<description><![CDATA[cmslick3 posted : Does the ASA use the DNS server to verify if the connection is up? Sounds like that's what is happening.<br><br>I'm no expert, but on all of our system we use 8.8.8.8 as primary DNS, and 4.2.2.4 as secondary. We do not have any kind of failover setup.]]></description>

<description><![CDATA[Paulg posted : Are you sure you changed the DNS server?  It sounds more like you changed the object being tracked by the SLA.<br><br>Mind sharing the exact changes made?]]></description>

<description><![CDATA[aight posted : I noticed last week that our ASA5510 was flapping (switching between the primary and secondary circuits) The only time I have ever seen this was due to a loose patch cable, interface going bad, power going bad, etc (usually layer 1 related issues). I opened up a TAC case w/ Cisco and their CCIE security god said that a public DNS (4.2.2.3) was reported to Cisco to be having issues earlier in the week.<br><br>He suggested that I change the DNS I was using on our firewall from 4.2.2.3 to  --> 8.8.8.8   I'm like WTF??? Are you serious??? <br><br>To my surprise, his suggestion worked!!!! Now, I'm more confused than ever ... I'm a freegin CCNP and I have never seen or heard of anything like this in all my Networking experience or studies.<br><br>Anyone ever seen this before?  I googled his solution and found nada.<br><small>--<br>You can say any foolish thing to a dog, and the dog will give you a look that says, 'My God, you're right! I never would've thought of that!'</small>]]></description>
