Manageable 8/9-Port Switch
PLEASE NOTE:
I. Half-duplex mode uses back pressure flow control to prevent the receiving
buffer from being overrun by data from a source node.
II. Full-duplex mode uses 802.3x flow control standard to prevent fast data traffic
from overrunning slow data traffic.
III. Auto-sensing mode is in use after auto-negotiating with the other end of the link.
BASIC FUNCTIONS
In general, the D-GES7600 is responsible for switching both VLAN tagged and untagged
frames from a receiving port to one or more transmitting ports. The switch performs
multiple steps during the switching process:
VLAN CLASSIFICATION
LEARNING
FILTERING
AGING
Below is additional information about tasks that the switch performs during unicast
and multicast switching.
UNICAST SWITCHING
VLAN CLASSIFICATION
When the switch receives a frame, it classifies the frame in one of two ways:
- If the frame is untagged, the switch classifies the frame to an
associated VLAN.
- If the frame is tagged, the switch uses the tagged VLAN ID to identify the
broadcasting domain of the frame.

PLEASE NOTE:
I. Half-duplex mode uses back pressure flow control to prevent the receiving
buffer from being overrun by data from a source node.
II. Full-duplex mode uses 802.3x flow control standard to prevent fast data traffic
from overrunning slow data traffic.
III. Auto-sensing mode is in use after auto-negotiating with the other end of the link.
LEARNING
After VLAN classification, the switch checks the <source MAC address, VLAN> pair in the
switching database (SDB) to see whether the <source MAC address, VLAN> pair is known.
- If it is unknown, the switch inserts the <source MAC address, VLAN> into the SDB
and learns the <source MAC address, VLAN>.
- If it is known, the switch checks the <source MAC address, VLAN> for a mis
matched port ID. If the port ID associated with the <source MAC address, VLAN>
pair in the SDB is different than the receiving port, the switch modifies the port ID
in the SDB and modifies its management database (MDB) accordingly.
FILTERING
After learning the address, the switch checks:
- Whether the source port or destination port is in the forwarding state.
- Whether the source MAC address or destination MAC address is to be filtered.
- Whether the source port ID is the same as destination port ID.
If any of these conditions are met, the switch drops the receiving.
Otherwise, it continues with the forwarding process described below.
FORWARDING
During the forwarding process, the switch checks whether the <destination MAC address,
VLAN> pair is unknown.
- If it is unknown, the switch floods the receiving frame to all ports in the VLAN,
excluding the source port.
- If it is known, the switch forwards the receiving frame to the port associated
with the <destination MAC address, VLAN> pair. At the same time, the switch
ascertains the individual’s ports VLAN tagging and/or un-tagging configuration
and corresponding VLAN ID render the appropriate frame tagging when the frame
is ready to be transmitted.
’s Manual 6
User
Manageable 8/9-Port Switch
MULTICAST SWITCHING
For multicast switching, the D-GES7600 checks whether the received frame is a BPDU. If a
BPDU is received, the switch forwards the frame to the CPU for processing by the spanning
tree protocol. Otherwise, the D-GES7600 performs the following processes:
VLAN CLASSIFICATION
Same as for unicast switching.
LEARNING
Same as for unicast switching.
FILTERING
After learning the address, the switch checks:
- Whether the source port or destination port is not in the following state.
- Whether the source MAC address or destination MAC address is to be filtered.
If any of these conditions are met, the switch drops the receiving.
Otherwise, it continues with the forwarding process described below.
FORWARDING
The D-GES7600 floods the received multicast frame to all ports that are in the forwarding
state within the VLAN, excluding the source port. At the same time, the switch
ascertains the individual ports VLAN tagging/untagging configuration and
corresponding VLAN to render the appropriate frame tagging when the frame is
ready to be transmitted.
AGING
The switch performs the aging process for the <MAC addresses, VLAN> pair in the
switching database. Once a <MAC address, VLAN> pair is aged out, the SBD is modified.
SPANNING TREE
The D-GES7600 supports one Spanning Tree per bridged network.

