Spanning Tree is enabled.

•

Hello Time: Interval between configuration messages sent by the spanning tree algorithm

•

Max Age: Amount of time before a configuration message is discarded by the system

•

Forward Delay: Amount of time system spends in “learning” and “listening” states

•

Bridge Priority: Priority setting among other switches in the spanning tree

Disable: Disable spanning tree algorithm on the system.

4.7.2 Port Settings

On this screen, you can specify spanning tree parameters for each port. These parameters include port priority and path cost.

32

4.8 VLAN Setup

The VLAN tagging option is a standard set by the IEEE to facilitate the spanning of VLANs across multiple switches (Reference: IEEE standard 802.1Q-1998 Virtual Bridged Local Area Networks).

4.8.1 VLAN Administration

In this screen the user can add new VLAN groups by entering the VLAN ID and name.

4.8.2 VLAN Membership

Here the user can define VLAN groups by marking each port “T” (tagged) or “U” (untagged). Use the space bar to select “T” or “U”. Leaving a space blank will remove VLAN membership from the port.

4.8.3 Port VLAN ID (PVID) Settings

All untagged packets entering the switch will by default be tagged with the ID specified by the port’s

PVID. This screen allows the user to specify the PVID for each port.

4.9 Port Trunking

Note: Please make sure that Spanning Tree is disabled before you set up Port Trunking.

Port Trunking is a feature that allows multiple links between switches to work as one virtual link or aggregate link. Trunks can be defined for similar port types only. For example, a 10/100 port cannot form a port trunk with a gigabit port. For 10/100 ports, trunks can only be formed within the same cluster. A cluster is a set of eight ports.

33

4.10 Port Mirroring

Port Mirroring is a feature to help in the debugging of a network. This screen allows for the enabling or disabling of port mirroring and the setting of source and monitor ports. The monitor port will show a copy of every packet that arrives or leaves the source port.

4.11 Simple Network Management Protocol (SNMP) Management

This management protocol allows the user to configure the Community Table, Host Table and Trap Settings for the network.

4.11.1 Community Table

In the Community Table the administrator can create different community strings with customized access by choosing combinations of GET, SET and TRAP rights.

4.11.2 Host Table

The SNMP Host Table screen allows the user to add and remove hosts from access rights that have been granted to community groups. The permissions GET,

SET and TRAP are assigned to a community name and then these permissions are assigned to individual machines by adding those machines and their IP addresses to the appropriate community string.

4.11.3 Trap Settings

The SNMP Trap Settings allows for the enabling or disabling of an authentication trap:

•

Enable: The system will generate a SNMP trap upon a host authorization failure

•

Disable: The authentication traps will not be generated

All hosts in community strings with TRAP privileges will be notified when a trap condition occurs.

34

4.12 Internet Group Management Protocol (IGMP) Management

IGMP is the Internet control protocol used by IP hosts to report their multicast group memberships to any neighboring multicast router. Enable IGMP to achieve automatic multicast filtering for efficient bandwidth utilization.

4.13 Statistics

This screen views the statistics for each port.

35

Chapter 5 Firmware Update Procedure

The application firmware is field-updateable. The update procedure and the required equipment are described in this chapter.

Note: Once the system is up, it is controlled by an executing application image residing in the flash memory.

No firmware update is possible during this mode. The update can only be done when the system is resetting. To initiate this sequence, the user must set the boot mode configuration parameter to Boot from

Net during normal operation, and then perform a reset. When the Boot from NET option is set, Bootstrap can start the system with an image residing on a TFTP server on the network. Be sure that the TFTP server

residing on the network is accessible by the switch.

Note: It is highly recommended, though not necessary, to use a RS232 serial port connection to the switch during the firmware updating procedure. When using a telnet Session or web interface alone, your connection to the switch will not be available until the switch has entered forwarding mode. This takes approximately three minutes. Once completed, the software version should be verified in the Firmware

Update page. If the older version of the software has not been replaced, the unit was unable to reach the new software and booted from the old “flash” version.

