This is just an general question. We have two subnets on our network. Both these networks are routed. We have Cisco 1721 Router. It has only one Ethernet Module. We cannot user another. It is the gateway for subnet1 and subnet2. subnet2 gateway is defined as secondary. We have several cisco 2950 series switches. All our server are in subnet1.
Now to say, anyone in subnet2 trying to access resourses like servers, network printers which are in subnet1, the responce time is very slow. Like you click on a file to save / print, it takes long time. Whereas users on subnet1 have no problems (since all resources are on same subnet).
I guess we need to either upgrade the router or connect a layer 3 switch.
Is the network on subnet2 experiencing slow response since its gateway is defines as secondary ? I mean to ask, does this effect in any such way ?
Please give some suggestions. Hope am clear.
Setting both sides to auto is worth a try, but if that doesn't help you need to try another switch port. If still seeing errors the next step would be to swap out the router.
Try setting both sides to autonegotiate if you haven't already, to clear up the CRC/input errors/etc. The traffic is routed through that Ethernet interface, so if it's taking errors you are certain to see some degredation.
I've had problems with 2950s being hardcoded recently, as well as the devices on the opposite end being hardcoded. Same symptoms as yourself.
Look at the device interface settings on whatever is connected to the other end . That end must be 100/full also , you appear to be taking a lot of crc's . The interface is not overloaded , the 5 minute input and output rate is less than 1 meg per sec . Suspect a link mismatch .
