Management Methods

The 24 Port SNMP Managed Switch supports following management methods:

• Console and Telnet Management

• Web-based Management

• SNMP Network Management

Console and Telnet Management

Console Management is done through the RS-232 Console Port. Managing the 24 Port SNMP Managed Switch in this method requires a direct connection between PC and the 24 Port SNMP Managed Switch. While Telnet management is done over the network. Once the 24 Port SNMP Managed Switch is on the network, you can use Telnet to log in and change the configuration. The automatic log-out times can be programmed and are detailed on pages 36 and 56. See page 12 for details.

Web Based Management

The switch can be managed using a standard web browser that supports Java applets. This interface has the same functionality as the console/Telnet interfaces but is more user-friendly. See page 38 for details.

SNMP Network Management

SNMP (Simple Network Management Protocol) provides a means to monitor and control a network device, and to manage configurations, statistic collection, performance and security. Data is passed from SNMP agents, which are hardware & software processes reporting activity in each network device to the workstation console used to oversee the network. The agent returns information contained in a MIB (Management Information Base), which is a data structure that defines what is obtainable from the device and what can be controlled.

Quick Start Guide

If you do not need to apply VLANs, Quality of Service, adjust any settings or manage the switch via the network, then the switch can be used “straight-from-the-box” to carry network traffic. In that case, no further action is needed. If you want to use the management settings or controls, then a little work is needed to configure the switch.

1. After the installation is completed and AC power is applied to the switch, the unit will automatically perform a diagnostic test. The switch loads its operating code from memory and performs a full power-on self test. The screen will display the self-test progress, but do not press any keys at this stage. This power-up sequence takes approx. 90 seconds to complete. The web interface will take a further 30 seconds to become operational.

2. Configure you PC terminal emulation program such as HyperTerminal to allow it to communicate with the switch via the supplied serial cable connected to the front panel Console port. Set the emulation program for 9600, 8, No Parity, No Flow Control. See page 12 for details

3. When the password and user name prompt is displayed, use the default username of root in lower case letters. Use the password root. The main menu screen will be displayed. Use either cursor keys or the tab key to navigate up and down the menu. Select the item using the <CR> key. The <ESC> key will return you to the previous menu level.

4. If the switch is to be managed over the LAN using the Telnet, SNMP or the web browser functions, then an IP address is to be assigned to the switch. See page 14 for details. If the switch is not being managed over the LAN, then go to page 12 below.

5. Once an IP address has been assigned to the switch, it should be possible to PING the switch over the network. This will prove that the switch is present and responding correctly to network requests. See page …. For details.

6. Now that the switch can be accessed over the network, use a browser application to open up the configuration screens. Enter the switch IP address into the browser Address window and use the same user name and password set as in 3 above.

7. Using the preferred method (console, Telnet or web browser), configure the switch to meet your network requirements. Always save the configuration at the end of each action.

8. If you need to revert the switch back to the factory default configuration, then see page 36 or page 55.

24 Port SNMP Managed Switch – User Manual Page 19

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

The Switch Device Configuration menu options are listed below. Use the <space> bar to toggle modes, or enter time values directly:-

• The Spanning Tree Protocol for the switch is enabled or disabled in this menu.

• The Dynamic Ageing Time is the number of seconds that an entry will be stored in

the switch ARL table before it is aged out. The default is 300 seconds, but in some test applications, it may be desirable to reduce this time.

• Ingress filtering when enabled the switch will reject all tagged VLAN traffic not

intended for the port that is receiving the tagged packet.

• The Per Port Priority control allows the ports to be allocated specific priority values

from the Switch Port Configuration menu.

• The HOLB Prevention control either enables or disables Head Of Line Blocking. This

is an advanced function associated with egress flow control and heavily loaded networks where it is desirable to constrain the use of switch buffers to protect other ports. It is recommended that this control is left in the <enabled> state for normal network applications.

• When QoS (Quality of Service) is enabled you can map the Type of Service of your

choice (according to IEEE 802.1p) to the four priority levels provided.

• The switch supports three different VLAN modes:-

o Port Based VLAN, o IEEE 802.1Q VLAN o MTU/MDU VLAN.

The choice made here will ultimately decide the VLAN mode and function for the entire switch. See Below for VLAN description.

• The GVRP Enable State allows structured and centralized VLAN registration in multi-

switch networks, To enable this function, use the <space> bar to toggle the enable/disable mode.

