RE: Is Cisco equpiment de facto for you?

Cisco IOS has a similar feature.

reload in 5 make changes verify things are working reload cancel

There seems to be a better way to do it in IOS that will not reload the router: http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtrollbk.html I haven't tried it since all my gear has OOB serial mgmt but it appears to let you rollback a config after a set time without a reboot. It still doesn't seem to be as nice as JUNOS rollback.
