ARUBA 8325 SWITCH SERIES
High Performance Enterprise Campus and Data Center Switch
PRODUCT OVERVIEW
The Aruba 8325 Switch Series oers a exible and innovative
approach to addressing the application, security, and
scalability demands of the mobile, cloud and IoT era.
These switches serve the needs of the next generation
core and aggregation layer, as well as emerging data center
requirements at the Top of Rack (ToR) and End of Row (EoR).
They provide over 6.4Tbps of capacity, with line-rate
Gigabit Ethernet interfaces including 10Gbps, 25Gbps,
40Gbps, and 100Gbps.
The 8325 series includes industr y-leading line rate
ports 1/10/25GbE (SFP/SFP+/SFP28) and 40/100GbE
(QSFP+/QSFP28) with connectivity in a compact 1U form
factor. These switches oer a fantastic investment for
customers wanting to migrate from older 1GbE/10GbE to
faster 25GbE, or 10GbE/40GbE to 100GbE ports.
PRODUCT DIFFERENTIATORS
The Aruba 8325 switch series is based on ArubaOS-CX, a
modern, database-driven operating system that automates
and simplies many critical and complex tasks. The
enhanced capabilities of ArubaOS-CX provide a unique set of
dierentiators for campus and data center switching.
KEY FEATURES

• Intelligent monitoring and visibility with Aruba
Network Analytics Engine
• High availability with industry-leading VSX
redundancy, and redundant power supplies and fans
• Designed for core/aggregation in the campus or Top
of Rack or End of Row in the data center

built-in REST APIs and Python scripts
• Advanced Layer 2/3 feature set includes BGP, OSPF,
VRF-Lite, and IPv6
• Compact 1U switch with 1/10/25GbE and
40/100GbE connectivity
Modular Architecture with ArubaOS-CX
ArubaOS-CX is built on a modular Linux architecture with
OVSDB, providing the following unique capabilities:
• Safe and powerful access to all state at all times allows
unique visibility and analytics capabilities
• REST APIs and Python scripting provide ne-grained
programmability
• Microservices architecture enables full integration with
other workow systems and services
• Continual state synchronization provides superior fault
tolerance and high availability
• All software processes communicate with the database
rather than with each other, ensuring high stability with
minimal inter-process communication
Aruba Network Analytics Engine
ArubaOS-CX includes Aruba’s Network Analytics Engine (NAE)
for advanced telemetry and automation. The NAE framework
is an industry-rst monitoring and troubleshooting system,
providing greatly improved network operations. NAE uniquely
provides the ability to monitor and easily troubleshoot
network health and congestion issues. The Time Series
Database (TSDB) may be used to store conguration and
operational state.
Customers can use data from the TSDB to write software
modules to troubleshoot problems. This data may also be
used to analyze trends, identify anomalies and predict future
capacity requirements.

Aruba Virtual Switching Extension
The ability of ArubaOS-CX to maintain synchronous state
across dual control planes allows a unique high availability
solution called Aruba Virtual Switching Extension (VSX).
VSX is delivered through redundancy gained by deploying
two chassis with an inter-switch link, with each chassis
maintaining its independent control.
Designed using the best features of existing HA technologies
such as Multi-chassis Link Aggregation (MC-LAG) and Virtual
Switching Framework (VSF), Aruba VSX enables a distributed
architecture that is highly available during upgrades or
control plane events.
PRODUCT CAPABILITIES

Provides 6.4Tbps for switching and 2,000 Mpps for
forwarding. All switching and routing are wire-speed to
meet the demands of bandwidth-intensive applications
today and in the future
• Scalable system design
Provides investment protection to support future
technologies and higher-speed connectivity
Connectivity
• High-density port options
- 32 ports of 40GbE/100GbE (QSFP+/QSFP28), or
- 48 ports of 1GbE/10GbE/25GbE (SFP/SFP+/SFP28) and
8 ports of 40GbE/100GbE (QSFP+/QSFP28) SFP+ ports
(with an optional 10GBASE-T transceiver)
• Jumbo frames
Supports high-performance backups and disaster-
recovery systems; provides a maximum frame size of
9K bytes
• Loopback
Supports internal loopback testing for maintenance
purposes and increased availability; loopback
detection protects against incorrect cabling or network
congurations and can be enabled on a per-port or
per-VLAN basis for added exibility
• Packet storm protection
Protects against unknown broadcast, multicast, or unicast
storms with user-dened thresholds
Quality of Service (QoS)
Supports the following congestion actions: strict priority (SP)
queuing and weighted fair queuing
Resiliency and high availability
• Aruba Virtual Switching Extension (VSX)
VSX enables a distributed and redundant architecture
by deploying two switches with each switch maintaining
independent control yet staying synchronized during
upgrades or failover
• Virtual Router Redundancy Protocol (VRRP)
VRRP allows groups of two switches to dynamically
back each other up to create highly available
routed environments
• Unidirectional Link Detection (UDLD)
Monitors link connectivity and shuts down ports at both
ends if unidirectional trac is detected, preventing loops
in STP-based networks
• IEEE 802.3ad LACP
Supports up to 54 LAGs, each with eight links per LAG,
with a user-selectable hashing algorithm
• Redundant power supplies
Provides N+1 high reliability with hot swappable,
redundant power supplies
• Redundant and load-sharing fans and power supplies
Increases total performance and power availability while
providing hitless, stateful failover
• Hot swappable power supply and fan modules
Allows replacement of modules without any operational
impact on other modules
• Separate data and control paths
Separates control from services and keeps service
processing isolated; increases security and performance
Management
• Management interface control
Enables or disables each of the following interfaces
depending on security preferences: console port, or
reset button
• Industry-standard CLI with a hierarchical structure
Reduces training time and expenses, and increases
productivity in multivendor installations
• Management security
Restricts access to critical conguration commands; oers
multiple privilege levels with password protection; ACLs
provide SNMP access; local and remote Syslog capabilities
allow logging of all access
