Internet speed in L2 switchs

[Elfrido]

Hi all 

I am facing a weird issue recently I have replaced my 2960 switchs with a new model 9200 switchs

after that, the internet speed becomes slower than before.

Please, does anyone have any idea?

i would check below :

1. port-negotiation issue (may be)

2. speed mis-match

3. any interface errors (inside and outside where connected)

4. check any logs

post interface config here (Old switch and new switch)

Hello,

it is difficult to analyze that without knowing what the rest of your topology looks like, and where the 9200 switches are located. Do you have a diagram of your topology ?

One of the things that I would look for is the possibility of duplex mismatch - it might be between a connected host and the new switch, or between the new switch and its uplink peer.

It would help us if we had more detail about how the new switch is configured, and how the switch that it replaced was configured.
