3.3 Management from CNM

English

In Part 3, start the CNM program and manage the switch to meet your
network requirements. Before starting CNM, make sure that your manage
station is attached to the same network as the switch is. Otherwise, CNM will
not be able to discover the switch.

Note: This version of CNM only manages the switches in the same
network.

3.3.1 Switch Discovery and Management

1. Make sure that the switch is powered ON and that the CNM is installed on
the management station.

2. Click on the CNM shortcut icon in the desktop of the manage station to start
the CNM application. CNM will display a window as shown in Figure 3.2

Figure 3.2. CNM Outlook

3. Select the proper NIC at the same network with the switch, then click on the

Discovery icon in the tool bar. After the discovery is done, the left frame of
the window will show the MAC addresses of the switches discovered by the
CNM as Figure 3.3.

English

Figure 3.3. Available Switches

4. Select the switch you want to manage by clicking on the MAC address, then
you can start to configure the switch by CNM.

5. If the CNM cannot discover the switch you want to manage, please repeat
step 1 to 4 again.

Note: The switch must be powered on and connect to your network before
starting the CNM.

GigaX Centralized Network Management User’s Manual 13

English

3.3.2 Password Recovery

The switch is protected by a password. The password is required to make
CNM able to manage the switch. Once the password is lost, you need to
reset the password back to factory default password, which is 0x2379. The
password is four digit long, could be change through CNM.

1.Prepare one Cat-5 cable and unplug all the cables in the switch ports.

2.Power off the switch, then power it on. Within 20 seconds after power
on, plug the Cat-5 cable to port 3 and 4. That is, make a loop by port 3
and 4. The password will reset to default value.

3.Remain the loop about 1 minute to let the password reset happen.

4.Unplug the cable, then power cycle the switch. You can manage the
switch by default password.

Note: To reset the password, there must be no connection in the switch
except the loop between port 3 and 4.

3.3.3 Factory Default Setting

You can reset the switch configuration back to factory default value by the
similar steps as the password recovery. Instead of looping port 3 and 4, use
port 1 and 2 to make a loop.

1.Prepare one Cat-5 cable and unplug all the cables in the switch ports.

2.Power off the switch, then power it on. Within 20 seconds after power
on, plug the Cat-5 cable to port 1 and 2. That is, make a loop by port 1
and 2. The configuration will reset to factory default value.

3.Remain the loop about 1 minute to let the configuration reset happen.

4.Unplug the cable, then power cycle the switch. You can manage the
switch by default password and the switch configuration is back to
factory default.

5. Add Switch: add a switch to the topology tree manually. A window pops out

for this purpose as Figure 4.6. Select the network adapter you want the
switch to attach to, give the switch MAC and name, and an authentication
key as the password if you don’t use the default one (2379), then click OK to
finish the action. However, a manually added switch does not mean it can be
configured or discovered by CNM. The function provides a way to add a
known switch to topology list once the CNM cannot discover the switch.
There is a tool bar button for it..

English

Figure 4.6. Add Switch

6. Remove Switch: you can remove any switch in the topology list manually

through this function. It pops out a switch list and check those switches you
want to remove. Please refer to Figure 4.7 for the switch list window.

Figure 4.7. Remove Switch

7. Load: load a topology list from a file. There is a tool bar button for it.

8. Save Topology: save the current topology list to a file. There is a tool bar

button for it.

9. Save As: specify a file name to save the topology list

10. Exit: exit from CNM program

4.3.2 Setup

Figure 4.8. Setup

CNM polls the switch status periodically, the polling interval can be adjusted.

1. Auto Update Time Interval: as Figure 4.9, a proper value can be
set. The auto update time interval is used to poll the switch statistics
and link status on the top of the window. The interval value could be
adjusted from 0 to 300 seconds. 0 means no polling at all. There is a
tool bar button for it.

4.4 Switch Topology

The switch topology frame is on the left part of the CNM window. It shows
the discovered switches and the relationship among them. Each presents a
NIC interface. The interface name and MAC address is shown after the.

The switch topology shows the relationship among the switches in a tree
view. That is, if a switch A has connections to switch B and your NIC, then a
cascade tree will display as Figure 4.10.

English

Figure 4.10. Switch Relationship

In this way, you can find the relationship among the switch. It helps design
and debug your network. Each is a switch with name and MAC address
followed. You can assign a name to the switch by click the right button on the
mouse while the mouse is point to the switch MAC address.

Note: All the switch names are kept in CNM file, but not in the switches. So if
you use CNM to manage the same switch on another management station,
the name may be different because the switch does not keep its name.

4.4.1 Topology Discovery

The topology discovery is done by user’s request. That is, no auto update is
executed for the topology change. This will reduce the network traffics since
the discovery generates some packets to query the switches.

