's important to cover a few vPC concepts. The two Nexus 7000’s are configured for OSPF and are using an SVI associated to a VLAN on the peer-link to form the L3 adjacency. Introduction. Nexus 7000 incorporates a loop hindrance methodology that drops traffic traversing the peer link (destined for a vPC peer link) once there aren’t any failing vPC ports or links. Supported destination devices - You can connect a VXLAN fabric to Cisco Nexus and non-Nexus devices. 100. Configure Layer 3 redundancy and for this example, I’m going to use VRRP: interface Vlanxxx (VRRP is configured per VLAN) no shutdown. References⌗ Hat tip to Adam Raffe for his excellent blog post on this Symptom: When the vPC port-channel is shut down on one side, the peer switch vPC remains up. Figure 1: Layer 2 Setup for OSPF routing over vPC 10 Build from the > core outwards. Configure a vPC Use any available Ethernet port to form a Cisco vPC enabled port channel on Cisco Nexus switches. In turn, this brings the relevant interfaces on the other switch into vPC inconsistent state even though the FEX is still connected to it; The respective configuration is shown below. MGMT interface configuration: N5K-A(config)# int mgmt 0 N5K-A(config-if)# ip address 192. 2. 1] #- Provide the Nexus login credentials username = admin password = mySecretPasswordForNexus #- Baremetal config only - Provide pool of vpc ids for use when creating # port-channels. 1 source 192. 1: icmp_seq=0 ttl Configure a Cisco vPC Use any available Ethernet port to form a Cisco vPC enabled port channel on Cisco Nexus switches. 2(x) Cisco Nexus vPC – Configuration & Failure Scenarios.

The verdict is still out on this one, as I haven't yet had any experience configuring a VPC in a production environment. With dual-homed FEX, every port is considered to be a part of a virtual port-channel. Today we will learn Best Practices for VPC on Cisco Nexus switches. Creating the switch profile is quite easy, instead of using the config t command you use the config sync command. com Contents vii Cisco Nexus 7000 Series NX-OS Interfaces Command Reference, Release 5. 1(1). 10. Have you wondered 'how does #vPC work?' This video is for you!vPC is a way of adding layer-2 resiliency to the data centre. Before we go into the configuration of vPC I wanted to mentioned that the Nexus 5600 series switch is a newer product in the Cisco Data Center portfolio. Verify that the Cisco vPC that must be modified is up. Cisco strongly recommends that you enable this feature to help prevent dual active scenarios, so we’ll enable it. Enable vPC feature1. Include the following information (see the example below): The IP address of the switch. One of the is the vPC Consistency check. nexus. With all the insights from the online document and this forum, I know that I could use `no lacp suspend-individual` to configure the port channel so that DHCP and PXE Single-sided vPC: In single-sided vPCs, each Nexus 5000 switch connects to a pair of Nexus 7000 aggregation switches using a unique vPC, but the Nexus 5000 switches do not run vPC themselves. vPC belongs to Multichassis EtherChannel [MCEC] family of technology. Nexus vPC output.

I can either VPC each fortigate to both Nexus, diagram on the left. Virtual Device Contexts (VDC) is a CISCO protocol for Nexus 7000 series, which allow a Nexus switch to be logically segmented into virtul switches. uk Cisco Virtual Port Channel (vPC) technology enables multichassis link aggregation (MLAG) in Nexus 5500 data center switches. New Question Refer to the exhibit You configure a vPC between two Cisco Nexus from COMPUTERSC 51 at Harvard University Configuration for the Nexus switches First thing to do is enable the vPC feature: feature vpc Once you have enabled the vPC feature, you should create your keep-alive links. 2 and the Cisco Nexus 9000 Series devices support Python v2. VDC helps in partition a single physical device to multiple logical devices which acts as unique and independent switch and has its own configuration and can be managed by separate administrator. Cisco Nexus series switch connectivity information (IP address/console information), log in credentials and access method (SSH/TELNET). Misunderstanding this aspect of vPC operation can lead to unnecessary downtime because of some of the funny behavior associated with orphan ports.

