What's the best way to configure our Netgear GSM7212 L2 Managed Switch ?

We have a switch at our datacentre to switch traffic based on IP address.  We have been noticing lately that the connections seem to be slower when accessing any of the resources and think this is due to the fact that there may be configuration problems on the switch.

What is the best way to configure the switch so that different ports only deal with traffic for the 1 IP address ?  For example, say our switch has an IP address of 80.80.80.80 and then there is a router connected to port 1 which has an IP address of 80.80.80.81.  How should this be configured ?

Many thanks in advance

A L2 switch typically knows nothing about IP addresses, as L2 is MAC layer, in your case Ethernet.  Unless you are doing VLAN's or have multiple switches interconnected typically you don't need to configure a L2 switch.

Can you quantify "slower?"

I would verify that you have good cabling, to get Gigabit throughput you need CAT5e or CAT6 cables, and that the NIC and switch are negotiating 1000 Mbps full duplex.

Can you post the configuration?
agree with giltjr...

and if we are dealing with netgear, please take check if latest firmware available....

Hi all and thanks for your replies,

Just to try and set the scene here, the switch is in a datacentre that we hire a rack in.  The switch is connected to the hosting companies internal network which then goes out to the internet.  Also connected to the switch are four routers that are for 4 different clients.  Of these clients some of them have access to their data via a VPN and others use Citrix but the main thing is that all clients have been complaining that things are slower.  With the users on the VPN the data is taking longer to download and with the Citrix users they keep being disconnected.

Basically, I want to know if there is anything that can be done on the router to speed things up.

Thanks again for your help.

P.S  I 'm not sure how to get the configuration but I will post it as soon as I can figure it out
have you tried to update firmware on the switch?
do you have any vlans configured?
Hi again,

No we don't have any vLan's configured.  I'm not 100% sure of these work on this particular switch.

The router is quite new so didn't think i'd need to update the firmware just yet.  Do you think we should update it anyway ?
hm, I mean firmware on netgear switch..
Sorry, I meant the switch
I have not looked at the doc for the GSM7212, but as it is managed I am assuming that it has SNMP.  

What I would suggest is, assuming you are not, is setting something up like MRTG to monitor the bandwidth utilization on all ports on the switch.

The next thing is to look at CPU and memory utilization on the servers.  As we know nothing about the enviroment, it is possible that the servers could be maxed out and causing the performance issues.
Hi giltjr,

Yes the switch has SNMP.  At present I am not using any monitoring tools to monitor the switch.  I am currently installing MRTG and will try and use that to help identify the problem
