Page 26: Connecting The Switch
MDI-II port must connect to an MDI-X port. An end node can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP straight cable (be sure to use Category 5 UTP or STP cabling for 100 Mbps Fast Ethernet connections). The end node should be connected to any of the twenty-two ports (1x - 22x) of the Switch or to either of the two 100BASE-TX ports on the front-panel module that came preinstalled on the Switch.
Page 27: 10Base-T Device
If the other switch or hub contains an unused Uplink port, we suggest connecting the other device’s Uplink (MDI-II) port to any of the switch’s (MDI-X) ports (1x - 22x, or one of the 100BASE-TX module ports) using a normal straight-through cable, as shown below.
Page 28: Switch Management Concepts
Switch. Hardware components in the Switch allow it to be an active part of a manageable network. These components include a CPU, memory for data storage, other related hardware, and SNMP agent firmware. Activities on the Switch can be monitored with these components, while the Switch can be manipulated to carry out specific tasks.
Page 29: Ip Addresses And Snmp Community Names
Traps Traps are messages that alert you of events that occur on the Switch. The events can be as serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change. The Switch generates traps and sends them to the network manager (trap managers).
Page 30: Mibs
Switch transmits that packet through Port 2 only, and transmits nothing through the other ports. Aging Time The Aging Time is a parameter that affects the auto-learn process of the Switch in terms of the network configuration. Dynamic Entries, which make up the auto-learned-node address, are aged out of the address table according to the Aging Time that you set.
Page 31: Filtering Database
These backup paths are idle until the Switch determines that a problem has developed in the primary paths. When a primary path is lost, the switch providing the alternative path will automatically go into service with no operator intervention. This automatic network reconfiguration provides maximum uptime to network users.
Page 32: Sta Operation Levels
Designated Bridge. Root Path Cost The Root Path Cost of a switch is the sum of the Path Cost of the Root Port and the Root Path Costs of all the switches that the packet goes through. The Root Path Cost of the Root Bridge is zero.
Page 33: Illustration Of Sta
Stackable NWay Ethernet Switch User’s Guide Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
Page 34: Port Trunking
The Switch supports 3 trunk groups, which may include from 2 to 8 switch ports each, except for the third trunk group which consists of the 2 ports of the Slot 1, 100BASE-TX or 100BASE-FX front-panel module. The anchor port for the first group is preset as port 5, the anchor port for the second group is port 13 and the anchor port for the third group is the first port (1x) on the 2-port module.
Page 35: Vlan
Stackable NWay Ethernet Switch User’s Guide Figure 5-3. Port trunking example The switch treats all ports in a trunk group as a single port. As such, trunk ports will not be blocked by Spanning Tree (unless a redundant link with higher STP priority is present).

VLAN 2 packets). If port 10 is not a member of VLAN 2, then the packet will be dropped by the switch and will not reach it’s destination. If Port 10 is a member of VLAN 2, the packet will go through.
Page 37: Vlans Spanning Multiple Switches
Egress port A port on a switch where packets are flowing out of the switch, either to another switch or to an end station, and tagging decisions must be made. If an egress port is connected to an 802.1Q-compliant switch, tagging should be enabled so the other switch can take VLAN data into account when making forwarding decisions.
Page 38: Vlans Over 802.1Q-Compliant Switches
Broadcast transmissions, packets sent to every device on the LAN, are a vital part of any network. However, they can often cause problems on the network and even network failure. For this reason the Switch has a number of tools for managing broadcast packets on your network.
Page 39: Broadcast Storms
Port-based Broadcast Packet Filter The Switch is equipped with sensors that count the number of broadcast frames arriving at each port. When a certain level (rising threshold) is reached, the sensors can initiate a broadcast filter (rising action) which drops all broadcast packets arriving at the affected port.
Page 40: Using The Console Interface
Your Stackable NWay Ethernet Switch supports a console management interface that allows you to set up and control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP Telnet protocol. You can use this facility to perform many basic network management functions. In addition, the console program will allow you to set up the Switch for management using an SNMP-based network management system.
Page 41: Connecting To The Switch Using Telnet
Connecting to the Switch Using Telnet Once you have set an IP address for your Switch, you can use a Telnet program (in a VT-100 compatible terminal mode) to access and control the Switch. Most of the screens are identical, whether accessed from the console port or from a Telnet interface.

