Aruba ACSP study guide
Aruba ACSP · Work through your exam, one topic at a time.
The Aruba Certified Switching Professional (ACSP) is a professional-level credential from HPE Aruba Networking that validates the ability to design, deploy, and operate modern ArubaOS-CX campus switching fabrics. It is aimed at network engineers who already handle day-to-day switching and want to prove they can build resilient, secure, and automated campus networks rather than just configure individual ports. The Aruba ACSP study guide has 9 sections and about 2,298 words.
01Campus Switching Architecture and Device Deployment
Aruba campus designs usually separate access, aggregation/distribution, and core layers, though small sites collapse distribution and core. Access switches provide PoE and VLAN edge ports; aggregation devices terminate access uplinks, host Layer 3 gateways or VSX/VSF pairs, and apply policy; core devices provide high-speed transit between aggregation blocks and the data center.
278 words, about 1 min02VLANs, Trunking, and Layer 2 Forwarding
A VLAN is a broadcast domain; the switch forwards frames only within it unless a Layer 3 SVI or routed port provides inter-VLAN routing. Access ports carry one untagged VLAN (PVID) and usually connect endpoints.
298 words, about 1 min03Spanning Tree Protocol and Loop Prevention
Spanning Tree prevents Layer 2 loops by electing one root bridge and placing redundant ports into a blocking or alternate role. RSTP/MSTP converge faster than legacy 802.1D.
253 words, about 1 min04Link Aggregation and Multi-Chassis LAG
Link aggregation bundles parallel links into one logical link, increasing bandwidth and redundancy. Static LAGs require manual consistency; LACP (802.3ad) negotiates with active or passive modes.
238 words, about 1 min05IP Routing and OSPF
Layer 3 forwarding uses connected routes, static routes, and dynamic protocols. An SVI or routed port is required for inter-VLAN routing; the default gateway must point to the correct next hop.
257 words, about 1 min06High Availability with VSF and VSX
VSF stacks ArubaOS-Switch devices into one logical switch with a commander and standby, using VSF links. It simplifies management and provides link-level redundancy, but requires compatible models/firmware and a split-detection method.
255 words, about 1 min07Network Security: ACLs, Port Security, and 802.1X/RADIUS
ACLs filter traffic by matching fields and applying permit/deny in order; there is an implicit deny at the end of an ACL. Standard ACLs match source; extended ACLs match source, destination, protocol, and ports.
253 words, about 1 min08Management, Monitoring, and Automation (NetEdit, NAE, REST API)
NetEdit provides centralized configuration and change management for supported Aruba switches, often using a plan-review-deploy workflow. Candidates should understand device discovery, configuration templates, compliance, and rollback concepts.
239 words, about 1 min09Troubleshooting and Diagnostics
Troubleshoot bottom-up or follow the path: physical layer, then Layer 2, then Layer 3, then application. Check interface status, speed/duplex, CRC and input errors, PoE, and transceiver diagnostics.
