Networking Problems

You may also experience a condition that causes you to lose all or part of your networking configuration or where a configuration change causes the Service Console to lose network connectivity. If this happens, you will not be able to connect to the host by any remote method, including the VI Client or SSH. Your only recourse will be to rebuild or fix the network configuration from the local Service Console using the esxcfg- command-line utilities. Here are some of the commands that you can use to configure networking from the ESX CLI:

• esxcfg-nics This command displays a list of physical network adapters along with information about the driver, PCI device, and link state of each NIC. You can also use this command to control a physical network adapter's speed and duplexing. Type ¬esxcfg-nics -l to display NIC information and esxcfg-nics -h to display available options for this command. Here are some examples:
  
  • Set the speed and duplex of a NIC (vmnic2) to 100/Full:
    esxcfg-nics -s 100 -d full vmnic2
  • Set the speed and duplex of a NIC (vmnic2) to autonegotiate:
    esxcfg-nics -a vmnic2
• esxcfg-vswif Creates and updates Service Console network settings, including IP address and port group. Type esxcfg-vswif -l to display current settings and esxcfg-vswif -h to display all available options for changing settings. Here are some examples:
  
  • Change your Service Console (vswif0) IP and subnet mask:
    esxcfg-vswif -i 172.20.20.5 -n 255.255.255.0 vswif0
  • Add a Service Console (vswif0):
    esxcfg-vswif -a vswif0 -p "Service Console"
    ⇒ -i 172.20.20.40 -n 255.255.255.0
• esxcfg-vswitch Creates and updates VM (vSwitch) network settings, including uplink NICs, port groups, and VLAN IDs. Type esxcfg-vswitch -l to display current vSwitch configurations and esxcfg-vswitch -h to display all available options for changing settings. Here are some examples:
  
  • Add a physical NIC (vmnic2) to a vSwitch (vSwitch1):
    esxcfg-vswitch -L vmnic2 vswitch1
  • Remove a pNIC (vmnic3) from a vSwitch (vSwitch0):
    esxcfg-vswitch -U vmnic3 vswitch0
  • Create a port group (VM Network3) on a vSwitch (vSwitch1):
    esxcfg-vswitch -A "VM Network 3" vSwitch1
  • Assign a VLAN ID (3) to a port group (VM Network 3) on a vSwitch (vSwitch1):
    esxcfg-vswitch -v 3 -p "VM Network 3" vSwitch1
• esxcfg-route Sets or retrieves the default VMkernel gateway route. Type esxcfg-route -l to display current routes and esxcfg-route -hto display all available options for changing settings. Here are some examples:
  
  • Set the VMkernel default gateway route:
    esxcfg-route 172.20.20.1
  • Add a route to the VMkernel:
    esxcfg-route -a default 255.255.255.0 172.20.20.1
• esxcfg-vmknic Creates and updates VMkernel TCP/IP settings for VMotion, NAS, and iSCSI. Type esxcfg-vmknic -l to display VMkernel NICs and esxcfg-vmknic -h to display all available options for changing settings. Here is an example:
  
  • Add a VMkernel NIC and set the IP and subnet mask:
    esxcfg-vmknic -a "VM Kernel" -i 172.20.20.19 -n 255.255.255.0

In addition, you can restart your Service Console network by using the command service network restart.

Other Problems

Sometimes just restarting some of the ESX services will resolve problems and not affect the VMs running on the host. Two services that can be restarted and often fix many problems are the hostd service and the vpxa service. The hostd service runs in the Service Console and is responsible for managing most of the operations on the ESX host. To restart the hostd service, log on to the Service Console and type service mgmt-vmware restart.

The vpxa service is the management agent that handles communication between the ESXhost and its clients, including the vCenter Server and anyone who connects to the host using the VI Client. If you experience problems with vCenter Server showing a host as ¬disconnected, not showing current information, or any other strange problems involving vCenter Server and a host, restarting this service may resolve it. To restart the vpxa service, log on to the Service Console and type service vmware-vpxa restart. It is recommended to try to restart these two services when you are experiencing problems because this will often resolve many problems.
