I think :
End-Host Mode :
– This is the default mode opération
– link active-active
Switch mode :
– STP
– MAC
End-host mode features include:
– Spanning Tree Protocol is not run on both the uplink ports and the server ports.
– MAC address learning occurs only on the server ports; MAC address movement is fully supported.
– Links are active-active regardless of the number of uplink switches.
– The system is highly scalable because the control plane is not occupied.
Ethernet switching mode features include:
– Spanning Tree Protocol is run on the uplink ports per VLAN as defined by Cisco® Per-VLAN Spanning Tree Plus (PVST+)
– Configuration of Spanning Tree Protocol parameters (bridge priority, hello timers, etc.) is not supported.
– VLAN Trunk Protocol (VTP) is not supported.
– MAC address learning and aging occur on both the server and uplink ports as in a typical Layer 2 switch.
– Upstream links are blocked according to Spanning Tree Protocol rules.

i think switching mode is stp on uplink port and mac address learning on uplink
Note: This document does not discuss the operating mode available on the Fibre Channel ports.

For Ethernet, end-host mode is the default mode of operation. A change in the operating mode requires a fabric interconnect reboot to effect the change (Figure 2).
so the default mode is end-host mode. this answer is incorrect.
