Management Options - D-Link DGS-3312SR Product Manual

The stacking ports are marked IN and OUT. The IEEE 1394 compliant cable must be connected from an IN port on one
Switch to an OUT port on the next Switch in the stack.
Restrictions and Cautions for Stacking
The DGS-3312SR may serve as the Master of up to twelve additional Switches. The slave Switch units must meet the
following criteria:
•
All additional slave Switches must be the same model, that is (at the time of the writing of this manual), the slaves
must be all DES-3226S Switches. The slave unit types cannot be mixed within a single stacked group.
•
DES-3226S slave Switches must have firmware Release IV or later loaded to operate properly with the
DGS-3312SR Master.
•
The DGS-3312SR is automatically started as the Master Switch in a Switch stack.
•
It is necessary to enable stacking for each slave Switch in a stacked group before interconnecting them and before
connecting the group to the network. Stacking can be enabled by connecting to each slave through the console
port and using the CLI stacking configuration command. Before stacking has been enabled on the slaves, the
IEEE 1394 port is treated logically as an individual 1000BASE port in full-duplex mode. Since the Spanning Tree
Protocol is disabled by default, a broadcast storm will result if the stacking link is completed between Switches
that have not been properly configured.

Management Options

The system may be managed out-of-band through the console port on the front panel or in-band using Telnet, a web
browser or SNMP-based management.
Web-based Management Interface
After you have successfully installed the Switch, you can configure the Switch, monitor the LED panel, and display
statistics graphically using a web browser, such as Opera, Netscape Navigator (version 6.2 and higher) or Microsoft
Internet Explorer (version 5.0).
Command Line Console Interface through the Serial Port or Telnet
You can also connect a computer or terminal to the serial console port or use Telnet to access the Switch. The command-
line-driven interface provides complete access to all Switch management features. For a full list of commands, see the
Command Line Reference Manual, which is included on the documentation CD.
SNMP-Based Management
You can manage the Switch with an SNMP-compatible console program. The Switch is supports SNMP version 1.0,
version 2.0 and version 3.0. The SNMP agent decodes the incoming SNMP messages and responds to requests with MIB
objects stored in the database. The SNMP agent updates the MIB objects to generate statistics and counters.
The Switch supports a comprehensive set of MIB extensions:
•
RFC 1643 Ether-like MIB
•
RFC 1724 RIPv2 MIB
•
RFC 1757 RMON
DGS-3312SR Gigabit Layer 3 Switch
NOTICE:
The CLI stacking command set for the DGS-3312SR is slightly different
from the CLI stacking command set for the DES-3226S. Please refer to the CLI
Reference Manual for each Switch for details or read the instructions starting on
page 12 below.
NOTE: To access the Switch through a web browser, the computer
running the web browser must have IP-based network access to the
Switch.
