Restore Network Configuration of vSwitch

[AssistenzaNS]

Good morning,

After changing some settings on a server with a vSwitch, we have problems of connectivity and we wanted

to bring the vSwitch to the default settings.

The server has ESXI 4.0.

Failing to reach the remote server we can only use the command line console

This is possible ?

Thank you

hope below steps can help you

Recovering From Network Configuration Errors using the  Direct Console User Interface (DCUI).

vSphere 5.1 and later allows you to connect directly to a host to fix distributed switch properties or other networking misconfigurations using the Direct Console User Interface (DCUI).

Notes:

• Recovery is not supported on stateless ESXi instances.
• The Management Network must be configured on a distributed switch. This is the only way you can fix distributed switch configuration errors using the DCUI.

To restore VDS from DCUI:

1. Connect to the DCUI.
2. From the Network Restore Options menu, select Restore vDS.
3. Type the correct values for VLAN uplink and blocked properties, where appropriate.
4. Press Enter.

The DCUI clones a host local port from the existing misconfigured port and applies the values you provided for VLAN and Blocked. The DCUI changes the Management Network to use the new host local port to restore connectivity to vCenter Server. vCenter Server picks up the new host local port and updates its database with the new information. vCenter Server creates a standalone port that is connected to the Management Network.

Hi,

no only way u could login is from ilo command line would not work if it is not pingable.

As been stated , its esxi 4.0 login to console from ilo/idrac

1) check the network settings , check vmnic if it is connected to one which is active?

2) check vlan id is getting detected

if above deoesn't work , restore network.