• The IGMP Snooping mode is used for multicast environments where the switch

participates in multicast operations. To enable this function, use the <space> bar to toggle the enable/disable mode.

• The IGMP Snoop Table Ageing time sets the timeout for multicasts. Enter the value

directly into this field.

Port Based VLAN

This mode is the simplest form of VLAN and is intended where basic VLANs on a single switch are required. This mode allows specified physical ports on the switch to be grouped into single collision domains to prevent any traffic from other domains entering that zone. An example is where the Engineering workstations must not be allowed to access the HR network area. The security of Port Based VLANs is limited and dependant on the physical security of the switch and its connections. The IEEE802.1Q tag attribute is ignored by Port Based VLANs .

IEEE 802.1Q VLAN

This is a more common form of enterprise VLAN where traffic is tagged with a VLAN identifier, which specifies which groups can receive the traffic. Each packet is tagged with a VLAN ID number and the switch makes decisions on the logical groupings of these VLAN Ids. For example, Engineering may be assigned VLANID 20, Sales assigned VLAN ID 30 and HR assigned VLAN ID 40.

MTU/MDU VLAN

This mode is typically used in fiber-to-the-home applications where it is desirable to place each physical switch port into a different VLAN for security purposes.

Switch Port Configuration

Figure 18. The Switch Port Configuration Menu

This menu is used to select and then configure the required ports. The first element highlighted in the menu is the Group ID. The switch is divided into 3 groups:-

• A = Ports 1-12,

• B = Ports 13-24,

• C = The 2 option slots (ports 25 and 26).

Use the <space> key to toggle between the different port groups. Alternatively, you can move to different groups by using the Prev Page and Next Page fields at the bottom of the screen. Highlight the required switch port by using the <Tab> or cursor key to move through the port list of the selected group. Select the port by using the <CR> or Return key. This action opens a new sub-menu that allows the specified port to be configured.

24 Port SNMP Managed Switch – User Manual Page 21

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Switch Port Configuration – Sub-Menu

In the port configuration screen (see page…) you can configure the port variables including:-

• Admin. State. This control enables or disables the port. Use the <space> key to toggle the enable/disable state.

• Speed and Duplex. This control allows selection of the port speed and duplex modes. There are 5 different options available and selected by using the <space> bar:-

o Auto-negotiation, o Half Duplex – 10Mbps, o Half Duplex – 100Mbps, o Full Duplex – 10Mbps, o Half Duplex – 100Mbps.

• Flow control is normally enabled but can be disabled using the <space> key if required.

•

• Per-Port Priority allows the basic priority of flow through the port to be controlled in

4 levels (Lowest, Low, Medium and High). Note that this port level priority control is over-ridden by the QoS (quality of Service settings in the Switch Configuration Menu.

•

• TX Bandwidth Provisioning and RX Bandwidth Provisioning allows the

bandwidth in each direction of transmission to be independently controlled. This function can be used to offer different levels of network bandwidth to customers so that creative tariff structures can be implemented. There are 9 levels of bandwidth available and the actual throughput is very dependant on the packet size. The throughput values below were based on 64 byte packets:-

o Level 1 = 4% o Level 2 = 8% o Level 3 = 12% o Level 4 = 16% o Level 5 = 33% o Level 6 = 50% o Level 7 = 80% o Level 7 = 88% o Full Bandwidth = 100%

• Default Port VLAN ID is the VLAN ID tag that is applied to untagged traffic when arriving into the switch from a switch port. This allows untagged traffic to be successfully routed through the switch. The default VLAN ID is set at 1

Permanent Address Configuration

This mode enables the switch to be configured to a high security mode where specified MAC addresses are associated with a port. These MAC addresses are programmed into the switch into static tables for use both in unicast and multicast applications. The switch can be configured to forward packets from a MAC address or reject packets to a MAC address. Up to 128 static MAC addresses can be added to the unicast table and 32 addresses to the multicast table. The required table is highlighted using the <Tab> key or the cursor keys and selected using the <CR> return key.

Figure 3-18. The Permanent Address Configuration menu

Static Unicast Address Configuration

You can create, modify, or delete a Static Unicast Address by selecting an index from the next menu and then by selecting entries from the following screen.

24 Port SNMP Managed Switch – User Manual Page 23

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Enter the MAC address of a device you wish to set as static unicast address associated with a switch port. Use<Space Bar> to toggle the status field between Disable, Forwarding, FilterIn, and Filter-Out.

