Chapter 1: Switch Management

Configuration Options

For advanced management capability, the onboard management agent provides a
menu-driven system configuration program. This program can be accessed by a
direct connection to the serial port on the rear panel (out-of-band), or by a Telnet
connection over the network (in-band).

The management agent is based on SNMP (Simple Network Management
Protocol). This SNMP agent permits the switch to be managed from any PC in the
network using in-band management software.

The management agent also includes an embedded HTTP Web agent. This Web
agent can be accessed using a standard Web browser from any computer attached
to the network.

The system configuration program and the SNMP agent support management
functions such as:

• Enable/disable any port

• Set the communication mode for any port

• Configure SNMP parameters

• Add ports to network VLANs

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

Required Connections

Console Port (Out-of-Band) Connections

Attach a VT100 compatible terminal or a PC running a terminal emulation program
to the serial port on the switch’s rear panel. Use the null-modem cable provided with
this package, or use a null-modem connection that complies with the wiring
assignments shown in Appendix B of this guide.

When attaching to a PC, set terminal emulation type to VT100, specify the port used
by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit,
no parity, and 9600 bps (for initial configuration). Also be sure to set flow control to
“none.” (Refer to “Configuring the Serial Port” on page 2-13 for a complete
description of configuration options.)

Note: If the default settings for the management agent’s serial port have been

modified and you are having difficulty making a console connection, you can
display or modify the current settings using a Web browser as described under
“Configuring the Serial Port” on page 3-5.

1-1

Switch Management

In-Band Connections

Prior to accessing the switch’s onboard agent via a network connection, you must
first configure it with a valid IP address, subnet mask, and default gateway using an
out-of-band connection or the BOOTP protocol.

Note: By default BOOTP is disabled and the IP address is set to 192.168.10.1. See

“IP Configuration” on page 2-10.

After configuring the switch’s IP parameters, you can access the onboard
configuration program from anywhere within the attached network. The onboard
configuration program can be accessed using Telnet from any computer attached to
the network. The switch can also be managed by any computer using a Web
browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above), or
from a network computer using network management software.

Notes: 1. This switch supports four concurrent Telnet sessions.

2. The onboard program only provides access to basic configuration functions.

To access the full range of SNMP management functions, you must use
SNMP-based network management software.

Chapter 2: Console Interface

Log-in Screen

Once a direct connection to the serial port or a Telnet connection is established, the
log-in screen for the onboard configuration program appears as shown below.

Assigning SNMP Parameters

Use the SNMP Configuration screen to display and modify parameters for the
Simple Network Management Protocol (SNMP). The switch includes an SNMP
agent which monitors the status of its hardware, as well as the traffic passing
through its ports. A computer attached to the network, called a Network
Management Station (NMS), can be used to access this information. Access rights
to the switch are controlled by community strings. To communicate with the switch,
the NMS must first submit a valid community string for authentication. The options
for configuring community strings and related trap functions are described in the
following sections.

Using the Spanning Tree Algorithm

The Spanning Tree Algorithm can be used to detect and disable network loops, and
to provide backup links between switches, bridges or routers. This allows the switch
to interact with other bridging devices (that is, an STA-compliant switch, bridge or
router) in your network to ensure that only one route exists between any two stations
on the network. For a more detailed description of how to use this algorithm, refer to
“Spanning Tree Algorithm” on page 4-1.

Console Interface

Parameter Default Description

Max (Message) Age 20 The maximum time (in seconds) a device can wait

without receiving a configuration message before
attempting to reconfigure. All device ports (except for
designated ports) should receive configuration
messages at regular intervals. Any port that ages out
STA information (provided in the last configuration
message) becomes the designated port for the attached
LAN. If it is a root port, a new root port is selected from
among the device ports attached to the network.

The minimum value is
the higher of 6 or [2 x (Hello Time + 1)].

The maximum value is
the lower of 40 or [2 x (Forward Delay - 1)].

Forward Delay 15 The maximum time (in seconds) the root device will wait

before changing states (i.e., listening to learning to
forwarding). This de lay is required because every device
must receive infor mation about topology change s before
it starts to forward frames. In addition, each port needs
time to listen for conflicting information that would make
it return to a blocking state; otherwise, temporary data
loops might result.

The maximum value is 30.
The minimum value is

the higher of 4 or [(Max. Message Age / 2) + 1].

Status Displays the current state of this port within the spanning tree:

Disabled Port has been disabled by the user or has failed diagnostics.
No Link There is no valid link on the port.
Blocking Port receives STA configuration messages, but does not forward

packets.

