Chapter 36 Access Control • A non-administrator (username is something other than admin) is someone who can view but not configure Switch settings. Click Access Control from the navigation panel and then click Logins from this screen. Figure 178 Access Control: Logins The following table describes the labels in this screen. Table 120 Access Control: Logins LABEL DESCRIPTION Administrator This is the default administrator account with the "admin" user name. You cannot change the default administrator user name. Only the administrator has read/write access. Old Password Type the existing system password (1234 is the default password when shipped). New Password Enter your new system password. Retype to confirm Retype your new system password for confirmation Edit Logins You may configure passwords for up to four users. These users have read-only access. You can give users higher privileges via the CLI. For more information on assigning privileges see Chapter 45 on page 325. User Name Set a user name (up to 32 ASCII characters long). Password Enter your new system password. Retype to confirm Retype your new system password for confirmation Apply Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Cancel Click Cancel to begin configuring this screen afresh. GS-4012F/4024 User's Guide 295