• Disable – This Unicast Address entry has no effect to the switch system.

• Forwarding – All packets designated to this MAC address will be forward (and only to)

the designated port.

• Filter-in – Only packets originated from this MAC address will be permitted to enter this port, in other words, packets originated from any other MAC address will be dropped at this port automatically.

• Filter-out – All packets designated to this MAC address will be blocked

Due to menu restrictions, the following points apply:-

• The MAC address needs to be manually entered and cannot be acquired by learning the MAC address from a port or switch table.

• Only one static table entry at a time can be entered. It is necessary to go back to the table view to select the next entry for editing.

Static Multicast Address Configuration

In the Static Multicast Configuration Menu screen, besides the MAC Address and Status field (Enable/Disable), you can add member(s) to the group by checking the port(s) with <Space Bar> key. Up to 32 multicast groups can be supported by the switch.

Port Statistics

Figure 19. The Port Statistics menu

The required port is selected by entering the port number inserted in the Port ID field or by navigating to the Prev Port or Next Port fields and using the <CR> key to decrement or increment the port value. All counters for the selected port are reset by the Reset Counter control at the bottom of the screen.

Spanning Tree Protocol Configuration

When switches are used in more complex enterprise environments where redundant links may be required for resilience, then the switches need to be configured with the Spanning Tree Protocol. The Spanning Tree Protocol (STP) helps prevent network loops that would otherwise compromise the network. The STP configuration is done at both the switch and port levels. This high level menu controls the overall STP function of the switch.

Figure 20. The Spanning Tree Protocol Configuration menu

Note that Spanning Tree Enable Status needs to be set to <Enabled> to allow the switch to participate in Dynamic VLANs, see page 27 for details.

Use the cursor or <Tab> key to highlight the STP Enable Status field and toggle the mode using the <space> bar. The next 2 fields to modify are the Bridge Priority and the Bridge timings. A high Bridge Priority number gives greater priority to the switch in the STP negotiations. Note that you can abandon this menu screen without applying any changes by using the <Esc> key and then confirming with the <Enter> key.

Spanning Tree Protocol Port Configuration

Figure 21. The Spanning Tree Protocol Port Configuration menu

24 Port SNMP Managed Switch – User Manual Page 25

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

The Spanning Tree Protocol is applied to specific ports using this menu. In this screen you can assign spanning priority and path cost to any port(s). A port with higher priority, lower path cost is less likely to be blocked if Spanning Tree Protocol detects a network loop. The status fields offer helpful debug information when configuring or maintaining networks using STP:-

• The STP Port State field displays the status of the port and the values can be Forwarding, Blocking, Listening.

• The role of STP Port field displays the current role of the port in the Spanning Tree negotiations. These roles include Disconnected Port, Blocked Port, STP Enable, Root Bridge, Leaf Bridge.

Port-Based VLAN Configuration

This is the simplest but most insecure method of VLAN implementation. The physical ports are associated with specific VLANs so the integrity of the VLAN is dependant on the LAN connections being made to the correct ports. However, Port Based VLANs are very simple to implement and give control over broadcasts and allow the network manager to directly control the network. Each port can only be in 1 port based VLAN. Ensure that Port Based VLANs mode was selected in the Switch Device Configuration menu. If the port based mode was not selected, then the status line in the Port Based VLAN Configuration menu will show Port Based VLAN : Disabled

Figure 22. The Port Based VLAN Configuration menu

24 Port SNMP Managed Switch – User Manual Page 26

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Select the VLAN entry to create, modify, or delete the VLAN group. Use <Space Bar> to check (join) port(s) to the VLAN group.

Static VLAN Configuration

This mode is used to manually specify the ports that a VLAN has in its member set. This is achieved by manually editing the filtering database as shown below. This mode is useful on ports where the configuration is fixed or where the network manager wants to establish an administrative boundary outside of which any GVRP dynamic VLAN registration information is ignored. Ensure that the IEEE802.1Q VLAN mode was selected in the Switch Device Configuration menu. If the IEEE802.1Q static VLAN mode was not selected, then the status line in the Static VLAN Configuration menu will show Static VLAN : Disabled The first screen shows the currently selected VLAN sorted by an internal index number. Select the VLAN entry to create, modify, or delete and proceed to the next screen.

To modify the settings of the Static VLAN filtering database, select the VLAN and then apply the settings to each of the required ports. The settings are:-

• ( ) – Dynamic Configuration only. The selected port is available for dynamic VLAN registration and configuration only,

• (F) – Static Configuration only. The selected port is a static member of the VLAN and cannot be removed by the dynamic VLAN registration process.

