You can connect to your device through a console session on the serial port, or through a Telnet or Secure Shell (SSH) connection to the management port or the inband port belonging to either the mgmt-vrf, default-vrf, or a user-defined vrf. You can use any account login present in the local device database or on a configured authentication, authorization, and accounting (AAA) server for authentication. For initial setup procedures, use the pre-configured administrative account that is part of the default device configuration.
The device must be physically connected to the network. If the device network interface is not configured or the device has been disconnected from the network, use a console session on the serial port.
Refer to the appropriate hardware guide for information on connecting through the serial port and establishing an Ethernet connection for a console session.