Listening Port will leave blocking state due to topology change, starts

transmitting configuration messages, but does not yet forward packets.

Learning Has transmitted configuration messages for an interval set by the

Forward Delay parameter without receiving contradictory information.
Port address table is cleared, and the port begins learning addresses.

Forwarding The port forwards packets, and continues learning addresses.

The rules defining port status are:

• A port on a network segment with no other STA-compliant bridging device is
always forwarding.

• If two ports of a switch are connected to the same segment and there is no other
STA device attached to this segment, the port with the smaller ID forwards
packets and the other is blocked.

• All ports are blocked when the switch is booted, then some of the m change state
to listening, to learning, and then to forwarding.

Using a Mirror Port for Analysis

You can mirror traffic from any source port to a target port for real-time analysis. You
can then attach a network sniffer or RMON probe to the target port and study the
traffic crossing the source port in a completely unobtrusive manner. When mirroring
port traffic, note that the target port must be configured in the same VLAN as the
source port (see “Configuring Virtual LANs” on page 2-44).

You can use the Mirror Port Configuration screen to designate a single port pair for
mirroring as shown below:

Configuring Port Trunks

Port trunks can be used to increase the bandwidth of a network connection or to
ensure fault recovery. You can configure up to four trunk connections (combining
2~4 ports into a fat pipe) between any two OmniStack 8008 switches. However,
before making any physical connections between devices, use the Trunk
Configuration menu to specify the trunk on the devices at both ends. When using a
port trunk, note that:

• Ports can only be assigned to one trunk.

• The ports at both ends of a connection must be configured as trunk ports.

• The ports at both ends of a trunk must be configured in an identical manner,
including duplex mode, and VLAN assignments.

• None of the ports in a trunk can be configured as a mirror source port or mirror
target port.

• All the ports in a trunk have to be treated as a whole when moved from/to, added
or deleted from a VLAN.

• The Spanning Tree Algorithm will treat all the ports in a trunk as a whole.

• Enable the trunk prior to connecting any cable between the switches to avoid
creating a loop.

• Disconnect all trunk port cables or disable the trunk ports before removing a port
trunk to avoid creating a loop.

IGMP Multicast Filtering

Multicasting is used to support real-time applications such as video conferencing or
streaming audio. A multicast server does not have to establish a separate
connection with each client. It merely broadcasts its service to the network, and any
hosts which want to receive the multicast register with their local multicast switch/
router. Although this approach reduces the network overhead required by a
multicast server, the broadcast traffic must be carefully pruned at every multicast
switch/router it passes through to ensure that traffic is only passed on the hosts
which subscribed to this service.

This switch uses IGMP (Internet Group Management Protocol) 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/router to ensure that it will continue to receive the
multicast service. (For more information, see “IGMP Snooping” on page 4-5.)

Configuring Traffic Classes

IEEE 802.1p defines up to 8 separate traffic classes. This switch supports Quality of
Service (QoS) by using two priority queues, with Weighted Fair Queuing for each
port. You can use the 802.1P Configuration menu to configure the default priority for
each port, or to display the mapping for the traffic classes as described in the
following sections.

Port Priority Configuration

The default priority for all ingress ports is zero. Therefore, any inbound frames that
do not have priority tags will be placed in the low priority output queue. Default
priority is only used to determine the output queue for the current port; no priority tag
is actually added to the frame. You can use the 802.1P Port Priority Configuration
menu to adjust default priority for any port as shown below:

Console Interface

Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the switch to any of
up to 256 LAN groups. In conventional networks with routers, broadcast traffic is
split up into separate domains. Switches do not inherently support broadcast
domains. This can lead to broadcast storms in large networks that handle a lot of
IPX and NetBEUI traffic. By using IEEE 802.1Q compliant VLANs and GARP VLAN
Registration Protocol, you can organize any group of network nodes into separate
broadcast domains, confining broadcast traffic to the originating group. This also
provides a more secure and cleaner network environment. For more information on
how to use VLANs, see “Virtual LANs” on page 4-2. The VLAN configuration
screens are described in the following sections.

802.1Q VLAN Current Table Information

This screen shows the current port members of each VLAN and whether or not the
port supports VLAN tagging. Ports assigned to a large VLAN group that crosses
several switches should use VLAN tagging. However, if you just want to create a
small port-based VLAN for one or two switches, you can assign ports to the same
untagged VLAN (page 2-48). The current configuration is shown in the following
figure.

