To the physical switch, attach only the network cable used for the service console.<br /><br /> 2. List all of the network adapters from the ESX Server service console and locate the name of the vmnic# that has a link status of up.<br /><br /> esxcfg-nics –l<br /><br /> 3. If vmnic0 has a link status of up, stop now. Otherwise, remove vmnic0 from vSwitch0.<br /><br /> esxcfg-vswitch -U vmnic0 vSwitch0<br /><br /> 4. Associate the vmnic# that has a link status of up from step 2.<br /><br /> esxcfg-vswitch -L vmnic# vSwitch0<br /><br />Use the following commands to determine where the ESX Server service console portgroup is (if you are doing a repair after changing physical NICs or similar activity, for example):<br /><br /> * esxcfg-nics -l<br /> Determines which NICs are link up esxcfg-vswif -l to ensure Service Console is the port group, and the settings are correct.<br /><br /> * esxcfg-vswitch -l<br /> Shows which vSwitch the service console port group is in.<br /><br /> * esxcfg-vswitch -L <lowest vmnic from link up listing> <vSwitch w/Service Console port group><br /> Links the vmnic and service console together.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3189102510981858863-5880053762403927455?l=vsphere-tips.blogspot.com' alt='' /></div>Jainhttp://www.blogger.com/profile/03086193167071815021noreply@blogger.com0tag:blogger.com,1999:blog-3189102510981858863.post-350267905919684292009-10-28T04:01:00.000-07:002009-11-03T19:51:44.569-08:001.
