Cisco Command Christmas Calendar #9: Ctrl-Shift-6

Okay, so this one is not really a command. It's a shortcut. The Ctrl-Shift-6 has a couple of great use cases. First, it can be used to interrupt an IOS process such as ping/traceroute or even the DNS lookup process from the previous post. Example:

Translating "showrun"...domain server ( [Ctrl-Shift-6]

% Name lookup aborted

% Bad IP address or host name

% Unknown command or computer name, or unable to find computer address

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
.. [Ctrl-Shift-6]
Success rate is 0 percent (0/2)

Note that only two ping packets were sent before the Ctrl-Shift-6 was issued.

The second use case of the Ctrl-Shift-6 shortcut is to suspend a Telnet session. If you press Ctrl-Shift-6 and then x, the device will suspend the current Telnet connection and return to the system command prompt.

Trying ... Open

R10# [Ctrl-Shift-6, x]


Now if you simply hit Enter, the device will resume the Telnet connection.

R2# [Enter]
[Resuming connection 1 to ... ]
