After that I changed the Duplex parameter on NIC's Service console, I am not able to connect the ESX host

Hi all

Please help solve my problem.

After that I changed the Duplex parameter on NIC's Service console, I am unable to connect the ESX host. How can I reset the 100 MB NETWORK card duplex. Can someone help me please.

Concerning

Vijay

Hello

As the bulb you have two problems that are not related.

(1) duplex setting, your switch and NIC must match. If one is assigned to auto-negotiation, then the other must be set to auto-negotiation. Personally, I tend to let auto-negotiation unless there is an absolute reason to spend. If you then turn on the both sides of the interface, the switch port and esxcfg-NICS allows you to change the duplex, etc.

(2) passwords for root are not related to the network unless you have also run esxcfg-auth authentication remote.  The only time I saw what you have here is when the system is configured to try to authenticate remote and not locally.

The two problems are fixable by booting into single-user mode, set the duplex and reset the password.
