Slow Network.

[kalpeshcisco]

Hi all,

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.

thanks,

abc.

Hi,

After setting both sides to auto and changing the cables, there are no CRC errors now. Seems the network response was slow due to bad cables. The Switch was showing input/output packets during business hours. And there is considerable difference than before.
