Hi Anug,

The Cisco StackWise interconnect technology is designed with two       counter-rotating paths of 16 Gb each. In order to efficiently load balance       traffic, packets are allocated between these two logical counter-rotating       paths, which creates the 32-Gb interconnection. There are dual paths from any       port to any other port within the Catalyst 3750 stack. Therefore, maximum       uptime is ensured because there is always an alternate path available if a       failure occurs in either path. The Catalyst 3750 supports:

  • Cross-stack EtherChannel

  • Cross-stack UplinkFast (with subsecond failover)

  • Cross-stack equal cost routes across different switches in the           stack

Check out the below link for more details

Hope to help !!
