Why the last port of two catalyst 3560X are connected together?

Hi,

I am a newbie here. We have two catalyst 3560X 24T-S switches connected on two separate LANs (both the networks are redundant to each other).

The last port of the switches are connected together? Please tell me what for it is done?

Regards

hi,

    It might be for incase of failure such that if link on side goes down data can still be sent from alternative path and if you check the configuration of these 2 switches rstp might also be enabled on those switches and 3rd reason is the trunking between 2 switches like leolahoo said.

Regards,

Ali
