Introduction
This section describes the features of the DGS-3048.
Features
The DGS-3048 was designed for departmental and enterprise connections. As an all-gigabit-port Switch, it is ideal for
backbone and server connection. Powerful and versatile, the Switch eliminates network bottlenecks while giving users the
capability to fine-tune performance
Switch features include:
Ports
•
Forty-eight high performance 1000BASE-T ports for making 10/100/1000 connections to a backbone, end stations,
and servers.
•
Four mini-GBIC (SFP) combo ports to connect fiber optic media to another Switch, server or network backbone.
•
RS-232 DCE Diagnostic port (console port) for setting up and managing the Switch via a connection to a console
terminal or PC using a terminal emulation program.
Performance Features
•
Store-and-forward switching scheme.
•
Switching fabric: 96Gbps
•
Max. Forwarding Rate: 35.7 million packets per second
•
High-speed data forwarding rate of 1,488,095 pps per port at 100% of wire-speed for 1000 Mbps speed.
•
Supports 8K MAC address.
•
Supports four priority queues per port.
•
Supports 512Kbytes buffer memory per Switch.
•
802.1D Spanning Tree support. Can be disabled on the entire Switch or on a per-port basis.

Management
•
RS-232 console port for out-of-band network management via a console terminal.
•
Spanning Tree Algorithm Protocol for creation of alternative backup paths and prevention of network loops,
including Multiple Spanning Tree (MSTP) and Rapid Spanning Tree (RSTP).
•
SNMP V.1, V2c1, and V3 network management, four groups of RMON.
•
Flash memory for software upgrades. This can be done in-band via TFTP or out-of-band via the console.
•
Built-in SNMP management:
– Bridge MIB (RFC 1493)
