COST-EFFECTIVE PERFORMANCE
Affordability
The BayStack 310-24T Switch delivers excellent affordability for businesses that are building their networks with future growth in mind.
Scalable High Speed Uplinks
Along with a built-in autosensing 10BASE-T/100BASE-TX port, two media dependent adapter (MDA) slots are provided, each accepting either a10BASE-T/
100BASE-TX or 100BASE-FX MDA. This provides investment protection, enabling a performance boost to the
network at any point in the future,
when it is needed.
Flexible High Speed
Cabling Choices
Two MDA slots allow Fast Ethernet
connectivity for both copper and fiber cabling, in any combination. The autosensing 10BASE-T/100BASE-TX MDA is an affordable option for high speed performance to nearby devices.
The 100BASE-FX MDA enables you
to extend a high-performance link over long distances (2km), perhaps to the
network center on a separate floor.
MultiLink Trunking
This software feature enables high speed switch links to be aggregated to provide higher bandwidth to a particular device. Up to 600 Mbps of throughput can be achieved via the three available Fast Ethernet ports, providing a performance boost to highly utilized network center switches or local servers.
MANAGEMENT
Flexible Management Options
BayStack 310-24T Switches can be configured and managed by console interface, Telnet, or any Simple Network Management Protocol (SNMP)-compatible application such as the Nortel Networks Optivity network management system. In addition to full management via Optivity, or Web-based management, an easy-to-use menu-driven interface can be accessed via console or Telnet for complete configuration and
management. Also, the use of BootP can help retrieve the network configuration
of a BayStack 310-24T Switch and some parameters from a server.
Web-based Network Management
BayStack 310-24T Switches include built-
in Web-based network management, so
network administrators can easily access
key information such as device summary,
configuration, fault management, statistics, applications, and support. Network managers can access data about their network and individual switches via the local
corporate intranet.
Fully Integrated into Optivity Network Management Software
The BayStack 310-24T Switches are fully integrated into Optivity network management software from Nortel Networks, enabling complete SNMP and RMON monitoring and control. Network administrators can manage their entire network, including all hubs, switches, and routers, from a single management station. Using Nortel Networks' Optivity can dramatically reduce the total cost of network ownership.
Concurrent RMON
on Every Port
BayStack 310-24T Switches feature concurrent RMON on every port, enabling standards-based RMON managers and Optivity applications to manage the network as well as the device. The BayStack 310-24T Switches support four groups
of RMON (Alarms, Events, History,
and Statistics) on every port.
Port Mirroring
Full RMON and RMON2 capabilities
are available for the BayStack 310-24T Switches via port mirroring, using a Nortel Networks StackProbe™ or other compatible external probe. Port mirroring copies packets flowing through a specific port and sends the replicated data to the probe, which performs detailed RMON/RMON2 analysis operations. This enables detailed analysis of switched traffic for debugging and troubleshooting.
ADVANCED FEATURES
VLAN Support
Each BayStack 310-24T Switch supports port-based Virtual LANs (VLANs) to extend the broadcast domain, segment network traffic, and improve performance and manageability. VLANs enable adds, moves, and changes to be easily accomplished, and also provide a measure of security by limiting broadcast domains. Traffic in different segments and subnets can be separated for maximum throughput and secure networking. Up to 31
port-based VLANS are supported.
VLAN Trunking (802.1Q)
Every port on the BayStack 310-24T Switch supports the IEEE standard 802.1Q. This standard enables the extension of multiple VLANs across a network over a single link. This features saves wiring costs and preserves switch ports
for other uses.
Asymmetrical MAC Addressing
High-speed uplink ports on the BayStack 310-24T Switches can be set to asymmetrical MAC addressing mode to prevent excessive flooding of switch traffic when the number of addresses in the forwarding table exceeds the switch capacity.
MAC Address Table Lookup
MAC table lookup for learned addresses allows users to look up specific MAC entries in the switch forwarding table using a specific MAC address as the access key. The entry tells you whether a specific MAC address has been learned by the switch. It also displays the associated port number on which the MAC frame was first received, making it a useful diagnostic tool to ensure switch settings are optimized for your growing network.
Spanning Tree Protocol (802.1D)
Spanning Tree Protocol (STP) detects and eliminates logical loops in a Layer 2 bridged or switched network. When multiple paths exist, the Spanning Tree algorithm automatically configures the network and places some ports on standby to form a network with the most efficient traffic paths, avoiding the continual looping of frames. If a path fails, the protocol reconfigures the network to activate standby ports and bring up redundant paths to maintain network operations.
"Fast Start " Spanning
Tree Protocol
Users can selectively disable STP on individual ports of a BayStack 310-24T Switch when the switch is set up with STP enabled. Also, with Fast Start STP, BayStack 310-24T Switch ports can transition to a faster forwarding rate than in standard 802.1D STP mode. Fast Start STP is particularly useful on ports where there may be only one device connecting into the switch and it may not be desirable to wait for the usual 30 to 35 seconds for STP convergence. Fast Start STP can provide connectivity to
stations within four seconds of the
established link.
MAC Address-based Security
BayStack 310-24T Switches have certain security measures to stop unauthorized access. MAC address-based security allows the BayStack 310-24T Switch to prevent unauthorized users from accessing the network. Network access is based on source MAC addresses of the authorized stations. In addition, the enhanced management access control feature validates user access to a BayStack 310-24T Switch against a list of IP addresses of authorized stations. Access is restricted up to eight stations whose IP addresses have been authorized for management access.
Frame Filtering
The BayStack 310-24T Switch supports limited destination address filtering to restrict communication to up to eight
specific stations. This provides tremendous administrative control of switch traffic, improving security and effectively increasing available user bandwidth by restricting most traffic from certain designated
network segments.
BayStack 310-24T Switch Applications
The BayStack 310-24T Switches are designed to meet several specific needs:
- boost the performance of 10 Mbps shared-media networks by segmenting the LAN into separate collision domains (see Figure 1).
- to deliver affordable low-density switched 10 Mbps bandwidth directly
to the desktop (See Figure 1).
- to connect users to centralized servers located in data centers, via high-speed 100BASE-TX or 100BASE-FX links
and MultiLink Trunking (See Figure 2).
- to provide additional network traffic optimization with advanced software
features, such as VLAN Trunking
(See Figure 3).
Combined with other BayStack products, such as hubs, switches, routers, Internet access, and wireless LAN equipment, the BayStack 310-24T Switch offers a simple, affordable way to add high-performance capabilities to Ethernet networks.
