Dell EMC PowerFlex Appliance Administration Guide

Configuring the PowerFlex Gateway network interfaces

Use this procedure to configure your PowerFlex Gateway network interfaces.

1. Find the MAC addressees of the PowerFlex Gateway VM, by doing the following:
   1. Log in to vCenter.
   2. Right-click the PowerFlex Gateway VM and select Edit Settings.
   3. Select Network adapter 1 (<MGMT VLAN>) and record the MAC address.
   4. Repeat step for Network adapter 2 (<DATA1 VLAN>), Network adapter 3 (<DATA2 VLAN>), Network adapter 4 (<DATA3 VLAN> if required), and Network adapter 5 (<DATA4 VLAN> if required).
   5. Use the VMware virtual console to connect to the PowerFlex Gateway VM.
   6. At the command prompt, type:

      nmtui

   7. In the NetworkManager TUI screen, select Edit a connection.
   8. Under Ethernet, select Wired connection 1.
   9. Compare the MAC address listed on the Device line to the MAC addresses recorded above so that you know, which VLAN corresponds to Wired connection 1.
   10. Select Cancel.
   11. Repeat for Wired connection 2 and Wired connection 3 so that you have recorded which VLAN corresponds to each wired connection.
2. Using the nmtui command, configure the Wired connection corresponding to PowerFlex appliance management VLAN (<MGMT VLAN>).
   1. On the =ETHERNET line, select Show.
   2. Leave the Cloned MAC address line blank.
   3. Leave the MTU line blank.
   4. On the =IPv4 CONFIGURATION line, select Automatic and change to Manual then select Show.
   5. On the Addressees line, select Add and enter the IP address of this interface (<MGMT IP>).
   6. On the Gateway line, enter the default gateway (<DEF GW IP>).
   7. On the DNS Servers line, select Add and enter the DNS server IP address (<DNS IP>).
   8. On the Search domains line, select Add and enter the domain (<DOMAIN>). Do not select Never use this network for the default route.
   9. Select Ignore automatically obtained routes.
   10. Select Ignore automatically obtained DNS parameters.
   11. Select Require IPv4 addressing for this connection.
   12. On the =IPv6 CONFIGURATION line, select Automatic and change to Ignore.
   13. Select Automatically connect.
   14. Select Available to all users.
   15. To exit the screen, select OK.
3. Using the nmtui command, configure the Wired connection corresponding to PowerFlex Data 1 VLAN (<DATA1 VLAN>).
   1. On the =ETHERNET line, select Show.
   2. Leave the Cloned MAC address line blank.
   3. Set MTU to 9000.
   4. On the =IPv4 Configuration line, select Automatic and change to Manual then select Show.
   5. On the Addresses line, select Add and enter the IP address of this interface (<DATA1 IP>).
   6. Leave the Gateway line blank.
   7. Leave the DNS Servers line blank.
   8. Leave the Search domains line blank.
   9. Select Never use this network for the default route.
   10. Select Ignore automatically obtained routes.
   11. Select Ignore automatically obtained DNS parameters.
   12. Select Required IPv4 addressing for this connection.
   13. On the =IPv6 CONFIGURATION line, select Automatic and change to Ignore.
   14. Select Automatically connect.
   15. Select Available to all users.
   16. To exit, select OK.
4. Using the nmtui command, configure the Wired connection corresponding to the PowerFlex Data2 VLAN (<DATA2 VLAN>).
   1. On the =ETHERNET line, select Show.
   2. Leave the Cloned MAC address line blank.
   3. Set MTU to 9000.
   4. On the =IPv2 CONFIGURATION line, select Automatic and change to Manual then select Show.
   5. On the Addresses line, select Add and enter the IP address of this interface (<DATA2 IP>).
   6. Leave the Gateway line blank.
   7. Leave the DNS Servers line blank.
   8. Leave the Search domains line blank.
   9. Select Never use this network for the default route.
   10. Select Ignore automatically obtained routes.
   11. Select Ignore automatically obtained DNS parameters.
   12. Select Require IPv4 addressing for this connection.
   13. On the =IPv6 CONFIGURATION line, select Automatic and change to Ignore.
   14. Select Automatically connect.
   15. Select Available to all users.
   16. Select OK.
       NOTE If adding data5 and data6 VLANs for native asynchronous replication, repeat Step 3 and 4.
5. On the Ethernet screen, select Back.
6. On NetworkManager TUI screen, select Quit and then OK.
7. Review network configuration with the Linux ip addr command.
8. Verify that you can ping each of the network interfaces and the default gateway (<DEF GW IP>). Also, ping a PowerFlex node on all three networks.