GigaX Centralized Network Management User’s Manual 21

English

4.4.2 Switch Add and Removal

Discovery action will create the topology tree by all the discovered switches.
The default password will be used in the discovery process. Sometimes you
may have a switch with another password that is different from the default
one. In this case, the switch cannot be discovered by the default password.
You need to add a switch to the topology manually.

Figure 4.11 shows the window to add a switch. The are a couple of columns
to fill to add a switch successfully.

Figure 4.11. Add Switch

1. Adapter: select the corresponding adapter to add a switch under it.

2. Switch: check the box if you want the new switch to be added under a

specified switch in the topology tree. The manually added switch will be
moved to a right place to show the relationships in the topology after a
successful discovery.

3. MAC: the most important information is the MAC address. If the MAC is
wrong, the new added switch can not be accessed by CNM.

4. Name: a good name may remind you something about the switch. However,
the switch name is good only in the same CNM file. So the name may not be
unique when you use different CNM files to do discover.

22 GigaX Centralized Network Management User’s Manual

Once a switch is added to the topology tree, you can find it in the
corresponding place. You have to left click the switch symbol to switch the
current status/configuration window from other switch to this switch. If the
communication is good, you can see the linking status window on the right
frame of the CNM window , and the topology tree will display the switch
symbol in a correct place to show the relationship. If CNM cannot discover

English

the manually added switch, then a

will attach to the switch to show it is

not reachable to the CNM.
Figure 4.12 shows the window to remove switches, just check the box before

the switch to select those you want to remove, click the remove icon to start
the action. All the corresponding switches will be removed and the tree
branch after the removed switches are moved up to under the adapter . A
discovery action will update the topology tree for the current network. You
may find the removed switches are back to the topology tree because they
are discovered again.

Figure 4.12. Remove Switch

Note: The removed switch may be added back to the topology tree
because the discovery action finds the switch in the network. This is
normal because the switch is still working.

4.4.3 Topology Load and Save

A topology can be saved for later reference. The CNM starts with a default
topology file. After the discovery action, it shows the update network
topology. You can save it in a good file name and load it when you need it.

GigaX Centralized Network Management User’s Manual 23

4.5 Switch Setup

English

Before using the configuration windows, it is better to know following buttons
or icons because they are used throughout the setup. The following table
describes the function for each button or icon.

Table 4.1 2. Description of Commonly Used Buttons and Icons

Button/Icon Function

Hint: Clicking the Apply button can only save the configuration
temporarily, users need to select “Apply and Save” from “Topology” drop­down menu in order to save the configuration permanently.

Before starting any new configuration, it is always recommended to reload
the current switch configuration. This will help you know what you are going
to change and the communication between CNM and the switch is good.

There is a message bar on the bottom showing the NIC’s MAC and the
switch MAC you are working on. Check these information before applying
any new configuration to prevent an improper settings.

Note: Check the message bar on the bottom to make sure you are working
on the proper switch before any configuration set up.

4.6 System

There are reboot, link status and change password under the system menu.

4.6.1 Reboot

The 1024P provides hardware and software reset as shown in figure 4.13.
Hardware reset is to reset the system at a initial state like the process of
power on hardware reset.

Note: Hardware reset will clear all current settings if you do not save the
configuration.

The software reset will rest the system to the initial state and start the port
link negotiations, but the MAC table, VLAN table data, and current
configuration will be kept.

4.6.3 Change Password

A valid password consists of 4 digits, from 0 to 9, and a to f. The
authenticator does not check upper case or lower case. For example,
password “12ab” is treated as “12AB”. Once the password gets changed,
CNM will use the password to retrieve the information about the switch.

If the password is forgotten, please refer to 3.3.2 to reset the password in the
switch. After it, you have to remove the switch from the topology and
discover the switch again.

After changing the password, CNM will show a dialog box for administrators
to save the topology or not. If not, administrators will have to do two jobs
when CNM starts up next time. First, manually add the switch according to
section 4.4.2. Second, change password again and replace 0x2379 with
correct one.

English

4.7 Configuration

The Configuration menu provides the configuration for all the functions that
the switch can supports, like physical interface, link aggregation, bandwidth
control, traffic control, VLAN, IGMP snooping and QoS.

To keep all the new configurations and save the bandwidth for
communications, each configuration page will not retrieve information from
switch until you click the Reload button. In some configuration pages, you
can select the ports to reload the information from the switch.

4.7.1 Physical Interface

English

Figure 4.18. Physical Interface

Figure 4.18 shows the configuration for each port. Select the ports you want
to configure or reload information from the switch by clicking on the check
boxes in front of the ports, then click on Config to set the configuration for
the ports, or click on Reload to retrieve configuration from the switch, or click
on Apply to apply the new settings to the switch. Some settings you can do
to the physical interface

GigaX Centralized Network Management User’s Manual 31

English

1. Enable or disable a port

2. Speed and duplex mode. Select 1000 full-duplex on the Fast Ethernet ports
(from 1 to 24) will set the ports to 100 full-duplex mode.

