The background on my situation is this - we are a disaster recovery shop that is trying to setup remote access to our internal servers via ip, utilizing Avocent KVM switches (keyboard, video, mouse) . The router is a Cisco 1720, KVM switches are Avocent DSR4020. The problem is when the router is connected to the external T1, after various time frames, any where from a few hours to a couple days, the DSR switches lose communication with the router. If we take away outside communication by removing the T1, the problem does not appear. Any help on this would be greatly appreciated. Thanks, Rick
From ur post there are several possiblities which can result in disconnections with ur KVM Switch.
First point to note here is the link between the KVM and the router,the second point would be the T1.
You need to find out where you are exactly experincing errors.
Once you loose the connectivitiy to the remote KVM u can confirm it by pinging the T1 interface to chek whether its still alive or not once u confirm that up u can check out for the port where u KVM switch is getting interfaced.
I did a clear of the counters, and checked the CRC count, which was 0 after about a 13 hour period (during which time we did experience multiple communication losses). Currently the interface to the kvm switch is a D-Link DES-1024d switch. COuld that switch have a buffer that is causing the problem? Thanks, Rick
