NEW QUESTION # 150
A customer will be using the Spanning Tree Protocol on Dell ToR switches in the VxRail environment. How should the switch ports that are connected to the VxRail nodes be configured?
- A. Enable forwarding mode on the ports.
- B. Enable MLD snooping and querier.
- C. Set the port type to edge.
- D. Set the port mode to access.
Answer: C
Explanation:
When implementing the Spanning Tree Protocol (STP) on Top-of-Rack (TOR) switches within a Dell VxRail environment, specific interface configurations are required to ensure uninterrupted host connectivity. Standard STP port states progress through listening and learning phases, which can introduce a propagation delay of up to 30 to 50 seconds before transitioning to a forwarding state. This delay can severely disrupt ESXi node discovery, initialization, and HA clustering during node reboots or link failover events, often causing the VxRail Deployment Wizard to fail.
To circumvent this, all switch ports directly interfacing with VxRail nodes must have their port type explicitly set to edge (Choice D). Configuring the port type as edge (the equivalent of PortFast in alternative switch operating systems) mandates that the interface bypass traditional STP convergence states and enter the forwarding state immediately upon link establishment. This prevents port-blocking cycles during critical boot sequences while preventing topology change notifications from destabilizing the local network tier. Setting ports to access mode is incorrect because VxRail mandates 802.1Q VLAN trunking to multiplex management, vSAN, and vMotion traffic over the same physical interfaces.