VLAN
A virtual LAN (VLAN) is a network of computers or peripherals that behave as if they are
connected to the same wire, even though they may actually be physically located
in different locations of a LAN. VLANs are similar to a group of end stations, perhaps on
multiple physical LAN segments that are not inhibited by their physical location
and can communicate as if they were on a common LAN.
VLANs are configured through software rather than hardware, which makes the
extremely flexible. One of the biggest advantages of VLANs is that when a peripheral
is physically moved to another location, it can stay on the same VLAN without any
hardware reconfiguration.
Because VLANs are not limited by the hardware constraints that physically connect
traditional LAN segments to a network, they can define a network into various logical
configurations. For example, VLANs can define a network by function.
In this setting, a system integrator might create one VLAN for multimedia users
and another for email users. VLANs can also define a network by location or type
of service. For example, a location might have one VLAN for its cameras, another
for it access control, and another for its roadside signs.
VLANs can also be set up according to the organization structure within a company.
For example, the company president might have his/her own VLAN, the executive
staff might have a different VLAN, and the remaining employees might have yet another
different VLAN.
As these examples show, VLANs offer matchless flexibility. The following sections describe
how deploying VLANs can benefit system integrators and reduce design costs.
User’s Manual 8
Manageable 8/9-Port Switch
BROADCAST CONTROL
In traditional networks, traffic broadcasts to all network devices, whether they are the intended
recipients or not. However, VLANs can be set up to contain only those devices that need to
communicate with each other. As a result, VLANs considerably reduce network congestion.
In addition, VLANs prevent broadcast storms from causing a network from crashing due
to volumes of traffic.
MULTICAST-BASED MULTIMEDIA APPLICATIONS
Multimedia applications, such as interactive training, video monitoring, and video/data
transmissions, require large amounts of bandwidth. These applications are also extremely
sensitive to variable delays, which are inevitable on a shared Ethernet network. By defining a
VLAN based on the IP multicast address for all defined members on the VLAN, adequate
bandwidth will be available for these applications, providing true multimedia Ethernet.
IMPROVED SECURITY
Because VLANs are independent, only the devices within the same VLAN can
communicate with each other. If a device in one VLAN wants to communicate with
a device in another VLAN, the traffic must go through a router.
VLAN MEMBERSHIP
VLAN implementation allows:
- Up to 64 VLANs in one switch.
- VLANs across multiple switches by using explicit or implicit tagging and the
GARP/GVRP protocol defined in IEEE802.1p and 802.1Q.
- An end station’s network interface card belongs to multiple VLANs.
-A switch port to be associated with multiple VLANs
.
DEFINITIONS OF VLAN MEMBERSHIP
VLAN implementation allows VLAN membership to be defined based on ports. Physical port
numbers organizes port-based VLANs. For example, switch ports 1,2,4 and 6 can be grouped
on VLAN, while server ports 3, 5, 7 and 8 can be on another VLAN. Broadcasts from servers
within each group would only go to the members of its own VLAN. This ensures that broadcast
storms cannot cause a network to crash due to volumes of traffic.
VLAN MEMBERSHIP LEARNING
Port-based VLAN is defined using a static binding between a VLAN and its associated ports.
The switch’s forwarding decision is based on the destination MAC address and
its associated port ID. Therefore, to make valid forwarding and flooding decisions, the switch
learns the relationship of the MAC address to its related port…and thus to the VLAN…at runtime.
’s Manual 9
User
Manageable 8/9-Port Switch
REMOTE VLAN MEMBERSHIP
Additionally to providing network management tools that allow network administrators to
statically add and delete VLAN member ports, the switch also supports GVRP (GARP VLAN
Registration Protocol). GVRP allows for dynamic registration of VLAN port members within
switch and across multiple switches.
Other than supporting dynamic updating of registration entries in a switch, GVRP is
used to communicate VLAN registration information to other VLAN-aware switches,
so that a VLAN member can cover a wide span of switches on a network.
