Entering rommon on a Cisco Switch from a Mac Laptop

Problem

I want to enter ROMmon on a Cisco software while connected via console. The break sequences I tried didn't work.

It didn't work for me.

On my Mac, holding the space bar for 15 seconds while booting the device didn't work, neither at 9600 nor 1200 baud. Ctrl-A + Ctrl-B nor backspace worked.

It did work for me:

Use Shift+CTRL+C during the first few seconds of booting the Cisco switch (in my case, a Cisco 4948).

I hope it helps.

Solution to quagga vtysh "Exiting: failed to connect to any daemons."

Description:
   When you run the command in the linux shell vtysh to connect to the quagga daemons (such as bgpd, ospfd, etc) returns  the following error "Exiting: failed to connect to any daemons"

Just like this:

alejandro @ miserver: ~ $ vtysh -d bgpd
Exiting: failed to connect to any daemons.

alejandro @ miserver: ~ $ vtysh
Exiting: failed to connect to any daemons.


Solution:
   The solution is to add the user that is executing vtysh to the quagga group. To do this edit the /etc/group file.
   After editing /etc/group should be something like:

quagga:x:1003:alejandro

You can specify multiple users doing:

quagga:x:1003:alejandro, john


   This is necessary because vtysh tries to connect to the daemons using UNIX domain sockets and not all users (for security reasons) have access to these sockets.

Another solution:
   Another solution might be during the compilation phase where you can specify the linux/unix group for sockets mentioned above. Example:

./configure --enable-vty-group = group


   Good luck, I hope this helped,

In case of emergency break glass. ¡Console cable inside!