3. Flow control - Back pressure flow control is used in half and full duplex
modes to prevent packet loss.

A software reset will be triggered after the configuration is apply. The
purpose of software reset is to restart link negotiations.

4.7.2 Link Aggregation

Figure 4.19. Link Aggregation

32 GigaX Centralized Network Management User’s Manual

Link aggregation creates new virtual links with more bandwidth. For
example, port 1 and 2 can work together as one link to another device. The
new virtual link has 200Mbps bandwidth. The switch provides 8 groups of
link aggregations shown on the top of figure 4.19.

Click on the Reload button to retrieve the configuration from switch. The
checked trunk group means this group has been activated. You can check
the trunk group to enable new trunk or uncheck the trunk group to disable
the trunks. Click on Apply to make them effective in the switch.

The Trunking Status shows the ports work as trunk ports currently. A green
light in the port means the port is working as trunk port properly, otherwise it
shows no light.

4.7.3 Bandwidth

English

Figure 4.20. Bandwidth Configuration

1024P provides TX/RX bandwidth control for each port. Please reload the
configuration before you start to set up new configuration. The page is
shown as figure 4.20.

Select the ports you want to configure, then select proper bandwidth for TX/
RX directions. Click on Apply to apply to the switch.

4.7.4 Traffic Control

Traffic control is to set the following items

1. Broadcast storm filtering control: if enabled, each port start to drop broadcast
packets after a continuous received broadcast packets count up to 64. It will
be back to normal if no more broadcast packet is received in 800ms or any
non-broadcast packet is received.

2. IP multicast packet flow control: if enabled, the system will drop IP
multicast packets under a congestion condition. Otherwise, the packet will
be forwarded to non-congested ports.

3. Broadcast packet flow control: if enable, the system will drop broadcast
packets under a congestion condition. Otherwise, the broadcast packet will
be forwarded to non-congested ports.

Again, please reload the settings from the switch before starting to do new
configurations.

4.7.5 VLAN Setup

A VLAN is simply a configured broadcast domain. An administrator applies
VLAN to separate a network. VLAN Setup provides administers abilities to
set up port-based and tag-based Vlan. The page is shown as figure 4.21.

An administrator could refer the following to add a VLAN

1. Choose VLAN type, port-based or tag-based VLAN.

2. Assign VLAN id, if you choose tag-based VLAN.

3. Click

4. Click Add VLan to add a Vlan, and then Vlan Table will show it.

5. Repeat step 1 through 4, if need to create another Vlan.

6. Click Apply and then Vlan configuration will take effect.

or to assign port members.

7. VLAN function: enable or disable the VLAN function.

8. Unicast packet inter-VLAN leaky: to enable the packet to be forwarded to a
destination port (L2 table hit) at different VLAN.

9. ARP broadcast packet inter-VLAN leaky: to enable ARP frame to broadcast
to all switch ports.

10. IP multicast packet inter-VLAN leaky: to enable IP multicast packet to be
flooded to all the multicast address group member set ignore the VLAN
member set domain limitation.

11. 802.1Q VLAN tag aware: to enable tag-based VLAN function.

12. Ingress rule for acceptable frame types: to admit all frames or to admin only
VLAN-tagged frames.

13. Ingress rule for ingress filtering: to enable filter the frame received from a
port which port is not included in the classified VLAN group member.

4.7.6 IGMP Snooping

Enable the IGMP snooping will let the switch learn the multicast router port
and group address member ports into the multicast address table. The table
is combined with L2 MAC table, so the maximum entry is 8K. The valid port
member will auto aging out after about 5 minute idle. Figure 4.23 shows the
page.

4.7.7 QoS Setup

The system support 2 level priority queues. The queue service rate is based
on the packet-based Weighted Round Robin algorithm. The ratio can be set
as 4:1, 8:1, 16:1, or strictly high priority first.

The port-based priority is to decide the packet priority by the receiving ports.
You can select the high priority ports from the switch graphic.

If TOS/DSCP based priority is enabled, it will be assigned to high priority
queue if the field value is:

expected forwarding: 0b1011 10;
assured forwarding: 0b001010, 0b010010, 0b01 1010, 0b100010
network control: 0b11x000

If 802.1p based priority is enabled, the packet forward priority is decided by
the CoS value. The high priority packets have the CoS value from 4 to 7.

In some situations, you may want the high priority packets to get forwarded
even the 802.3x flow control stop transmitting packets. In this case, enable
Adapted Flow Control will turn off 802.3x flow control for a short time to let
the high priority packets get forwarded. The 802.3x is re-enable when no
high priority frames are received for 1 to 2 seconds.

4.8 Statistics

English

Statistics offer Port Traffic, Traffic History and Comparison charts. The
switch has 3 counters for 8 kinds of statistics. So you cannot see all the
statistics at the same time. That is, the old statistics data will be gone if you
start to use the counter for another statistics.