GVRP allows both VLAN-aware workstations and switches to issue and revoke VLAN
memberships. VLAN-aware switches register a propagate VLAN membership to all
ports that belong to the active topology of the VLAN.
VLAN CONFIGURATION
The switch provides a Local/Remote Management Console Interface for VLAN
configuration and management. An SNMP-based VLAN MIB is also provided.
INTRA-VLAN COMMUNICATION
The switch supports intra-VLAN communication through hardware as described in
"Basic Functions" section.
INTER-VLAN COMMUNICATION
The switch supports Inter-VLAN communication using CPU-based routing software.
GVRP (GARP VLAN Registration Protocol)
In addition to network management tools that allow network administrators to statically
add and delete VLAN member ports, the routing switch supports GARP VLAN Registration
Protocol (GVRP). GVRP supports dynamic registration of VLAN port members within a switch
and across multiple switches.
In addition to dynamically updating registration entries with a switch, GVRP is used to
communicate VLAN registration information to other VLAN-aware switches, so that
members of a VLAN can cover a wide span of switches on a network.
GVRP allows both VLAN-aware workstations and switches to issue and revoke VLAN
memberships. VLAN-aware switches register and propagate VLAN membership to all
ports that are part of the active topology of the VLAN.
IGMP SNOOPING AND IP MULTICAST FILTERING
The Internet Group Management Protocol (IGMP) runs between hosts and their immediately
neighboring multicast routers. The protocol’s mechanisms allow a host to inform its local
router that it wants to receive transmissions addressed to a specific multicast group.
Routers periodically query the LAN to determine if known group members are still active.
User’s Manual 10
Manageable 8/9-Port Switch
IGMP Snooping & IP Multicast Filtering Continued...
If there is more than one router on the LAN performing IP multicasting, one of the routers is
elected ‘querier’ and assumes the reponsibility.
Based on the group membership information learned from the IGMP, a router can
determine which (if any) multicast traffic needs to be forwarded to each of its ‘leaf’
sub-networks. Multicast routers use this information, along with a multicast routing
protocol, to support IP multicasting across the Internet.
Routing switches support IP Multicast Filtering by:
- Passively snooping on the IGMP Query and IGMP Report packets transferred
between IP Multicast Routers and IP Multicast host groups to learn about IP
Multicast group members, and
- Actively sending IGMP Query messages to solicit IP Multicast group members.
The purpose of IP multicast filtering is to optimize a switched network’s performance, so
multicast packets will only be forwarded to those ports containing multicast group hosts
members and routers instead of flooding to all ports in the subnet (VLAN).
Routing switches with IP multicast filtering/switching capability not only run passively
monitor IGMP Query and Report messages, DVMRP Probe messages, PIM, and MOSPF Hello
messages; they also actively send IGMP Query messages to learn locations of multicast
routers and member hosts in multicast groups within each VLAN.
Note, however, IGMP neither alters nor routes any IP multicast packets. Since IGMP
is not concerned with the delivery of IP multicast packets across sub-networks, an
external IP multicast router is needed if IP multicast packets have to be routed
across different sub-networks.
SWITCH MANAGEMENT

ADMINISTRATION CONSOLE
The administration console is an external, character-oriented, menu-driven user
interface for performing system administration such as displaying statistics or
changing option settings.
Using this method, you can view the administration console from a terminal, personal
computer, Apple Macintosh, or workstation connected to the switch’s console port.
There are two ways to use this management method: direct access or mode Telnet access.
The following sections describe these methods:
DIRECT ACCESS
Direct access to the administration console is achieved by directly connecting a terminal or
a PC equipped with a terminal-emulation program (such as Hyper-Terminal) to the switch
console port.
When using the management method, configure the terminal-emulation program to use
the following parameters (you can change these settings after login):
[Default Parameters] 115, 200bps
8 Data Bits
No Parity
1 Stop Bit
Flow Control None
This management method is often preferred because you can remain connected and
monitor the system during systems reboots. Also certain error messages are sent to the
Console port regardless of the interface through which the associated action was initiated.
