Guys - is it possible to use the OS CLI Teaming command:

"set network failover"

to team between switches or blades on the same vlan, or is this teaming limited to a single switch.

Server platforms with dual Ethernet network interface cards (NICs) can support NIC teaming for network fault tolerance with Cisco Unified Communications Manager. Cisco began support of NIC teaming on HP servers in the 5.0(1) release and began support on IBM servers in the 6.1(2) release. This feature allows a server to be connected to the Ethernet via two NICs and, hence, two cables. NIC teaming prevents network downtime by transferring the workload from the failed port to the working port. NIC teaming cannot be used for load balancing or increasing the interface speed.

you can enable it by

set network failover enable

Wish this be helpful

As long as the two server NICs are attached to ports in the same VLAN then they can (and really should) be on separate physical switches.

The NICs work in active/standby mode - use show network failover to see which one is active.
