Standard Credentials for Initial Access For the vast majority of physical Cisco Catalyst switches running IOS or IOS-XE, the default username is typically blank, and the default password is also blank during the initial setup phase. From ROMMON, the configuration register can be changed to bypass the startup configuration, allowing the device to load without the saved credentials.

The initial access is granted through the Meraki Dashboard, which requires an administrator email and password created during the organization's setup. However, in some older models or specific software versions, the username "admin" might be used with a blank password or a temporary default password printed on the device label.
Generally, this involves connecting to the device via console and booting into ROMMON mode by interrupting the boot process. When a network administrator unboxes a new Catalyst or Meraki switch, the immediate priority is often establishing a console connection to configure basic settings.