A Macintosh or PC attachment can use any terminal-emulation program for connecting
to the terminal serial port. A workstation attachment under UNIX can use an emulator
such as TIP.
Telnet ACCESS
You can access the switch’s administration console from a PC or Macintosh using DOS
window through network with IP address. The switch management program provides a
CONSOLE PORT screen, accessible from the BASIC MANAGEMENT screen, that lets you
configure parameters for remote access.
’s Manual 20
User
Manageable 8/9-Port Switch
WEB MANAGEMENT
The switch provides a browser interface that lets you configure and manage
the switch remotely.
After you set up your IP address for the switch, you can access the switch’s web
interface applications directly in your web browser by entering the IP address of the
switch. You can then use your web browser to list and manage switch configuration
parameters from one central location, just as if you were directly connected to the
switch’s console port.
Web Management requires either Microsoft Internet Explorer 4.01 or later or Netscape
Navigator 4.03 or later.
• Netscape Navigator
If you use Netscape Navigator 4.03 or 4.04, install the Netscape JDK 1.1 Patch.
Download the patch from:

If you encounter problems accessing Help files when you use Netscape, clear the browser
memory cache and disk cache, and restart the browser.
• Internet Explorer
If you use Internet Explorer, install the latest 4.01 Service Pack 1. This service pack makes
Internet Explorer Year 2000 compliant and fixes other product-support issues. Download
the 4.01 Service Pack 1 from the following location:

SNMP-BASED NETWORK MANAGEMENT
If you enable the SNMP function through the console port, you can use an external SNMPbased application to configure and manage the switch. This management method requires
the SNMP agent on the switch and the SNMP Network Management Station to use the
same community string. This management method, in fact, uses two community strings:
the ‘get’ community string and the ‘set’ community string. If the SNMP Network management station only knows the ‘set’ community string, it can read and write to the MIBs.
However, if it only knows the ‘get’ community string, it can only read MIBs.
getting and setting community strings for the switch are public.
PROTOCOLS
The switch support the following protocols:
- Virtual Terminal Protocols, such as Telnet
A virtual terminal protocol is a software program, such as Telnet, that allows
you to establish a management session from a Macintosh, a PC, or a UNIX
workstation. Because Telnet runs over TCP/IP, you must have at least one IP
address configured on the switch before you can establish access to it with a
tual terminal protocol.
vir
The default
Note: Terminal emulation is different from a virtual terminal protocol in that you must
connect a t
erminal directly to the console port.
Simple Network Management Protocol (SNMP)
SNMP is the standard management protocol for multi-vendor IP networks. SNMP supports
transaction-based queries that allow the protocol to format messages and to transmit
information between reporting devices and data-collection programs. SNMP runs on top of
the User Datagram Protocol (UDP), offering a connectionless-mode service.
Management Architecture
All of the management application modules use the same Messaging Application
Programming Interface (MAPI). By unifying management methods with a single MAPI,
configuration parameters set using one method (e.g. console port) are immediately
displayed as the other management methods (e.g. SNMP agent of web browser).
The management architecture of the switch adheres to the IEEE open standard. This
compliance assures customers that the switch is compatible with, and will interoperate
with other solutions that adhere to the same open standard.

MENU-DRIVEN CONSOLE MANAGEMENT
The switch provides a menu-driven console interface for configuration purposes.
The switch can be configured either locally through its RS-232 port or remotely via
a Telnet session.
This section describes how to configure the switch using its menu-driven console.
Logging On To The Switch
At the screen prompt:
Switch Console Login:
Password:
Login Name
Enter the console interface factory default console name admin.
Password
Enter the factory default password (ethernav, press <Enter> directly).
Or enter a user-defined password if you followed the instructions later and
changed the factor
y default password.
Factory Default Password: ethernav, press <Enter> directly.
NOTE: Only one console and three Telnet users can log on to the switch
concurrently. However, it is not recommended that multiple users modify
the configuration at the same time.
