About Smart Link

Smart Link enables the server software to detect and respond to a loss of network connectivity on the interconnect uplink ports. With Smart Link enabled, the Virtual Connect interconnects will drop the Ethernet link on all server connections associated with the network if all uplink ports within an uplink set lose their connection to the data center switches. Smart Link causes the operating system to detect a failure and direct traffic to an alternate path.

In order for the Smart Link functionality to operate as designed, valid DCC (Device Control Channel)-compatible NIC firmware and drivers must be installed on the server.

Smart Link can be helpful when using certain server network teaming (bonding) policies.

Smart Link must be enabled for active/active, horizontal stacking, and primary-slice configurations.
