I am also facing somewhat similar issue with Cisco switches. <div class="gmail_quote">On Mon, Jun 27, 2011 at 9:31 PM, Bailey, Damian S. <<a href="mailto:baileyds@lcps.k12.va.us">baileyds@lcps.k12.va.us</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div lang="EN-US" link="blue" vlink="purple"> <div> We’re new to using Nagios but I’ve grown to love it! In using the product to perform host checks on our Cisco switches, I find that they “randomly” will fail, then recover almost immediately. I think the host checks use ping to verify that the switches are active. Is there something I am likely doing wrong, or should I look at our network as a possible cause? Our network itself isn’t perfect…but I don’t want to go looking for problems if it’s a nagios issue. Thanks for any help. I’ll be glad to provide more info if needed.