RAM, and will immediately take effect. Some settings, though, require you to restart the Switch before they will take effect. Restarting the Switch will erase all settings in RAM and reload them from the NV-RAM. Thus, it is necessary to save all settings to the NV-RAM before restarting the Switch.
Page 45: Login On The Switch Console By Registered Users
Figure 6-4. Save Changes screen After the settings have been saved to NV-RAM, they will become the default settings for the Switch, and they will be used every time it is powered on, reset or rebooted. The only exception to this is a factory reset, which will clear all settings and restore them to their initial values listed in Appendix D, which were present when the Switch was purchased.

Page 55: Configure Port
If a port is partitioned, the Switch can only transmit data, not receive it. Head Of Line (HOL) Blocking Prevention Enables or disables Head-Of-Line Blocking Prevention.
Page 56 Flow Ctrl Toggles flow control On or Off. It is useful during periods of heavy network activity when the Switch’s buffers can receive too much traffic and fill up faster than the Switch can forward the information. In such cases, the Switch will intervene and tell the transmitting device to pause to allow the information in the port buffer to be sent.
Page 57: Configure Trunk
They are read-only fields and cannot be changed. Configure Trunk Ports on the Switch can be grouped together in a single logical port called a trunk. This is discussed in detail in the Port Trunking section of the “Switch Management Concepts” chapter of this manual.
Page 58 Anchor There are either two or three listings representing the anchor port for each of the three trunk groups available on the Switch (the third listing will only be displayed if an optional two-port plug-in module is being used). The anchor port must fall within the port range and be included as a member port.
Page 59: Configure Port Mirroring

BPDU packets sent by the Root Bridge to tell all other switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
Page 63: Configure Filtering And Forwarding Table
Configure Filtering and Forwarding Table When a packet hits the Switch, it looks in the filtering and forwarding tables to decide what to do with the packet; either to filter it off the network, or to forward it through the port on which its destination lies.
Page 64 The Configure Filtering and Forwarding table screen allows you to stop or start address learning, change the way the Switch treats MAC address table entries, and select an age-out time of the MAC address in the selected address table. This screen also permits you to access three additional configuration screens from the menu at the bottom of the window.
Page 65: Configure Static Forwarding Table Entry
A total of ten destination addresses per page will be seen at the bottom of the screen. The Switch can hold up to 256 entries. Using the Console Interface...
Page 66: Configure Mac Address Filtering
Switch, Module, and Port The Switch, module, and port number are entered in these fields at the top of the screen. The Switch will always forward traffic to the specified device through this port. The bottom of the screen will display each corresponding destination address for these three items.
Page 67: Configure Permanent Multicast Filtering
Filtering is enabled, the Switch can intelligently forward (rather that broadcast) IGMP queries and reports sent between devices connected to the Switch and an IGMP-enabled device hosting IGMP on your network. Basically, in these submenus you define whether the Switch can intelligently forward IGMP packets, and you must also define which 802.1Q VLANs (if present) can send and receive IGMP and Multicast packets.
Page 68 IGMP and Multicast packets instead of broadcasting (flooding) them on all ports. This setting also enables IGMP Snooping, which enables the switch to read IGMP packets being forwarded through the switch in order to obtain forwarding information from them (learn which ports contain Multicast members).
Page 69 Stackable NWay Ethernet Switch User’s Guide Figure 6-25. IEEE 802.1q IGMP Configuration screen Choose Add/Remove IGMP Control Table from the screen above to define up to 12 VLANs on the Switch which can send and receive IGMP packets: Using the Console Interface...
Page 70 The above screen is used to specify an agent to interface between IGMP and VLAN. The agents are assigned to a VLAN and allow IGMP query and report packets to be present on the given VLAN. Only 12 agents can exist on the switch at any one time. Items in the above screen are described below: Action Adds/Removes an entry (agent) from the table.
Page 71: Configure Vlans & Mac-Based Broadcast Domains
VLAN ID This is the VID number for the VLAN that has an agent attached to it which enables IGMP packets to be sent and received. Age-out Timer If no IGMP query packet has arrived at the Switch before this timer has expired, the Switch will become the IGMP host for this VLAN.
Page 72: Configure Mac-Based Broadcast Domains
SNMP Vlan If the IEEE 802.1Q VLANs mode is selected, you must also enter a SNMP VLAN ID number in this field. This is a special VLAN that you designate for SNMP management packets. Make sure the Switch port that the management station is connected to has this PVID number and is a static member of this VLAN.
Page 73 Stackable NWay Ethernet Switch User’s Guide Please note that if the mode is set to MAC-Based Broadcast Domains, then the Port Lock function is not supported in the Port Configuration screen and the Lock Address Table function located on the Configure Filtering and Forwarding table screen is not available.
Page 74 Broadcast Domains and Number of Members reflect the current status. They are read-only fields and cannot be changed. Choose Add/Remove MAC-based Broadcast Domain Members from the MAC-Based Broadcast Domains Configuration menu to access the following screen: Stackable NWay Ethernet Switch User’s Guide Using the Console Interface...

