Thank you in advance for all your help.\n\nI know this may be a pretty simple question but none-the-less I am a\nnovice. The company I work for had recently been experiencing\nintermittent connectivity problems with remote sites via T1\nconnections. The links had been operating normally and then without\nany configuration changes began faltering. A simple reboot of the\ncentral router solved the problems. Basically what I am asking is, is\npower-cycling a necessary maintenance procedure for router and/or\nother Cisco equipment such as switches. I am asking specifically\nabout the 3600 and 2600 series of routers. I have never heard of it\nbeing so but like I said I am a beginner.\n\nThanks again for any help you can offer.
