Switch Architecture

The Gigabit Ethernet Switches employ a wire-speed, non-blocking switching fabric.

This permits simultaneous wire-speed transport of multiple packets at low latency on

all ports. These switches also feature full duplex capability on all ports, which

effectively doubles the bandwidth of each connection.

For communications between different VLANs, these switches use IP routing. For

communications within the same VLAN, they use store-and-forward switching to

ensure maximum data integrity. With store-and-forward switching, the entire packet

must be received into a buffer and checked for validity before being forwarded. This

prevents errors from being propagated throughout the network.

These switches include built-in stacking ports that enable up to eight units to be

connected together through a 40 Gbps stack backplane. The switch stack can be

managed from a master unit using a single IP address.

These switches include a slot on the rear panel for slide-in single-port 10GBASE-LR

modules with Xenpak or XFP transceivers.

Network Management Options

These switches contain a comprehensive array of LEDs for “at-a-glance” monitoring

of network and port status. They also include a management agent that allows you

to configure or monitor the switch using its embedded management software, or via

SNMP applications. To manage each switch, you can make a direct connection to

the RS-232 console port (out-of-band), or you can manage the switches through a

network connection (in-band) using Telnet, the on-board Web agent, or

SNMP-based network management software.

For a detailed description of both switches’ advanced features, refer to the Gigabit

Ethernet Switch Management Guide.