The following Add/Remove MAC-based Broadcast Domain Members screen appears: Using the Console Interface...
Page 76: Configure Ieee 802.1Q Vlans
MAC Address The MAC address of the broadcast domain member being added or removed. Please note that the Status field for the MAC address you have entered may read Not-Apply. Once the Switch is restarted in MAC-based broadcast domain mode, the MAC-addresses will be applied, meaning that the broadcast domain is active.
Page 77 Stackable NWay Ethernet Switch User’s Guide 2. Define which ports will be active members of the VLAN. A port can transmit packets onto only one VLAN. It can receive packets (be a passive member) on many VLANs. Active VLANs are designations defined by assigning Port VLAN ID numbers (PVIDs) in the Default port VLAN assignment screen.
Page 78 Stackable NWay Ethernet Switch User’s Guide Figure 6-34. Ingress Filtering Check screen This screen allows you to set Ingress filtering for each port to either Enabled or Disabled. When a packet arrives at the port and Ingress filtering is Enabled, the port will check the VLAN ID number of the packet, and its own VIDs.
Page 79 Stackable NWay Ethernet Switch User’s Guide Figure 6-35. Default port VLAN assignment screen This screen allows you to set a Default port VLAN ID number (PVID) for each port. Press CTRL+S to let the changes take effect.

Page 107: Port Trunk
4. Configure the Locked setting to prevent the port from learning the MAC addresses of new hosts. This will help keep intruders off your network since any packet coming from an unknown source address will be dropped by the Switch, that is, not added to your MAC Address Forwarding Table. Select Enabled or Disabled.
Page 108: Port Mirroring
The Switch supports up to three trunk groups. Trunks are groups of ports that are banded together to form a single, logical, high-bandwidth data pipe. Items in the above window are defined as follows: Anchor The Anchor port for the trunk group. All configuration settings changes made to the anchor port will automatically be made to the other ports in the trunk.

BPDU packets sent by the Root Bridge to tell all other switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
Page 111: Forwarding And Filtering
Forwarding and Filtering When a packet hits the Switch, it looks in the filtering and forwarding tables to decide what to do with the packet; either to filter it off the network, or to forward it through the port on which its destination lies.
Page 112: Static Forwarding Table
Lock Address Table(Stop Learning) Mostly used for security purposes, when the forwarding table is locked the Switch will no longer learn the MAC addresses for new hosts. If your network configuration doesn’t change, locking the forwarding table helps keep intruders off your network since any packet coming from an unknown source address will be dropped by the Switch.
Page 113 Stackable NWay Ethernet Switch User’s Guide To use the MAC forwarding function, enter the MAC address of the device to which the specified port permanently forwards traffic in the Destination MAC Address field and enter the port number that permanently forwards traffic from the specified device in the Destination Port Number field.
