1. Configure Management Switches: NetApp HCI with RHV
Cisco Nexus 3048 switches are used in this deployment procedure to provide 1Gbps connectivity for in and out-of-band management of the compute and storage nodes. These steps begin after the switches have been racked, powered, and put through the initial setup process. To configure the switches to provide management connectivity to the infrastructure, complete the following steps:
Enable Advanced Features for Cisco Nexus
Run the following commands on each Cisco Nexus 3048 switch to configure advanced features:
-
Enter configuration mode.
Switch-01# configure terminal
-
Enable VLAN functionality.
Switch-01(config)# feature interface-vlan
-
Enable LACP.
Switch-01(config)# feature lacp
-
Enable virtual port channels (vPCs).
Switch-01(config)# feature vpc
-
Set the global port-channel load-balancing configuration.
Switch-01(config)# port-channel load-balance src-dst ip-l4port
-
Perform global spanning-tree configuration.
Switch-01(config)# spanning-tree port type network default Switch-01(config)# spanning-tree port type edge bpduguard default
Configure Ports on the Switch for In-Band Management
-
Run the following commands to create VLANs for management purposes:
Switch-01(config)# vlan 2 Switch-01(config-vlan)# Name Native_VLAN Switch-01(config-vlan)# vlan 16 Switch-01(config-vlan)# Name OOB_Network Switch-01(config-vlan)# vlan 1172 Switch-01(config-vlan)# Name MGMT_Network Switch-01(config-vlan)# exit
-
Configure the ports ETH1/29-32 as VLAN trunk ports that connect to management interfaces on each HCI storage node.
Switch-01(config)# int eth 1/29 Switch-01(config-if)# description HCI-STG-01 PortA Switch-01(config-if)# switchport mode trunk Switch-01(config-if)# switchport trunk native vlan 2 Switch-01(config-if)# switchport trunk allowed vlan 1172 Switch-01(config-if)# spanning tree port type edge trunk Switch-01(config-if)# int eth 1/30 Switch-01(config-if)# description HCI-STG-02 PortA Switch-01(config-if)# switchport mode trunk Switch-01(config-if)# switchport trunk native vlan 2 Switch-01(config-if)# switchport trunk allowed vlan 1172 Switch-01(config-if)# spanning tree port type edge trunk Switch-01(config-if)# int eth 1/31 Switch-01(config-if)# description HCI-STG-03 PortA Switch-01(config-if)# switchport mode trunk Switch-01(config-if)# switchport trunk native vlan 2 Switch-01(config-if)# switchport trunk allowed vlan 1172 Switch-01(config-if)# spanning tree port type edge trunk Switch-01(config-if)# int eth 1/32 Switch-01(config-if)# description HCI-STG-04 PortA Switch-01(config-if)# switchport mode trunk Switch-01(config-if)# switchport trunk native vlan 2 Switch-01(config-if)# switchport trunk allowed vlan 1172 Switch-01(config-if)# spanning tree port type edge trunk Switch-01(config-if)# exit
Configure Ports on the Switch for Out-of-Band Management
Run the following commands to configure the ports for cabling the IPMI interfaces on each HCI node.
Switch-01(config)# int eth 1/13 Switch-01(config-if)# description HCI-CMP-01 IPMI Switch-01(config-if)# switchport mode access Switch-01(config-if)# switchport access vlan 16 Switch-01(config-if)# spanning-tree port type edge Switch-01(config-if)# int eth 1/14 Switch-01(config-if)# description HCI-STG-01 IPMI Switch-01(config-if)# switchport mode access Switch-01(config-if)# switchport access vlan 16 Switch-01(config-if)# spanning-tree port type edge Switch-01(config-if)# int eth 1/15 Switch-01(config-if)# description HCI-STG-03 IPMI Switch-01(config-if)# switchport mode access Switch-01(config-if)# switchport access vlan 16 Switch-01(config-if)# spanning-tree port type edge Switch-01(config-if)# exit
In the validated configuration, we cabled odd-node IPMI interfaces to Switch-01 and even-node IPMI interfaces to Switch-02. |
Create a vPC Domain to Ensure Fault Tolerance
-
Activate the ports used for the vPC peer-link between the two switches.
Switch-01(config)# int eth 1/1 Switch-01(config-if)# description vPC peer-link Switch-02 1/1 Switch-01(config-if)# int eth 1/2 Switch-01(config-if)# description vPC peer-link Switch-02 1/2 Switch-01(config-if)# exit
-
Perform the vPC global configuration.
Switch-01(config)# vpc domain 1 Switch-01(config-vpc-domain)# role priority 10 Switch-01(config-vpc-domain)# peer-keepalive destination <switch-02_mgmt_address> source <switch-01_mgmt_address> vrf managment Switch-01(config-vpc-domain)# peer-gateway Switch-01(config-vpc-domain)# auto recovery Switch-01(config-vpc-domain)# ip arp synchronize Switch-01(config-vpc-domain)# int eth 1/1-2 Switch-01(config-vpc-domain)# channel-group 10 mode active Switch-01(config-vpc-domain)# int Po10 Switch-01(config-if)# description vPC peer-link Switch-01(config-if)# switchport mode trunk Switch-01(config-if)# switchport trunk native vlan 2 Switch-01(config-if)# switchport trunk allowed vlan 16, 1172 Switch-01(config-if)# spanning-tree port type network Switch-01(config-if)# vpc peer-link Switch-01(config-if)# exit