• (B) – The port is inhibited from being a static or dynamic member of this VLAN.

•

Use the <space> bar to toggle between the setting values. After the VLAN entry has been made, save the settings, exit the menu and view the Static VLAN Configuration menu (Figure

23) to verify that the required changes have been made.

Dynamic VLAN Configuration

This mode enables the switch to negotiate with other VLAN enabled switches in the network to create and update VLAN registration entries using open standards GVRP.

In the Switch Device Configuration menu, ensure that the following modes are selected:-

• Spanning Tree Enable State

• VLAN Mode Configuration

<IEEE802.1Q VLAN>

• GVRP Enable State

If the correct modes are not activated, then the Dynamic VLAN Table menu status line will show Dynamic VLAN : Disabled The first screen shows the currently selected VLAN sorted by an internal index number. Select the VLAN entry to create, modify, or delete and proceed to the next screen.

Figure 25. The Dynamic VLAN Table menu

This summary screen displays the VLAN mapping for port(s) that can join the VLAN(s) through Dynamic VLAN Registration.

VLAN Untagged Configuration – Port Untagged Configuration

Figure 26. The Port Untag Configuration menu

The switch sets all ports by default as <Untagged>. This means that VLAN tags are stripped off at the egress port. To change the selected port to <Tagged>, use the <Space Bar> to uncheck ( ) the port(s) from the Port Map.

GARP Configuration

Figure 27. The GARP Configuration menu

GARP (Generic Attribute Registration Protocol) defines the operation of the registration and de-registration of attribute values on a per-port basis. It allows dynamic filter entries for VLAN membership to be distributed among the Forwarding Databases of VLAN-aware switches. By joining GVRP VLAN information can be automatically applied to a switch without the need for local configuration on VLANs. The rule of the aging scheme is: GARP Leave All Time > GARP Leave Time > GARP Join Time

MTU/MDU Per-Port VLAN Table

When the switch is used in a multi-dwelling or multi-tenanted unit, then it can be useful to put some tenants on one uplink and the remaining tenants on another uplink. This read-only table shows the port mapping automatically assigned by the switch. The switch uses either 1 or 2 uplinks ports for the MTU/MDU VLANs. The number of uplinks is specified in the Switch Device Configuration menu. For this automatically assigned MTU/MDU Per-Port VLAN mode to be active, ensure that the following settings are selected in the Switch Device Configuration menu:-

• VLAN Mode Configuration

< MTU/MDU Port LAN >

• GVRP Enable State

The switch maps either all ports to a selected uplink (port 26 ) or maps Ports 1-12 to uplink port 25 and Ports 13-24 to uplink port 26. It is not possible to map specific ports to specific uplinks.

IGMP Snooping Table

By supporting IGMP (Internet Group Management Protocol) Snooping, the switch can forward multicast traffic intelligently. Packets are only forwarded to the ports that belong to the multicast group instead of being broadcast to all ports and possibly disrupting network performance.

Figure 29. The IGMP Snooping Table

This lookup table lists each of the multicast groups present in the switch and shows the associated port map. Up to 32 multicast groups are supported.

24 Port SNMP Managed Switch – User Manual Page 31

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Trunk Group Configuration

The switch supports trunk groups between switches. This scheme combines ports to become an aggregate link to increase the bandwidth available between switches using the standard IEEE802.1ad. Up to 8 ports can be assigned to a trunk and the switch supports up to 4 trunks.

Figure 30. The Trunk Configuration Menu

The menu offers the 4 trunk groups and these groups are associated with specific ports. For example, Trunk Group 1 can be configured to use 2, 4 or 8 ports that use the physical ports 12 or 1-4 or 1-8 respectively. The required number of ports in the trunk is selected by highlighting the Group x Aggregated Ports field and using the <space> bar to view the 2. 4 and 8 port options. Select the required value using the <CR> or return key. To activate the group, navigate to the Trunk Group x Status field and toggle between the <Enable> and <Disable> states.

Note that all the ports in the trunk group must run at the same speed, therefore it is not possible to mix Gigabit and 10/100Mbit/s ports in the same trunk link.

