Details

You may experience the following symptoms:

  • The Service Console loses connectivity
  • Due to misconfiguration of service console network connection fails
  • An additional NIC is added to ESX host

Solution

To delete and recreate a virtual switch and Service Console with the command line:
 
Note: On your system the vswif, vmnic, vSwitch numbers and network settings are different. 
  1. Run the following command to list the name of the vswif adapter:

    esxcfg-vswif -l

  2. Run the following command to delete the vswif adapter:

    esxcfg-vswif --del vswif0

  3. Run the following command to list the name of the vSwitch:

    esxcfg-vswitch -l

  4. Run the following command to delete the vSwitch:

    esxcfg-vswitch -d vSwitch0

  5. Run the following command to create the vSwitch:

    esxcfg-vswitch -a vSwitch0

  6. Run the following commands to create default port groups for vSwitch:

    esxcfg-vswitch -A "VM Network" vSwitch0
    esxcfg-vswitch -A "Service Console" vSwitch0

  7. Run the following command to create the vswif adapter:

    esxcfg-vswif --add --portgroup "Service Console" --ip=nnn.nnn.nnn.nnn --netmask=255.255.255.0 vswif0 

  8. Run the following command to verify that the settings in the network file are correct:

    cat /etc/sysconfig/network

    NETWORKING=yes
    GATEWAYDEV=vswif0
    HOSTNAME=host.domain.com
    GATEWAY=nnn.nnn.nnn.nnn

  9. Run the following commands to list all of the network adapters and associate a vmnic which has a link status of up:

    esxcfg-nics -l
    esxcfg-vswitch -L vmnic1 vSwitch0

  10. Run the following command to verify that the vmnic is associated with the vSwitch:

    esxcfg-vswitch -l

  11. Ping an IP address to check for network connectivity. If the ping fails remove the previous vmnic from the vSwitch and try another adapter that has a link status of up.

    esxcfg-vswitch -U vmnic1 vSwitch0
    esxcfg-vswitch -L vmnic2 vSwitch0

  12. Run the following command to change the vlan ID of a vSwitch

    [root@server root]# esxcfg-vswitch -p "VM Network 1" -v 10 vSwitch0


  13. If you make any manual changes to /etc/sysconfig/network, run the following command to restart the network service:

    service network restart
