BASIC FUNCTIONS
In general, the D7600 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.
User’s Manual 5
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.
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.
User’s Manual 6
User’s Manual 7
Manageable 8/9-Port Switch
MULTICAST SWITCHING
For multicast switching, the D7600 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 D7600 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 D7600 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 D7600 supports one Spanning Tree per bridged network.
User’s Manual 8
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.
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.
User’s Manual 9
User’s Manual 10
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)
IGMP SNOOPING AND IP MULTICAST FILTERING
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.
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 11
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 Via RS-232 Console Port:
The switch provides an on board serial port, which allows the switch to be configured via a directly connected terminal or a Telnet session.

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 modem 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
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.
User’s Manual 21
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:
http://help.netscape.com/filelib.html#smartupdate
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:
http://www.microsoft.com/msdownload/iebuild/ie4sp1_win32/en/ie4sp1_win3
If the above link is unavailable, download the service pack from the Microsoft home page:
http://www.microsoft.com
User’s Manual 22
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. The default
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 virtual terminal protocol.
Note: Terminal emulation is different from a virtual terminal protocol in that you must connect a terminal 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 factory 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.