24 Port SNMP Managed Switch – User Manual Page 32

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Port Mirroring Configuration

Port mirroring is used during more complex diagnostic operations to allow network analyzer devices such as Sniffer systems to view live network traffic. This function is needed on switches as packets are normally forward only on MAC address values and therefore do not get sent to other ports. Port mirroring allows the engineer to program the switch to output traffic that is being sent to or from a designated port to a debug or mirrored port.

Select the Port Mirroring Configuration menu and use the <tab> or cursor keys to move to the Source Port field. Highlight the required Source Port by using the <space> bar and select the value using the <CR> or return key. Then select the Target Port in the same way. Save the settings. The Source and Target Ports must have different port numbers. Note that bandwidth constraints mean that packet loss will occur if the Source Port has a higher traffic level than can be supported by the Target Port. For example, selecting Gigabit 1 as the source and 10/100M port 3 as the target will probably result in overload as port 3 will not be able to handle all the packets arriving from the Gigabit port.

Figure 31. The Port Mirroring Configuration Menu

User Authentication

Access to the switch is controlled by a username and password screen that is used when logging into the switch, see page 12 for details. This helps to ensure that only authorized users can view or modify the switch settings.

This menu enables the access rights to the switch to be set. The level of access is determined by the Access to the switch is by a password protected menu which allows either high level Read/Write or low level Read Only. The switch is supplied with the following default user/password combinations:Read/Write Access:-

• Username

root

• Password

root

Where < > is a blank field so just enter the <CR> or return key.

Read Only Access:-

• Username

guest

• Password

< >

Where < > is a blank field so just enter the <CR> or return key.

Figure 32. The User Authentication Menu

You can change the password setting as in the user authentication menu. You can also create user and assign different privilege to suit your needs.

The menu enables the root level user to assign different passwords and different user names.

24 Port SNMP Managed Switch – User Manual Page 34

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Note that the user name and password are stored as encrypted data within the switch and so it is not possible to recover these values in the field. This means that great care must be taken to ensure that the user name and password values are safely stored in a secure location. If you are changing passwords, then it is strongly recommended that you create a second Read/Write level privilege setting for another user name so that if the root password is lost, then the switch can be accessed using the second Read/Write user name and password.

Figure 33. Modifying the User Authentication Setting

After selecting an entry to add or modify, type in user name and password, toggle the user privilege with <Space Bar> and then save the changes to using the Update control. Ensure that these user name and values are stored in a secure location.

System Utility

This menu is used to perform a range of system level functions including restarts, updating switch firmware and resetting the factory default values.

Figure 34.System Utility Menu

System Restart

Figure 35. The System Restart Menu

This menu option allows the switch to be restarted through either a <Cold Start> or a <Warm Start>. A cold restart results in the switch implementing a full Power-On Self Test and so this takes more time to boot. A warm restart process bypasses the Power On Self Test. Note that when the IP address values have been changed, then it is essential that the switch be restarted to ensure that the correct values are placed in the Non-Volatile Memory (NVRAM).

24 Port SNMP Managed Switch – User Manual Page 36

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Factory Reset

This mode allows selective restoration of parts of the switch to their factory default settings. This selective resetting is very useful in debugging network or switch problems when it is required to reset specific part of the switch such as VLANs etc.

Figure 36. The Factory Reset Menu

The menu allows the resetting of single or multiple parts of the switch. Note that resetting the Network Configuration will reset the switch IP address and so this option needs to be used with care, especially if managing the switch over the LAN.

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

System Download

In some cases, the switch firmware may need to be upgraded to add features or to correct problems etc. New firmware can be downloaded from a TFTP server to the switch. To enable this download to occur, load the new firmware image onto the TFTP server, enter the IP address of the switch and select the image file to be downloaded. In the System Download menu, enter the IP address of the TFTP server and select the type of code image being provided (Boot ROM or System Software). Then save the settings and select the <Start Download> field.

Figure 38. The System Download Menu

The download time is dependant on network speed and the size of the image file. The TFTP server will report the success/failure status of the download. Note that after a download, the switch will restart and this can impact network traffic.

System Quick Start

This allows the start up procedure to by-pass some of the test that are carried out during initiation of the switch and so allows the switch to start up quicker than “Cold” or “Warm” boot.

Configuration Update Setting

This mode saves the full settings of the switch into non-volatile memory. It is recommended that this control is used when the switch has been programmed. This will ensure that the full configuration will be restored when the switch is powered up.