The upgrade procedure is as follows:

1. Go to System Manager/Firmware Update (in the Web or Console Interface).

2. Set Boot from Net option during the normal operation.

3. Verify information such as the IP address for the TFTP Server, Gateway IP address, and the file name and its path of the new image, and then press the Submit button, in the Web, or Ctrl+W, in the console interface.

4. Restart the system with Boot from Net set.

5. Bootstrap will retrieve the new image then pass control to it.

6. The system executes the new image.

Note: The previous image in the flash will not be replaced by the new image using this option.

The image in the flash will be over-written if Boot from Net and Save option is selected.

7. If you decide to upgrade to the new image, go to Firmware Update again. Set Boot from Net and

Save option, and press the Submit button, in the Web, or Ctrl+W, in the console interface.

8. Restart the system with Boot from Net and Save set.

9. The new image should over-write the old image in the Flash memory. Verify it by going to the

Firmware Update screen and checking the Software Release information.

36

Chapter 6 Switching Concepts

The following sections provide brief explanations of some of the concepts related to switching. If more information is required, please refer to networking textbooks, online resources (i.e. www.oreillynet.com) or your MIS manager.

6.1 Spanning Tree Protocol

The Spanning Tree Protocol (STP) is part of the IEEE 802.1D standard. It provides for a redundant network without the redundant traffic through closed paths. For example, in a network without spanning tree protocol, the same message will be broadcast through multiple paths, which may start an unending packet-passing cycle. This in turn causes a great amount of extra network traffic, leading to network downtime. The STP reduces a network like this, with multiple, redundant connections, to one in which all points are connected, but where there is only one path between any two points (the connections span the entire network, and the paths are branched, like a tree).

6.1.1 How It Works

All of the bridges (a switch is a complex bridge) on the network communicate with each other using special packets of data called Bridge Protocol Data Units (BPDUs). The information exchanged in the BPDUs allows the bridges on the network to do the following:

•

Elect a single bridge to be the root bridge

•

Calculate the shortest path from each bridge to the root bridge

•

Select a designated bridge on each segment, which lies closest to the root and forwards all traffic to it

•

Select a port on each bridge to forward traffic to the root

•

Select the ports on each bridge that forward traffic, and place the redundant ports in blocking states

6.1.2 Spanning Tree Parameters

The operation of the spanning tree algorithm is governed by several parameters. You should attempt to set these parameters only if you have experience with the 802.1D specification. To set the parameters listed below, access the Spanning Tree/Bridge Settings screen (console or telnet), or the Spanning Tree/Bridge

Settings page (in the web interface).

Bridge Priority

Setting the Bridge Priority to a low value will increase the likelihood that the current bridge will become the root bridge. If the current bridge is located physically near the center of your network, you may wish to decrease the Bridge Priority from its default value of 32768 to make it become the root bridge. If the current bridge is near the edge of your network, it is best to leave the value of the Bridge Priority at its default setting.

Hello Time

This is the time period between BPDUs transmitted by each bridge. The default setting is 2 seconds.

Maximum Age

Each bridge should receive regular configuration BPDUs from the direction of the root bridge. If the maximum age timer expires before the bridge receives another BPDU, it assumes that a change in the topology has occurred, and it begins recalculating the spanning tree. The default setting for Maximum Age is

20 seconds.

37

Forward Delay

After a recalculation of the spanning tree, the Forward Delay parameter regulates the delay before each port begins transmitting traffic. If a port begins forwarding traffic too soon (before a new root bridge has been selected), the network can be adversely affected. The default value for Forward Delay is 15 seconds.

Note: The above parameters (Hello Time, Maximum Age and Forward Delay) are constrained by the following formula:

(Hello Time + 1) <= Maximum Age <= 2 x (Forward Delay – 1)

In general, reducing the values of these timers will make the spanning tree react faster when the topology changes, but may cause temporary loops as the tree stabilizes in its new configuration. Increasing the values of these timers will make the tree react more slowly to changes in topology, but will make an unintended reconfiguration less likely. All of the bridges on the network will use the values set by the root bridge. It is only necessary to reconfigure that bridge if you wish to change the parameters.

6.1.3 Spanning Tree Port Configuration

To set the Port Priority and Port Path Cost values for STP, access the Spanning Tree/Port Settings screen

(console or telnet), or the Spanning Tree/Port Settings page (in the web interface).

