I'm considering switching from the Catalyst 6500 switches we use on our campus network to Catalyst 3750-E switches. But, I'm not sure if its a good move. The 3750 switches appear to be able to handle our traffic levels. We use them at the access layer of our network. The way we use the 6500's has changed. Our bandwidth requirements between devices directly connected to the 6500's has reduced. So the high backplane bandwidth of the 6500 seems no longer needed. We basically use them now to aggregate the access layer connections (SX and LH/LX connections) and provide 10Gigabit links between sections of the campus. Both of which we could do on the 3750's now. We don't really use the blade feature of the 6500's either. We do plan to use virtualization in our network. But the 3750's appear to hande that as well. I could go to the Catalyst 4500's but again, the blade feature really doesn't benefit us. Opinions welcome.