Trunk Group menu

Figure 49. The Trunk Group sub-menu within Switch Port Configuration

Port trunking is the ability to group several ports to increase the aggregate bandwidth between this switch and another compatible switch. This is an inexpensive way to increase bandwidth between switch or routers. The switch can support up to 4 trunk groups with the aggregation complying with the standard IEEE802.1ad, which enables inter-operation of switches from different vendors. See The Trunk Configuration Menu on page 31 for details.

Port Mirror menu

Figure 50. The Port Mirror sub-menu within Switch Port Configuration

Port Mirror will send all frames from a specific port to a target port. This can be used to assist in the location of network errors or erroneous packet transfers without interrupting the flow of data across the network. To configure the port mirroring mechanism:-

• Choose the monitored port in " Source Port "

• Choose the corresponding target module, port in “Target Port" choice box.

• Click the corresponding "Enabled" check box.

Permanent Address Configuration

Figure 51. The Static Unicast Address in Permanent Address Configuration

This Permanent Address menu has 2 sub-menus:-

• Static Unicast Address

• Static Multicast Address

You can Add, modify, or delete Static Unicast Address by selecting entries from the following screen.

Enter the MAC address of a connected device you wish to set as static unicast address for the associated switch port. Select the status field between Disable, Forwarding, Filter-In, and Filter-Out.

• Disable – This Unicast Address entry has no effect to the switch system.

• Forwarding – All packets designated to this MAC address will be forwarded to (and

only to) the designated port.

• Filter-in – Only packets originated from this MAC address will be permitted to enter this port, in other words, packets originated from other MAC address will be dropped at this port automatically.

• Filter-out – All packets designated to this MAC address will be blocked (the port is disregard here).

Due to menu restrictions, the following points apply:-

• The MAC address needs to be manually entered and cannot be acquired by learning the MAC address from a port or switch table.

• Only one static table entry at a time can be entered. It is necessary to go back to the table view to select the next entry for editing.

24 Port SNMP Managed Switch – User Manual Page 46

Product Number 0-1591058-x © Tyco Electronics 2003 PL0351 Issue 1

Static Multicast Address Configuration

In the Static Multicast Configuration Menu screen, you can associate ports with multicast groups. Up to 32 multicast groups can be supported by the switch. To add a new static group to the switch, use the Add button and enter the multicast address. Exit the menu using the Submit button.

• Click the Add button at the bottom of the screen,

• Enter an index number for local usage only,

• Enter the Multicast MAC address. Note that these addresses must be within specific

bounds,

• Click the ports that are to be associated with the multicast,

• Enter a description if required,

• Enable the static multicast mode if required,

• Click the Submit button,

• Click the Static Multicast Address hyperlink to view a map of the port/multicast

settings.

See Static Unicast Address Configuration on page 22 for details.

Spanning Tree Protocol Configuration

Spanning tree is a link management protocol that provides path redundancy while preventing undesirable loops in the network. For Layer 2 Ethernet network to function properly, only one active path must exist between two stations. The spanning-tree algorithm calculates the best loop-free path throughout a switched network. STP forces redundant data paths into a standby (blocked) state. If a network segment in the spanning tree fails and a redundant path exists, the STP algorithm recalculates the spanning tree topology and activates the standby path. The unit provides a switch level menu and a port level menu.

Figure 52. The Switch level Spanning Tree Protocol Configuration - upper

If you enable the spanning tree protocol, you must complete the Bridge Priority and Time fields with appropriate value.

24 Port SNMP Managed Switch – User Manual Page 47

Figure 53. The Switch level Spanning Tree Protocol Configuration - lower

Spanning Tree Protocol Port Configuration

After the switch level variables have been configured, then the port level values should be set. This is implemented in the Spanning Tree Protocol Port Configuration menu.

Figure 54. Spanning Tree Protocol Port Configuration - Upper Menu

In this upper and lower menu, you can assign spanning priority and path cost to any port(s). A port with higher priority, lower path cost is less likely to be blocked if the Spanning Tree Protocol is detecting a network loop.

24 Port SNMP Managed Switch – User Manual Page 48

Figure 55. Spanning Tree Protocol Port Configuration - Lower Menu

See Spanning Tree Protocol Port Configuration on page 24 for details.

Port Statistics

Figure 56. The Port Statistics Menu

You can view the port statistics information by either entering the port number in the Port Number field or using the pull-down list from that field. The default update Interval is set at Suspend which is a one-shot view of the counters that is not updated. To see an automatically updating display, select the required rate in the Update Interval field and click the Submit button. The rate of 2 seconds provides an effective image of the port statistics. The counters can be reset by using the Reset Counters button. This reset control only clears the statistics for the selected port.

