vCenter Appliance Network configuration change via command line.<\/span><\/a><\/o:p><\/span><\/p>\n

Most of the system configuration such as changing the hostname, IP, DNS..etc can be done using VAMI interface (https:\/\/vCenterIPorFQDN:5480<\/span><\/a>) however if you see the changes are not taking affect, e.g. changing the DNS IP then following command can be used.<\/o:p><\/span><\/p>\n

\u00b7         <\/span><\/span><\/span>Enable SSH using VAMI interface, select Access<\/span><\/b> tab, click Edit<\/span><\/b> and Enable SSH login<\/span><\/b>.<\/o:p><\/span><\/p>\n

\u00b7         <\/span><\/span><\/span>Take SSH session via putty to connect vCenter Appliance.<\/o:p><\/span><\/p>\n

\u00b7         <\/span><\/span><\/span>Use following command and change required configuration change.<\/o:p><\/span><\/p>\n
