Interesting thought. The 2801 did have some sort of notice about a duplicate DHCP entry or some such thing....unfortunately, everything was happening so fast, and there is that need to JUST FIX IT,that there isn't a lot of time to write stuff down or gather relevant stats. <br>
<br>Looks like I will be doing further research!!<br><br>Todd<br><br>I think it might be time to set up my cisco gear so it logs relevant happenings to a syslogger on one of my linux/doze boxes.<br><br><div class="gmail_quote">

One-way audio is almost always a routing issue, my guess is that you<br>
have a duplicate route to a subnet or a duplicate IP taking over a key<br>
layer-3 routed interface.<br>