Port Priority

The port priority is a spanning tree parameter that ranks each port, so that if two or more ports have the same path cost, the STP selects the path with the highest priority (the lowest numerical value). By changing the priority of a port, you can make it more, or less, likely to become the root port. The default value is 128, and the value range is 0 – 255.

Port Path Cost

Port path cost is the spanning tree parameter that assigns a cost factor to each port. The lower the assigned port path cost is, the more likely that port will be accessed. The default port path cost for a 10 Mbps or 100

Mbps port is the result to the equation:

Path cost = 1000/LAN speed (in Mbps)

Therefore, for 10 Mbps ports, the default port path cost is 100. For 100Mbps ports, it is 10. To allow for faster networks, the port path cost for a 1000Mbps port is set by the standard at 4.

6.2 Full Duplex, Flow Control and Auto-negotiation

These switching concepts are all related to maintaining a high rate of data transmission necessary for an efficient network.

6.2.1 Full Duplex

Traditionally, Ethernet has operated in half duplex mode, meaning that a node or workstation could either send or receive data, but not both simultaneously. Now, with the use of structured wiring using Unshielded

Twisted Pair cabling, and switched Ethernet, a workstation may operate in full duplex mode, sending and receiving data at the same time. The ability to use full duplex mode can potentially double the basic capacity of the channel, so that a Fast Ethernet connection may carry up to 200Mbps.

In order to use full duplex, an Ethernet station must have separate channels to send and receive data. UTP cabling provides this, whereas the older coaxial Ethernet did not. The station must also have a direct connection to a switched port. A station connected to only a repeater cannot operate in full duplex mode.

Also, it is critical that both ends of the Ethernet link “agree” on whether the link will operate in full or half duplex. See 6.2.3 Auto-negotiation for more details.

38

6.2.2 Flow Control

With a link operating at a high data rate, a switch may experience occasional limitations in the buffer space used to store Ethernet frames before forwarding them. In this situation, if the sending station continues to send frames, the switch will have no option but to discard the frames. This may quickly lead to unacceptable delays in upper-level protocols.

In order to avoid unnecessarily dropping frames, a switch may implement Flow Control. Flow control is a feature that allows the switch to recognize when the buffer space is limited, and to send an Ethernet PAUSE frame to its link partner to cease transmission for a specified period. As with a full duplex link, both ends of the link must understand flow control for the mechanism to operate properly.

6.2.3 Auto-Negotiation

As discussed above, you need to make sure that both ends of a link agree about the duplex and flow control settings to be used (as well as the speed of the connection). In even a mid-sized network, making sure that all the links agree on all these parameters would be too big a job if the network manager had to configure every connection manually.

To make configuration as automatic as possible, the IEEE has defined standards so that most connections can be automatically configured by the hardware, without manual intervention. Devices can agree on the speed, duplex mode and flow control settings for each individual connection. The possible links states are ranked:

1000Mbps/Full Duplex

1000Mbps/Half Duplex (never used)

100Mbps/Full Duplex

100Mbps/Half Duplex

10Mbps/Full Duplex

10Mbps/Half Duplex

With auto-negotiation, the link partners will configure the link to operate at the highest speed and duplex state that both support.

Auto-negotiation is supported on IntraCore switches on all UTP ports. GBIC ports operate at 1Gbps only, and only in full duplex mode, so auto-negotiation is disabled for GBIC ports.

Note: If an Ethernet device that is capable of auto-negotiation is connected to a port that has autonegotiation turned off, the auto-negotiating device will default to half duplex mode. If the port that is not using auto-negotiation is set to full duplex, the link will have a duplex mismatch, and will so slow that it may be unusable. If you configure an Ethernet port to operate in full duplex mode, you must also configure the link partner to operate in full duplex. It is almost always better to let auto-negotiation take care of this for you.

39

Appendix A: Troubleshooting

In the unlikely event your network does not operate properly, follow the troubleshooting tips below:

CHECK YOUR POWER CONNECTION. Is the Power LED on? If not plug the power cord into another known working AC outlet.

