Good morning,
Over the past few weeks, we've been having some intermittent problems with our internet connection. At one time I noticed a lot of lost carriers on our PIX, and since a reboot of the PIX last week, I haven't seen any additional lost carriers, but what I am seeing is a lot of 'deferred', and some 'interface resets'. Any advice would be appreciated. Below are the captures for a 'show interface' command on both the router, and the firewall.
I think the firewall capture is fairly 'normal', but maybe I'm missing something.
Please note that both units were rebooted about 7-10 days ago, so all counts fall within that timeframe.
Thanks in advance for any advice/assistance!
