HPE Aruba S2500 Mobility Access Switch: технические характеристики и документация

Aruba S2500 Mobility Access Switch

Product overview

The S2500 Mobility Access Switch from Aruba Networks® extends role-based user access, security and operational simplicity to wired networks.

A vital part of Aruba Mobility-Defined Networks^TM, the S2500 delivers secure, virtualized access services to users, regardless of their location, access method, device or applications.

The S2500 is available in three models, with 24 or 48 10/100/1000BASE-T ports and power-over Ethernet (PoE) options.

Each model includes four fixed Gigabit Ethernet/10 Gigabit Ethernet uplink ports. Power-over-Ethernet (PoE) is available with up to 30 watts per port based on the IEEE 802.3af PoE and 802.3at PoE+ standards.

Mobility Access Switches can be interconnected to form an ArubaStack^TM. This provides connectivity for APs, virtual desktops, IP phones, videophones, classroom peripherals, medical devices, point-of-sale devices and security cameras.

The feature richness of the S2500, along with its compact form factor and quiet operation, make it ideal for branch office and small office deployments.

Features and Benefits

Flexible and Secure Access Deployments  

What makes Aruba Mobility Access Switches unique is their ability to apply role-based policies to wired users and devices. User roles can represent specific users or groups of users with defined names such as employees or guests. They can be defined with VLAN-IDs, QoS policies, VoIP policies or even ACLs. 

Dynamic policy enforcement with ClearPass

When deployed with Aruba ClearPass, which provides user and device authentication, user roles may be automatically downloaded and applied to the Mobility Access Switch.

If a user's authorization parameters change - for example, if user access extends outside time-of-day parameters or disabling a firewall violates device health check policies - ClearPass can signal Mobility Access Switches to change the user role associated with the client.

The integration and automation of policy management capabilities significantly reduces IT overhead by eliminating the need to manually configure policies on every Mobility Access Switch.

Wired AP with Mobility Controllers

Mobility Access Switches support a unique per-port Tunneled Node capability that enables policy enforcement by an

ICSA-certified stateful firewall resident in Aruba Mobility Controllers. A Tunneled Node port essentially operates as a wired AP, identical to Aruba 802.11ac APs.

Ports in shared locations such as conference rooms and common areas can be configured so that traffic is enforced by the Mobility Controller firewall, while other ports perform local forwarding.

Configured as a wired AP, Mobility Access Switches free network administrators from the need to configure VLANs, ACLs and QoS policies at each switch in the access layer.

Policies for users, devices and applications are defined and enforced by Mobility Controllers across wired and wireless networks

ArubaStack extends beyond the wiring closet 

With ArubaStack, Mobility Access Switches provide the opportunity to optimize network access design. Up to eight S2500 or S3500 Mobility Access Switches can be interconnected and managed as a single logical device with one IP address and one configuration file. 

Each S2500 includes four integrated Gigabit Ethernet/10 Gigabit Ethernet ports to enable stacking. 

With ArubaStack, 1000bASE-X/10GbASE-X ports are used for the stack interconnects. Each S2500 uplink module comes with a 50-cm direct-attach copper cable used to create an ArubaStack in the wiring closet. 

Extending the ArubaStack to other Mobility Access Switches across closets or buildings can be achieved using both fiber and copper interfaces (see Figure 2). 

Interconnecting multiple wiring closets into a single ArubaStack reduces uplinks and expensive routed ports in the LAN core, simplifies LAN topologies, and reduces capital and operating costs compared to legacy wiring closet designs. 

The S2500 provides a compact, quiet and economical solution for deployments in traditional intermediate distribution frame (IDF) locations and in open areas like classrooms and conference rooms. For smaller network environments, pairing the S2500 with the S3500-24F provides a robust low-cost solution.

 Free IT staff from tedious network configuration

 Mobility Access Switches support several features that reduce the cost, complexity and time to perform configurations and upgrades. 

Utilizing port-profiles ensures that ports are configured correctly the first time and simplifies configuration compliance with additional port configuration changes. 

When used with Aruba Instant^TM APs, Mobility Access Switches automatically learn VLANs configured in the Instant cluster. 

Mobility Access Switches additionally modify the port PoE priority as a business-critical resource, reserving power for APs in the event of loss of budgeted PoE power. They can also shut down a port classified as a rogue AP by an Aruba Instant AP. 

The automation with Aruba Instant, and integration with ClearPass and Mobility Controllers, eliminates traditional IT overhead that comes from manually configuring parameters and policies on every legacy switch in the access network. 

Mobility Access Switches can also utilize the Aruba Activate^TM zero-touch provisioning service, which enables customers to efficiently deploy and maintain Aruba devices across a distributed enterprise. 

Customers that subscribe to Aruba Central cloud-based network management can also leverage Aruba Activate to categorize and set specific provisioning parameters that enable Aruba devices to automatically obtain their configurations. The benefits of the combined Aruba Central and Aruba Activate integration include: 

• Asset tracking and device categorization within the customer organization.
• Reduced time-to-deploy across a large number of locations.
• Automated software-update notifications and simplified upgrades.

High Availability Features 

The S2500 includes a number of features that make it ideal to deploy in networks that require maximum availability. 

• Distributed link aggregation: Link aggregation groups (LAG) with physical ports may be shared across members of an ArubaStack. This distribution of a LAG across the ArubaStack allows load-sharing and redundant connections across multiple devices, providing an additional level of reliability and maximum availability.
• PoE priority: ArubaOS PoE priority classifies attached PoE devices with a priority level, ensuring no loss of power for business-critical devices like APs, security cameras and red phones.
• Hot Standby Link (hSL): ArubaOS hSL provides a simplified link failover mechanism without configuring and running the spanning-tree protocol. A port or group of ports may be configured as redundant for another port or group of ports.
• ArubaStack with S3500: All S2500 models may be a member of an ArubaStack concurrently with S3500 models. The S3500, with its redundant power and field- replaceable fan tray, provides an added level of hardware availability for network- critical devices