24 Port SNMP Managed Switch – User Manual Page 49

VLAN Configuration

The switch supports a range of VLANs that can be configured using three sub-menus:-

• Static VLAN Configuration

• MTU/MDU Port VLAN Configuration

• Port Based VLAN Configuration

The default view is the Static VLAN Configuration and other 2 sub-menus are selected using the section links across the top of the pane. See page 26 for details of the different VLAN modes and programming the modes using the console mechanism.

Figure 57. The Static VLAN Configuration Menu

The Static VLAN Configuration Menu is activated when using IEEE802.1Q VLANs. This menu is not relevant in either port-based or the MTU/MDU VLAN modes. To add Static VLANs, set the Index value (for local use only), the VLAN ID and then from the table of ports select the VLAN attributes for the port:-

• Normal = The selected port is available for dynamic VLAN registration and configuration only,

• Fixed = Static Configuration only. The selected port is a static member of the VLAN and cannot be removed by the dynamic VLAN registration process.

• Forbidden = The port is inhibited from being a static or dynamic member of this VLAN.

After the ports have been configured in the required modes, the settings can be saved by clicking the Submit button. When the VLAN is to be put into service, use the Status pull-down box to Enable the VLAN with its set attributes. Activate the setting by using the Submit button.

24 Port SNMP Managed Switch – User Manual Page 50

The mapping of the VLAN will be shown in the display with the following values against each port number.:-

• (S) – Port(s) is set as static (fixed) member of the VLAN.

• (D) – Port(s) is set as static (fixed) member of the VLAN and can be registered as a

dynamic VLAN member as well.

• (C) – Port(s) is both a static member and a dynamic member of the VLAN. (Common when GARP is enabled)

To view the settings of all ports in the switch, select the VLAN Configuration link in the left hand navigation pane and a summary of each VLAN will be displayed.

When there are mixed environments of tagged and un-tagged ports in the switch, then it is necessary to designate ports as handling tagged traffic. This is because, by default the switch has every port in the un-tagged mode and so to allow tagged traffic, the specific port needs to have its attributes changed. This is achieved by selecting the Untagged Configuration menu in the Static IEEE802.1Q VLAN page and if a port is to carry tagged traffic, use the pull-down box to change from Yes to No. This will ensure that the port can handle tagged traffic.

Figure 58. The Untagged Configuration Menu

If the port selection is Yes, then the port will strip off VLAN tags. If the port selection is No, then the port will forward VLAN tags.

24 Port SNMP Managed Switch – User Manual Page 51

MTU/MDU Per-Port VLAN

This is a special mode that places each switch port into a separate VLAN with downlink Ports 1-24 forwarded to either 1 or 2 uplink Ports. This is intended purely for applications where the security constraints are that downlink switch ports RJ-45 ports must never be allowed to communicate, for example in Multi-Tenanted buildings.

Figure 59. The MTU/MDU Per Port VLAN Table in The VLAN Configuration

No adjustments are possible to this special VLAN configuration and the paths are fixed by the MTU/MDU selection made in the Switch Configuration menu > VLAN Mode Configuration. After the MTU/MDU mode has been selected and the Submit button pressed, a similar menu is displayed that offers MTU/MDU Per-Port VLAN either with 1 or 2 uplinks from a pull-down box. If <One Uplink> is selected then ports 1-24 will be mapped to the uplink port 25. If <Two Uplinks> are selected, then ports 1-12 are mapped to uplink port 25 and ports 13-24 are mapped to uplink 26. Ensure that the Submit button is clicked after the uplink number selection.

24 Port SNMP Managed Switch – User Manual Page 52

Port Based VLAN Configuration

This menu is accessed VLAN Configuration menu and is used to set the port based VLAN mapping for the switch. In this case, the VLANs purely provide an access link that does not support tagged VLAN traffic. Select Port Based VLANs from the pull-down list in the Switch Configuration > VLAN Mode Configuration box. Click the Submit button at the bottom of the Switch Configuration page to save the setting. Select VLAN Configuration and then Port Based VLAN Configuration to view the page below:-

Figure 60. The Port Based VLAN Configuration Menu

Add a VLAN by clicking the Add button at the bottom of the page, enter the VLAN name (for local reference only), then select the registration state of the port (Yes to register the port and No to de-register the port as a member of the VLAN). If the VLAN is to be placed into service, then select Enable from the Status box. Click the Submit button at the bottom of the page to save the settings.