N5k-1 (config)# vpc domain 2 N5k-1 (config-vpc-domain)#auto-recovery reload-delay 240. Welcome to the Cisco Data Center section. So how does the Nexus 1000V form a single port channel across two separate switches not enabled for vPC? This is done with a simple configuration on the Nexus 1000V called vPC-HM. There is a major topology restriction with vPC when using the Nexus 2000 series Fabric Extender (FEX) in conjunction with the 5×00: you cannot configure a dual-layer vPC as shown in the diagram below. Whenever we configure the HSRP and VRRP in vPC domain , it behaves or operates in active-active mode, means all the ARP request and replay are handled by HSRP Active but for data traffic both Active and Standby acts as active-active . Version 7. 31. This section covers Cisco Data Center technologies found in small and large enterprise organizations around the globe. A connected non-Cisco device can also be represented in the topology. The command is supported starting from NX-OS version 5. A very imp0rnant feature for people who think configuring a vPC is a no-brainer, people like me. 255. 1. 10. This is familiar approach that Linux uses which loads what is installed and nothing else. Starting with the basics, and moving through to a deep dive, this real lab shows how Networ In VXLANv6, the platforms supported on spine are all Nexus 9000 Series and Nexus 3000 Series platforms. The same type of Cisco Nexus switches must be used for vPC pairing. Configure a vPC member. switch (config-cmap-qos) # match cos 4. 255. Assuming basic vPC peer-link is established, let’s take a look at the default configuration: Before we go into the configuration of vPC I wanted to mentioned that the Nexus 5600 series switch is a newer product in the Cisco Data Center portfolio. 11. 1. interface ethernet 1/5-6 no shutdown description ***vPC Member Port*** channel-group 30 mode active interface port-channel 30 no shutdown switchport switchport mode trunk switchport trunk allowed vlan add all vpc 30. interface port-channel2000 Verify that the Cisco Nexus series switch is reachable through the console or the management connection. As still now I was only configuring ,Please advise ,why do I need to unabe vPC on my ACE. This topology can also consist of hosts connected with virtual PortChannels to each Cisco Nexus 7000 Series Switch. There is no way to configure the Nexus 2000s except via the Nexus 5000. You need a port channel for the vPC peer link and the member ports. This gives the administrator the control to determine which switch will make decisions, lower is priority. The rule is simple: if the packet crosses the vPC peer link, it should not leave any port in a very vPC although that vPC doesn’t have the first VLAN. On each of the vPC+ peer link interfaces in interface configuration mode, enter the switchport mode fabricpath command. 11ac 1 802. Configure the vPC domain: vpc domain 1. A vPC domain is formed by both Nexus switches. With QoS, the settings should be the same on all switches in the datacenter. ip address 10. 5. 2/24 no shutdown Step-04 Verify keepalive connection using ping Nexus-02# ping 10. Now, you can check your snmp server to pool the information. Nexus configuration: The vPC feature must be configured. Create vPC Domain. For vPC peer 2, we need to add below configuration.

To verify that you have vPCs configured, run the following command on the device: show vpc brief. 168. We may see "vPC card type" Value mismatch on vpc peers. Due to other configuration limitations, all routing and HSRP is configured on the core. But there is some problem with bond configuration - it is working only on active/backup config. The domain-id must match on both peers. 20. Configure Spanning-tree 3. A vPC domain is similar in principle to a VTP domain in that devices in the same domain can share status information and configurations. After I went through the configuration of the vPC and appropriate ports, I brought the Nexus environment back online in a specific order to ensure spanning tree behaved correctly. Here I create a port-channel via LACP over ports 9/1 and 10/1. Livechat support so that you can gamble again as soon as possible in case of problems. All of these features are unique in Cisco Nexus 7000 and Cisco Nexus 5000. 7. cisco nexus configure vpc
