You must provide valid settings for the port group manually. You have performed more than one configuration step and you do not have a backup file You can also restore the configuration for the entire switch, including the port group, from a backup file for the switch. Right-click the port group, click Restore Configuration, and select Restore configuration from a file. You can restore the configuration of the port group by using the backup file. You have backed up a valid configuration of the port group At installation time, the ESXi firewall is configured to block incoming and outgoing traffic, except traffic for services that are enabled. ESXi includes a firewall that is enabled by default. Right-click the port group, click Restore Configuration, and select Restore to previous configuration. The vSphere Client and the VMware Host Client allow you to open and close firewall ports for each service or to allow traffic from selected IP addresses. You can roll the configuration of the port group back one step. The Figure 1 below shows two ESXi hosts with four Ethernet network adapters each. You have altered the port group configuration only once In the vSphere Client, configure the distributed port group for the management network with correct settings. The DCUI changes the VMkernel adapter for the management network to use the new host local port to restore connectivity toĪfter the host re-connects to vCenter Server, the vSphere Client displays a warning that some hosts on the switch have different networking configuration from the configuration stored in vSphere distributed switch. The kernel value parameters aren't saved with these commands, and are reset to the default values on system reboot, thus make sure to place the commands on a system startup script such as /etc/rc.local.The DCUI creates a local ephemeral port and applies the VLAN and uplink configuration to the port. Increase the range of ephemeral ports by setting ip_local_port_range kernel value on /proc/sys/net/ipv4/ip_local_port_range, using the command echo "32768 65535" > /proc/sys/net/ipv4/ip_local_port_range, this will set the port range from 32768 to 65535. Increase the range of ephemeral ports by setting the dynamicportrange to an higher value through the command netsh int ipv4 set dynamicportrange tcp start=32767 num=65535, this will set the port range from 32768 to 65535. Edit a Standard Switch Port Group By using the vSphere Client, you can edit the name and VLAN ID of a standard switch port group, and override networking policies at the port group level. This will set the port range from 1024 to 32768. Add a Virtual Machine Port Group Add VM port groups on a vSphere Standard Switch to provide connectivity and common network configuration for virtual machines. Increase the range of ephemeral ports by setting the MaxUserPort TCP/IP parameter to an higher value (like 32768), on the windows registry key HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, as a DWORD value. You add an Ephemeral Port Group the same way you’d add any other Distributed Port Group. What does that mean It’s a DVS Port Group that can be modified when vCenter is offline. Instructions for the correspondent operating system. An Ephemeral Distributed Port Group is a special Port Group that does not adhere to the same binding restrictions.
