    > In trying to get my Nexus switches working, I discovered a problem.  The colorized prompts on the Nexus switches use ANSI Escape codes.  This totally trips out rancid and causes it to miss commands.  I verified by turning off the colorization manually that is the issue.  I copied the cisco-nx and renamed it in my rancid.types.conf file and added
    > 
    > cisco-nx5600-9000;command;rancid::RunCommand;no term color
    > 
    > right before the line
    > 
    > cisco-nx5600-9000;command;rancid::RunCommand;term no monitor

    hold on while i curse for 20 minutes.  seriously cisco, what is the utility
    of this.
    
    can you disable it by default in the config?  Maybe setting a non-color-
    supporting TERM would work?
    

It’s disabled by default, but, I do believe rancid should be able to work through this.  Btw, I’m running 3.6.2.  It’s also an easy to fix on a per-session basis by executing the “no term color” command, which I tried.  I suspect the changed prompt threw off rancid since it didn’t match what it saw before.  The testing account I am using happens to have it turned on all the time because humans use it and it’s useful.
