https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/unified-computing/whitepaper_c11-701962.htmlThe Cisco UCS 6100 Series Fabric Interconnects provide Ethernet switching capabilities for the Cisco Unified Computing System (UCS). When it comes to Ethernet switching mode on the Fabric Interconnects, the following statements hold true:
A. STP runs on the uplink ports of each VLAN, as defined by PVSTP+: Per-VLAN Spanning Tree Protocol (PVSTP+) is a Cisco proprietary protocol that enables multiple instances of Spanning Tree Protocol (STP) to run on a per-VLAN basis. This allows for efficient use of network bandwidth and redundancy while preventing loops. The statement indicates that STP runs on the uplink ports of each VLAN, as defined by PVSTP+.
B. STP runs on the uplink ports of each VLAN, as defined by MSTP: Multiple Spanning Tree Protocol (MSTP) is an IEEE standard that allows for multiple VLANs to be mapped to a single STP instance, reducing the number of STP instances running in the network. This statement indicates that STP runs on the uplink ports of each VLAN, as defined by MSTP.
C. The STP parameter configuration is unsupported: This statement suggests that the STP parameter configuration is not supported on the Cisco UCS 6100 Series Fabric Interconnects.
D. The STP parameter configuration is supported: This statement indicates that the STP parameter configuration is supported on the Cisco UCS 6100 Series Fabric Interconnects.
E. STP runs on the server ports: This statement suggests that STP runs on the server ports, which is incorrect. STP typically runs on uplink ports to prevent loops in the network.
Therefore, the correct answers are A and D. The Cisco UCS 6100 Series Fabric Interconnects support STP with PVSTP+ or MSTP configurations, and the STP parameter configuration is supported.
