What is the switching capacity and port configuration of HPE R9W87A?

The HPE Aruba CX 8100-24XF4C (R9W87A) provides up to 1.76Tbps bidirectional switching and 1,309 Mpps forwarding. It includes 24x 1/10GbE SFP/SFP+ ports with Smart Rate support (1/2.5/5/10G) and 4x 40/100GbE QSFP+/QSFP28 uplinks, enabling non-blocking wire-speed performance for data center ToR deployments.

Does the R9W87A support Layer 3 routing protocols?

Yes, it supports full L3 routing including OSPF, BGP-4, RIP-2 for IPv4/IPv6, PIM, plus dynamic VXLAN with BGP-EVPN on routed interfaces, L3 LAGs, and Hydra ports. Multicast routing handles 4,096 IGMP/MLD groups and routes, ideal for enterprise core and DCI.

What management and analytics features are included?

Built-in Network Analytics Engine (NAE) delivers real-time telemetry, automation, and visibility across the network. Supports SNMP v1/v2/v3, SSH, RADIUS/TACACS+ authentication, plus Aruba NetEdit for cloud-native management, simplifying operations in large-scale deployments.

What power and cooling options does it have?

Includes dual hot-plug 550W AC PSUs (100-240V, 47-63Hz) with 120W idle/375W max consumption. Features three hot-swappable fans for back-to-front airflow, ensuring high availability and thermal efficiency in 1U rack environments.

Is it suitable for data center top-of-rack use?

Yes, optimized for ToR with 24x10GbE ports for servers, 100GbE uplinks for spine, jumbo frames to 9000 bytes, low-latency L2/L3 features, and redundant PSUs/fans. Handles bandwidth-intensive apps in virtualized data centers effectively.

What IEEE standards does it comply with?

Complies with IEEE 802.3z/ab/ae/an/ba/by (Ethernet speeds), 802.1Q/p/s/w (VLANs/STP/QoS), 802.3ad (LACP), 802.1ab/ak (LLDP/MSTP), plus 802.3x flow control, ensuring interoperability in mixed environments.
