Well for the past few months I have had terrible bandwidth problems to one of our remote sites. We have a main campus and two remote campuses. Well each site has a CISCO 1720 router. The two remote sites connect back to the main site through these routers via a fractional T1 (frame relay) connection. Well I have noticed that when the connection drops to a crawl between the sites a simple reboot of one of the routers, doesn't matter which, usually fixes the problem. I will post whatever info I need, I just need some help figuring this one out. Thanks.
the fact that the problem solves itself when the router is reboot suggests that the fault might be local, rather than with the Frame Relay line. Can you post the output of 'show version', as wll as the output of 'show interface' (of the relevant frame relay interface) ?
From the show interface o/p i sense that you are having around 894K traffic ,can you justify the authenticity or the kinda traffic in your network ?
is it supposed to handle this much traffic or let me put it in the other way do u really have this much traffic in your network between your locations ?
i guess it mite be some unwanted worm or virus traffic if u dont have much traffic in place between your locations..
Also the droppage u meant did u try to ping it up when theres some issue and also it does show some input and CRC errors in ur serial link .suggest to get that checked tooo to avoid the probablities involved in troubleshooting your probs..
Well it does appear to slow down during the time a certain class comes to use one of the labs. They use some Internet based instructional software while they are in plus the normal faculty/staff checking email, surfing the web, using more online software. But, after rebooting the router everything works fine (even while they are working) until the next day. also when pinging the router or a any particular device on that network during peek hours I get no response or very slow like 400ms response time. But like I said a simple reboot and everything runs fine again.
