How to Rename Service Console

I was given task to build the system and then I started building it. It is not that I don’t know how to perform ESX build and believe me each hardware and every environment is different. Person has to go through these experiences as they explore the environment.

I build a new ESX box (DL 380) and then gave everything default. I choose a default VLAN for service console. When machine came back online it is not able to ping the default gateway. I started trouble shooting and starting to figure out how to make sure that if NIC are getting trunked on correct VLAN. To find out this one I used

“esxcfg-nics -l” . This will list us which NIC is up. Now the challenge was if the correct NIC is listening to the “Service Console”. To find out this one I used “esxcfg-vswitch -l” This will show the VLAN ID as well as which NIC is it is configured for.


Here you can see that “vmnic1” is “UP ” but “Service Console ” is configured for “vmnic0” . So here I have to basically swap the cable and bring “vmnic0” or change service console to listen to “vmnic1”. Easier would be swap the cable and then label the “service console” to listen to appropriate VLAN. Right now “Service Console ” is set to VLAN 0. To change the VLAN label use following “ esxcfg-vswitch –v <vlan id> -p “Service Conole” vSwitch0 ” (Command in the fist quotes should be run).

I did that and that fixed the network.
