That is the really neat feature about the rollback command. Like I said before it has saved me more ways the one. :-) -----Original Message----- From: Owen DeLong [mailto:o...@delong.com] Sent: Thursday, January 13, 2011 2:59 PM To: Jack Bates Cc: Michael Ruiz; nanog@nanog.org Subject: Re: Is Cisco equpiment de facto for you?

With JunOS, I can have the changes I made running for days, but, when some problem is later discovered I can still rollback to the previous (or several revisions back). I can easily compare the current config to several previous revisions, etc. Additionally, with JunOS I can make all my changes, verify them syntactically, compare the changes made to the previous configuration all without having the changes take effect during the process. Then, when I'm satisfied I have it right, I commit the configuration. If you've ever had to play the IOS ACL rotation game, you know how wonderful this feature is. Cisco's half-hearted attempt to play catch-up here is woefully inadequate. Owen
