Logging in through the console port

When a device becomes a stack member in a traditional stack, it establishes a remote connection to a virtual console port on the active controller. Input and output are relayed between the physical console port on the stack member and the virtual console port on the active controller. Because each stack member connects to an independent virtual console port on the active controller, the console ports on multiple stack units may be used simultaneously.

When a stack unit establishes communication with the active controller, it also establishes a remote console session to the active controller. In a normally functioning traditional stack, a console cable may be connected to any of the stack units and provide access to the same commands on the active controller.

To establish a remote console session, enter the rconsole command followed by the stack unit ID.

device# rconsole 1

You can terminate a session between stack members in any of these ways:

Enter the logout command at any level.
Enter the exit command from the User EXEC level.

NOTE

For rconsole connections from stack units to the active controller, the escape sequence and other methods of terminating the session are not available.

NOTE

Error messages that are generated during a reload of the active controller do not appear on rconsole connections from stack units to the active controller. To see these error messages, you must connect a console cable to the active controller itself.

The following example shows how to establish a remote console session to a stack member and obtain status information. Notice that the show stack command on the stack members displays different information from what is shown when the show stack command is entered on the active controller.

A remote console session is established with stack unit 2 in the following example.

device# rconsole 2
Connecting to unit 2... (Press Ctrl-O X to exit)
rconsole-2@device# show stack
ID   Type          Role      Mac Address      Prio  State    Comment  
2 D  ICX7750-48XGF standby   cc4e.246d.8d800  0     local    Ready
rconsole-2@device# exit
rconsole-2@device> exit
Disconnected.  Returning to local session...
