Speed Issues with Netgear GSM7248
Hi
My customers are complaining about speed issues on our network.
We have three Netgear GSM7248 switches linked with a single cat 5 cable as shown below.
This question has two parts really:
1. How do I configure a LAG using the web interface on these to double the speed of the uplink to each swicth, and maybe our servers too?
2. After inspecting each individual port on the swicthes they are set to AUTO. However a lot of the port speeds are set to 100mbs Half Duplex as opposed to the 1000mbs Full Duplex. Should I change these manually to 1000mbs?
Many Thanks

I trust you have spanning tree on otherwise you will definitely start getting speed issues with this arrangement due to broadcast loops. It doesnt hurt to set the port speeds so that there is no chance of any auto-negotiation conflicts. To configure a LAG you will need to choose one switch as the master with 2 LAGS and slave the others off it.

which version of switches are they?

It is V1
I think Spanning tree is enabled but its difficult to tell using the web interface

I'm running V 6.2.0.14. I have just downloaded V 6.3.3.7 and will install that.
In my current version I cant even find anything that says LAG let alone configure it but that will probably change when I update the firmware?
I have Proliant servers but I'm pretty sure I can fset that up, just havent had much exposure to switch management which is the main problem.
Thanks for your help with this guys all advice is greatly appreciated

This guide might help you set up the LAGs. http://kb.netgear.com/ci/fattach/get/69/1260525114/redirect/1
STP should be enabled by default.

Anglo, I found that guide myself but as you can see its very different from my web interface - Will that change with the upgraded firmware? Or are they using other software?
Thanks
Thanks
Arrgh! my switch has gone AWOL for web and telnet. As I am not on site I cannot comment at the moment. sorry.

Ive upgraded the firmware and it looks exactly the same. I cant see any LAG config options.
Any ideas guys?

I thought my switch was the same but unfortunately its not. Sometimes you get the advanced features not showing in the Web interace. From the manual it refers to the command line instructions.

Working now thanks
