Use normal trunk port or use channel for connection access switch

Good afternoon people,

 

I have a question,

What will be the best option, I have backbone 4705E2x,  2x 3750X core switch (stacked) and will attach around 35 access switches (2960) to it for some production area.

 

I want to connect them as channel so I have a uplink of 2GB, when I would make just a trunk on both GB ports, SPT will automatically block one and I will have a uplink of only 1 GB.

 

What is the best option ?

 

See PDF file for drawing

 

Thanks guys!

Yes, use a channel! Why wasting half of your uplink-bandwidth when you don't have to. Ok, also without a channel you could utilize both links with different spanning-tree costs for different links. But a channel should be better in every way.

If you are going to do two links I would put them in an etherchannel. You will have bandwidth and failover capabilities.

In your picture it seems that

In your picture it seems that both 4k are only connected to one core-switch each. Make sure that you connect one channel-link to the first stack-member and the other channel-link to the other stack-member. With that you also have redundancy in case of a failing stack-member.
