Both ARP-Suppression and ND-Suppression are disabled by default is not a true statement about ARP and ND Suppression. ARP-Suppression is enabled by default on ArubaOS-CX switches, while ND-Suppression is disabled by default. ARP-Suppression and ND-Suppression are features that reduce broadcast traffic on VXLAN networks by using a local ARP/ND cache on each switch instead of flooding ARP/ND requests to all VXLAN tunnel endpoints (VTEPs).

ERPS is a feature of ArubaOS-CX that prevents loops at layer 2 on ring networks. ERPS uses a protocol called Ring Auto Protection Switching (RAPS) to detect link failures and perform fast traffic switchover. ERPS has two timers that control the protection switching mechanism: guard timer and hold off timer. The guard timer prevents false switching caused by delayed or lost RAPS PDUs. The guard interval is set in units of 10 ms and should exceed the maximum expected delay for forwarding a frame around the complete ring. This ensures that all switches on the ring receive the RAPS PDUs before the guard timer expires. Therefore, this is a guideline for configuring timers for ERPS, and the correct answer is yes. For more information on ERPS and timers, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the ERPS Guide for your switch model.

Work with the server admins to assign a consistent VLAN for VMs 1 and 4. Assign interface 1/1/2 on Switch-1 to the same VLAN is part of a valid configuration to meet the requirements for providing VXLAN services for several VMs and servers using ArubaOS-CX switches. VMs 1 and
4 belong to the same VXLAN segment (VNI 5010), so they should be assigned to the same VLAN on their respective hypervisors. Interface 1/1/2 on Switch-1 should also be assigned to the same VLAN as VMs 1 and 4, so that Switch-1 can act as a VTEP for them.

Solution: It collects Information about the switch hardware.

Deploy Aruba CX 6300 switches as data center spine switches is not a best practice when positioning ArubaOS-CX switches in data center networks. The Aruba CX 6300 switches are designed for data center leaf roles, and they provide high density, low latency, and advanced features such as VSX and EVPN. The Aruba CX 83xx switches are more suitable for data center spine roles, and they provide high performance, scalability, and resiliency.
