How to test network speeds?
I have a core switch 3 com model :
3Com Switch 5500G-EI 48-Port Software Version 3Com OS V3.03.02s56
It has connected to it via UTP two 3Com Baseline Switch 2948 Plus's
These are connected to the core switch via two UTP cables trunked for extra bandwidth....I've had nothing but problems with clients doing GPO updates connected to the 2948's so decided to do some testing with a spare Allied Telesis switch.
I get exactly the same issues with the AT switch as I do the 3 com switch.
See attached screenshot....
If I connect the clients direct to the core switch (5500G) then all works fine every time.
See attached screenshot
I thouhgt initially the issue was with the 3 com edge switches but since the AT edge switch does the same now I'm not convinced.
My next trial is going to be to connect the AT switch to the core not using copper but using a fibre lead and SPF modules.
If anyone else can offer any suggestions...
How could I test the network speeds from the clients as they are now going through the AT switch before I uplink it with copper?
