[norberto_cammayo]

Hi,

Can anyone help me on how can I configure a 4 pcs. of catalyst switch to appear as into a one logical switch. I mean combining all of those switches and come up with single ip address. Tnx

You need certain switches to do that. For 3750 it's called stacking. For 2900XL/3500XL switches, it's called clustering.

A switch cluster is a group of connected Catalyst switches that are managed as a single entity. In a switch cluster, 1 switch must be the command switch and up to 15 switches can be member switches. The total number of switches in a cluster cannot exceed 16 switches. The command switch is the single point of access used to configure, manage, and monitor the member switches. Cluster members can belong to only one cluster at a time.
