Symbol ES 3000 Wireless Switches

Designed for Enterprise Wireless Networking Wireless Switch

The ES 3000 from Symbol Technologies is the ideal enabler for wireless switching infrastructure environments. This standards-based Fast Ethernet/Gigabit Ethernet switch provides the reliability, security and scalability enterprises demand, while also integrating the features required to achieve optimal performance and operational efficiency in your wireless network. The ES 3000 offers a cost-effective solution with all the features required for a wireless solution, leading to a lower total cost of ownership.

Designed to Simplify Wireless Networking— and Lower Costs

All wireless infrastructure requires Ethernet connectivity. The ES 3000 offers a single platform with Ethernet connectivity and managed Power-over-Ethernet (PoE), delivering the simplicity and convenience of single vendor sourcing for Ethernet and Wireless switches. PoE greatly reduces the cost of installing power sources for Access Ports/Points, and robust PoE management capabilities simplify troubleshooting and management of PoE devices. The ES 3000 offers remote control and management, allowing hi-tech infrastructure rollout in a low-tech environment without the need for local management, reducing TCO. The ES 3000 features and functionality combine to effectively reduce the capital expenditures and operational costs associated with managing wireless networks.

The Right Features for a Wireless Switch Network Deployment

Virtual LAN (VLAN) Support

The ES 3000 provides IEEE 802.1Q VLAN support for full implementation of the Virtual AP feature, enabling segmentation, security and manageability for wired and wireless enterprise access. Wired VLANs must first be created on the network to leverage the WS 5000 Wireless Switch's Virtual AP feature, which segregates broadcast and multicast traffic on the air to maximize bandwidth and mobile device battery life.

Quality of Service (QoS)

The ES 3000 offers multilayer Quality of Service features, including the IEEE 802.1p Class of Service (CoS) and Differentiated Services (DiffServ) standards. This functionality ensures appropriate allocation of bandwidth throughout the enterprise to support mission-critical traffic and optimize performance of applications, such as latency sensitive video or Voice-over-IP. QoS features provided include classification, reclassification policing, marking, queuing, and scheduling of incoming packets, as well as queuing and scheduling of outgoing packets.

• Packet Classification
—Packet classification enables distinguish between various traffic flows as based on Layer 2 and Layer 3 QoS fields.
• QoS Queues—The ES 3000 supports four egress queues per port, providing the network administrator with additional granularity in assigning priority levels for the various applications on the network. Scheduling and congestion control of these queues are managed via a Weighted Round Robin (WRR) and Strict Priority Queuing algorithm.
• Rate Limiting/Rate Policing—Rate limiting enables the proper allocation of bandwidth, based on criteria such as Source MAC address, Destination MAC address, Source IP address, Destination IP address and/or TCP/UDP port number. Rate limiting allows the definition of two rates: a guaranteed minimum bandwidth and a second burst size.

Resilience

Robust features enable the ES 3000 to deliver the high availability and network scalability required in enterprise networks. Support for standards based IEEE 802.1d Spanning-Tree Protocol (STP), IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) and IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) enables redundant links, and fast convergence in case of network failures. Spanning tree protocol dynamically incorporates new paths to destination in case of link failures. Multiple Spanning Tree allows the network administrator to create multiple instances of Spanning Tree while Rapid Spanning tree provides for a faster recovery than ordinary Spanning tree in case of a link failure.

The ES 3000 also provides IEEE 802.3ad (Link Aggregation) which allows bundling of links between two switches. This allows network traffic to use the aggregate link as a fat-pipe. In case of failure of any link in the group, the remaining links continue to transmit traffic.

Network Security

A range of security features is supported by the ES 3000 to ensure that data privacy is protected and network service is uninterrupted. Access Control Lists (ACLs) guard against attacks such as denial-of-service by restricting access to specific portions of the network, while maintaining forwarding performance by performing lookups in hardware. Packets can be denied based on source and/or destination MAC addresses, IP addresses, or TCP/UDP ports. To provide port security, the ES 3000 offers IEEE 802.1x port-based authentication, which limits access to Ethernet ports, effectively reducing the risks of rogue client and network devices, such as wireless access points or hubs.

Performance

The ES 3000 provides line rate throughput at minimum packet sizes (4.4 Gbps/6.6 Mpps throughput).

Intelligent, Managed Power-over-Ethernet

The ES 3000 provides standards based IEEE 802.3af Power-over- Ethernet (PoE), driving network and operational costs down by eliminating the need to run power to every WLAN Access Port/Point. And the ability to remotely control and manage PoE further reduces operational costs as well as delivers a higher level of control over the wireless network. PoE management capabilities include the ability to configure power prioritization per Ethernet port, ensuring the adequate allocation of power to devices that provide critical services. In addition, the ability to remotely reset PoE devices simplifies troubleshooting, eliminates the need for technical experts at every location, and enables network administrators to remotely schedule the power down of wireless access points/ports after normal operating hours or according to enterprise policy to ensure complete security.

Dynamic power allocation enables optimal power budgeting. The ES 3000 calculates the exact amount of power each PoE device is utilizing, dynamically allocating the remaining available power in a more efficient manner than the power ranges utilized in traditional PoE classification, which rely on information provided by each PoE device. 

The ES 3000 also provides full PoE visibility. Any change in the status of the power budget and PoE devices triggers a trap or message that can be sent to management tools, ensuring an always-available and accurate view of all PoE devices.

One Complete Management Solution for Wireless Infrastructure

Comprehensive Wireless Network Management

Symbol Enterprise Mobility Manager (SEMM) software provides a consolidated view of the entire wireless infrastructure, enabling deployment, monitoring, enhanced configuration and management of all elements—ES 3000 Ethernet Switches, WS 5000 Wireless Switches, and all associated Access Ports (AP 100s and AP 300s)— from a single central location such as a Data Center or Network Operations Center.

SNMP-based Network Management

A comprehensive set of Management Information Bases (MIBs) for layer two switches enables the ES 3000 to support SNMP, enabling standard enterprise network management tools such as HP OpenView, IBM NetTivoli and CA Unicenter to perform basic monitoring, configuration and fault detection.

Web and Command Line Interface (CLI) Management

The ES 3000 offers a variety of means for configuration and deployment. A simple Web based GUI interface steps the network administrator quickly and easily through the tasks of configuring and monitoring the ES 3000. The CLI provides another standard intuitive interface to the switch. In addition, rollout of configuration to multiple Ethernet switches is simplified with a DHCP boot option, which ensures consistent configuration across all switches in the enterprise network.
