Stop extended ping or traceroute command

Every introductory Cisco course tells you that you can stop any IOS command (for example, ping or traceroute) with the Ctrl/^ (also written as ^^ or Ctrl-Shift-6) escape character. What they usually forget to tell you is how to do that on non-US-ASCII keyboards or with telnet programs that do not want to recognize weird control characters.

The trick is simple - if you cannot generate ^^ (ASCII code 30), change the escape character. You can change it for the current session with the terminal escape-character char exec-level command or permanently with the escape-character char line configuration command. For example, to set the escape character for the current session to ctrl-C, use terminal escape-character 3 command.

    Hello,

    I have a Cisco 2511-RJ and couple of routers&switches bundled for CCIE Lab. All works well except when I want to switch connections on the access-server. I use CTRL-SHIFT-6, x but no luck.

    I tried an update for the 2511 to 12.3(26). Also I configured on it
    terminal escape-character 3 then I use "for switching between sessions" CTRL-C, x. But again, no luck.

    Any suggestion?

      Have you ever thought about (for example) "terminal escape-character 4"?

    A bit late to the answer, but I have a fix for your SecureCRT issue when using Windows hotkey options. You can map any unused key combination to send "\003" which is the same as "CTR+SHFT+6" in SecureCRT. I used "CTR+SHFT+5" and it works perfectly.
    To do so:
    1. Session and/or Global options
    2. Terminal > Emulation > Mapped Keys
    3. Click "Map a key..."
    4. Press your key combination, ie "CTR+SHFT+5"
    5. Leave "Send String" option in drop down box.
    6. Enter "\003" without the quotes and click "OK"
    7. Close/reopen SecureCRT.
    8. Enjoy.

    Thank you Ted! Mapping "\003" to a key combo in SecureCRT works like a charm in ASR9K