To modify or delete a VLAN, use the mouse to click on the map display of the required VLAN. This highlights the line in both panes of the display. Notes:-

1. There is no acknowledgment after the Delete button is pressed, so the action is irreversible.

2. The switch allows the creation of different Port Based VLANs sharing the same physical ports. This is not a valid combination as only 1 VLAN should be assigned to a physical port.

24 Port SNMP Managed Switch – User Manual Page 53

GARP Configuration

GARP (Generic Attribute Registration Protocol) defines the architecture, rules of operation, state machines and variables for the registration and de-registration of attribute values. It allows dynamic filter entries for VLAN membership to be distributed among the Forwarding Databases of VLAN-aware switches. This screen allows the GARP attributes to be defined on a per-port basis.

Figure 61. The GARP Configuration Menu

By joining GARP VLAN Registration Protocol, VLAN information is actively maintained across the network. The rule of the GARP aging scheme is:

GARP Leave All Time > GARP Leave Time > GARP Join Time

24 Port SNMP Managed Switch – User Manual Page 54

IGMP Configuration

Multicasting is used to support real-time applications such as video conferencing or streaming audio. IGMP (Internet Group Multicast Protocol) allows you to query for any attached hosts who want to receive a specific multicast service. The switch looks up the IP Multicast Group used for this service and adds any port, which received a similar request to that group. It then propagates the service request on to any neighboring multicast switch to ensure that it will continue to receive the multicast service.

Figure 62. The IGMP Configuration Menu

By supporting IGMP (Internet Group Management Protocol) Snooping, the switch can forward multicast traffic intelligently. Packets are forwarded to the ports that belong to the multicast group instead of being broadcast to all ports and possibly disrupting network performance. This lookup table reflects the multicast group(s) configuration of your system and provides an overview of the port(s) map to each multicast group. Up to 32 multicast groups are supported by the switch.

User Authentication

You can change the password setting in the user authentication menu. You can also create user and assign different privilege to suit your needs. After selecting an entry to add or modify, type in the user name and password, toggle the user privilege and then update the changes.

Figure 63. The User Authentication Menu

Ensure that the root Read/Write level password is kept secure and note the cautions detailed on page 33.

24 Port SNMP Managed Switch – User Manual Page 55

System Utility Menu

System Restart

This menu allows the switch to be restarted if required. Either a Warm Start or a Cold Start can be selected. See page 35 for further information.

Figure 64. The System Restart Menu

Note that you need to perform either a Cold Start or Warm Start to have the changes made saved in non-volatile memory.

Factory Reset

Figure 65. The Factory Reset Menu

All selections in this menu are independent and allow selective restoration to meet specific requirements. This allows individual sections to have their default settings restored without effecting the settings that apply to other switch settings.

24 Port SNMP Managed Switch – User Manual Page 56

The automatic log-out time for the Telnet and Local Console displays can be set to specific values for security purposes. If the value is 0, then there is no timeout specified for the interface. Note that this is potentially a bad idea as security can be compromised.

Figure 66. The Login Timeout Interval Menu

System Download

This menu allows the download of new firmware images to the switch so that bugs can be fixed and enhancements added. The download is via TFTP and you can select to load the required Boot or System Software elements. Instructions for the upgrade including file names will be provided. See page 37 for more information.

Figure 67. The System Download Menu

24 Port SNMP Managed Switch – User Manual Page 57

Update Setting

This menu option saves the state of the switch into non-volatile memory. This enables the switch to be powered off and then recover with the original setting. It is recommended that this option be used to ensure that switch and network settings are retained.

Figure 68. The Update Setting Menu

Option Modules

The switch has 2 uplink module ports that can support a range of interfaces that are used to connect to the network backbone etc. The switch can support up to two of the following single port modules, which can be used in any combination:

• 10/100/1000Mbps Auto-MDI/MDI-X RJ-45 module

• 1000Base-SX multimode fiber module

• 1000Base-LX singlemode fiber module

• 100Base-FX SC multimode fiber module

• 100Base-FX MT-RJ multimode fiber module

• 100Base-FX SC singlemode fiber module

Installation of the Modules

The modules are easy to install following the procedure:-

1. Determine which module slot is to be used.

2. Power-off the switch.

3. Remove the cover of the required uplink port and retain the 2 screws and cover.

4. Fit the required module into the slot and carefully slide the module home until the front plate is in line with the switch front panel.
