Hi Sarah

It really depends on size of the network (and money we have ), but lets assume we got a medium to large network. You need to have multilayer swicthes for distro and core layer.

Access-layer: Catalyst 2960

Distribution-layer: Catalyst 3560-X, Catalyst 3750-X, Catalyst 4500

Core-layer: Catalyst 6500

Best regards,

Depends on your budget.

There are so many combination to choose from:

Minimal budget:

Access:  2960 or 2960S

Distro:  3750X

Core:  3750X or 4500R+E with Sup7E or 6500E with Sup720 or Sup2T

Average budget:

Access:  3750X

Distro:  4500R+E with Sup7E or 4500X

Core:  6500E with Sup720 or Sup2T

High:

Access:  6500E with Sup32

Distro:  6500E with Sup720

Core:  6500E with Sup2T

DC-grade, High

Access:  Nexus 2K or 3K

Distro:  Nexus 5k

Core:  Nexus 7K

Like Leo said it depends on your budget, you can use a stack of 3750 switches and combine distribution and access layers ( if this for users- IDFs or for MDF s).

"DC" likely stands for Data Center.

PS:

For access layer, whether you want L2 or L3 will narrow your choices.

Also, and especially for access layer, chassis solutions per port cost (and performance and features) varies much dependent on line card and supervisor selection.  I.e., in large Enterprise you might see the same chassis for all three layers, but performance and cost can differ greatly.

I tried to google" DC-grade,high" but could not find any explanation. Could you please elaborate on it?

Sorry.  I just coined the term "DC-grade" and "high".  Basically "DC" stands for Data Centre grade network and with a HIGH budget.  The Nexus family is regularly surpassing the capabilities of the Catalyst switches.  It would be common sense to use a DC-grade switch for use in a DC.

If one has the money and a clean sheet of paper to start on, I'd settle for the Nexus family of switches in the Data Centre, 6509E with Sup2T in the Core, Sup720 in the distro and 4500R+E with Sup7E in the access layer.