CHECK YOUR NETWORK CABLE. Are the LINK LEDs on? If not, check the cable connections. Are the connectors seated correctly in each port? Make sure that the correct type of cable is connected to each port.

CHECK YOUR GBIC CONNECTOR. Are the cables inserted correctly? The receiving and transmitting plugs must be inserted into their respective receptacles correctly in order to establish a link.

40

Appendix B: VLAN Description and Examples

Packets received by the switch will be treated in the following way with regard to the Switch’s VLAN settings:

1. When an untagged packet enters a port, it will be automatically tagged with the port’s default VLAN

ID tag number. Each port has a default VLAN ID setting that is user configurable (the default setting is 1). The default VLAN ID setting for each port can be changed in that port’s respective screen in the Port Specific sub-menu (Port Manager/Port Specific).

2. When a tagged packet enters a port, the tag for that packet will be unaffected by the default VLAN

ID Setting.

3. The packet will now proceed to the VLAN specified by its VLAN ID tag number.

4. If the port in which the packet entered does not have membership with the VLAN specified by the packets VLAN ID tag, the packet will be dropped. Port VLAN membership settings are changed in the VLAN Membership page (VLAN Setup/VLAN Membership).

5. If the port has membership to the VLAN specified by the packet’s VLAN ID, the packet will be able to be sent to other ports with the same VLAN ID membership.

6. Packets leaving the switch will be either tagged or untagged depending on the setting specified for that port’s membership properties.

7. A ‘U’ for a given port and VLAN will mean that packets leaving the switch from that port and VLAN will be Untagged. A ‘T’ for a given port and VLAN will mean that packets leaving the switch from that port and VLAN will be tagged with the respective VLAN ID in which it participated in.

Two examples of VLAN setup will be given. Example 1 will step through a simple two-group VLAN setup.

Example 2 will step through a more elaborate setup illustrating all possible scenarios for a comprehensive understanding of tagged VLANs. These examples are shown from the Console interface.

Example 1

1. In the VLAN Administration page, add a new VLAN to the list, shown below as “New” with a VLAN

ID value of 2.

2. In the VLAN Membership page, use the space bar to toggle matrix until the desired ports are all members of the selected VLAN.

41

3. To allow untagged packets to participate in the ‘New’ VLAN, make sure to change the Port VLAN

IDs for the relevant ports. To access the Port VLAN ID page choose c. PVID Settings from the

VLAN Setup menu. Use the space bar to add an ‘X’ indicating which PVID is assigned to which port.

Example 2

1. Setup the following VLANs:

2. Configure the VLAN membership as follows:

3. Setup the Port VLAN IDs as follows (Note: The Port One PVID is set to 2. This must be done in the port specific page since there is no VLAN with ID 2):

42

The specific ports shown above have the following Port VLAN ID settings (The Port VLAN ID settings for each port are configured in their respective Port Specific screen (in the Port Manager Menu) or in the VLAN

Administration page):

Port 01: 2

Port 02: 15

Port 03: 1

Port 05: 5

Port 06: 1

Port 07: 1

Port 09: 10

Port 10: 1

Port 11: 10

Port 04: 1 Port 08: 1 Port 12: 10

The following scenarios will produce results as described below:

1. If an untagged packet enters Port 4, the switch will tag it with a VLAN tag value of 1. However, since Port 4 has membership with VLAN ID 5, the packet will be dropped.

2. If a tagged packet with a VLAN tag value 5 enters Port 4, the packet will have access to Ports 5 and 1. If the packet leaves Port 5 and/or 1, it will be stripped of its tag becoming an untagged packet as it leaves the switch.

3. If an untagged packet enters Port 1, the switch will tag it with a VLAN tag value of 2. It will then be dropped since Port 1 has no membership with VLAN ID 2.

4. If a tagged packet with a VLAN tag value 10 enters Port 9, it will have access to Ports: 1, 11, and

12. If the packets leave Port 1, they will be tagged with a VLAN ID value of 10. If the packet leaves

Ports 11 or 12, it will leave as an untagged packet.

5. If a tagged packet with a VLAN tag value 1 enters Port 9, it will be dropped since Port 9 does not have membership with VLAN ID 1.
