Once you created a join token, you can modify only the tags that are associated with the token. You cannot modify the name or description of the token.
To edit a join token, complete the following:
Log in to the Cloud Services Portal.
Go to the Manage > Infrastructure > Join Tokens tab.
On the Join Tokens page, select the check box of the join token you want to configure, and then click Edit.
In the Edit <Join Token> dialog, edit the tags you have configured. You cannot modify the name or description of the join token. For information about using tags, see Managing Tags.