In addition to the menu-driven system configuration program, this switch also
provides an embedded HTTP Web agent. Using a Web browser you can configure
the switch and view statistics to monitor network activity. The Web agent can be
accessed by any computer on the network using a standard Web browser (Internet
Explorer 4.0 or above, or Netscape Navigator 4.0 or above).

Prior to accessing the switch from a Web browser, be sure you have first performed
the following tasks:

1. Configure it with a valid IP address, subnet mask, and default gateway using an
out-of-band serial connection or BOOTP protocol.

2. Set a user name and password using an out-of-band serial connection. Access
to the Web agent is controlled by the same user name and password as the
onboard configuration program.

SNMP Configuration

Use the SNMP Configuration screen to display and modify parameters for the
Simple Network Management Protocol (SNMP). The switch includes an SNMP
agent which monitors the status of its hardware, as well as the traffic passing
through its ports. A computer attached to the network, called a Network
Management Station (NMS), can be used to access this information. Access rights
to the switch are controlled by community strings. To communicate with the switch,
the NMS must first submit a valid community string for authentication. The options
for configuring community strings and related trap functions are described in the
following figures and table.

SNMP Community

The following figure and table describe how to configure the community strings
authorized for management access. Up to 5 community names may be entered.

STA (Spanning Tree Algorithm)

The Spanning Tree Algorithm can be used to detect and disable network loops, and
to provide backup links between switches, bridges or routers. This allows the switch
to interact with other bridging devices (that is, STA-compliant switch, bridge or
router) in your network to ensure that only one route exists between any two stations
on the network. For a more detailed description of how to use this algorithm, refer to
“Spanning Tree Algorithm” on page 4-1.

Priority

IEEE 802.1p defines up to 8 separate traffic classes. This switch supports Quality of
Service (QoS) by using two priority queues, with weighted fair queuing for each port.
You can use the Priority menu to configure the default priority for each port, or to
display the mapping for the traffic classes as described in the following sections.

Port Priority Configuration

The default priority for all ingress ports is zero. Therefore, any inbound frames that
do not have priority tags will be placed in the low priority output queue. Default
priority is only used to determine the output queue for the current port; no priority tag
is actually added to the frame. You can use the Port Priority Configuration screen to
adjust default priority for any port as shown below:

Parameter Description

Configuring Virtual LANs

Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the switch to any of
up to 256 VLAN groups. In conventional networks with routers, broadcast traffic is
split up into separate domains. Switches do not inherently support broadcast
domains. This can lead to broadcast storms in large networks that handle a lot of
IPX and NetBEUI traffic. By using IEEE 802.1Q compliant VLANs and GARP VLAN
Registration Protocol, you can organize any group of network nodes into separate
broadcast domains, confining broadcast traffic to the originating group. This also
provides a more secure and cleaner network environment. For more information on
how to use VLANs, see “Virtual LANs” on page 4-2. The VLAN configuration
screens are described in the following sections.

This switch accepts “All” frame types, including VLAN tagged or VLAN
untagged frames. Note that all VLAN untagged frames received on this port
are assigned to the PVID for this port.

If set to “True,” incoming frames for VLANs which do not include this port in
their member set will be discarded at the inbound port.

Enables or disables GVRP for this port. When disabled, any GVRP packets
received on this port will be discarded and no GVRP registrations will be
propagated from other ports.

Note that, before this port setting takes effect, GVRP must be enabled for the
switch (see Configuring Bridge MIB Extensions on page 3-21).

IGMP Multicast Filtering

IGMP Multicast Filtering

Multicasting is used to support real-time applications such as video conferencing or
streaming audio. A multicast server does not have to establish a separate
connection with each client. It merely broadcasts its service to the network, and any
hosts that want to receive the multicast register with their local multicast switch/
router. Although this approach reduces the network overhead required by a
multicast server, the broadcast traffic must be carefully pruned at every multicast
switch/router it passes through to ensure that traffic is only passed on to the hosts
that subscribed to this service.

This switch uses IGMP (Internet Group Management Protocol) 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/router to ensure that it will continue to receive the
multicast service. (For more information, see “IP Multicast Filtering” in the Users
Guide.)

Configuring IGMP

This protocol allows a host to inform its local switch/router that it wants to receive
transmissions addressed to a specific multicast address group. Use the IGMP
Configuration screen to set key parameters for multicast filtering as shown below.

Parameter Description

IGMP Status If enabled, the switch will monitor network traffic to determine which hosts

Port Information

The Port Information screen displays the port status, link state, the communication
speed and duplex mode, as well as the flow control in use. To change any of the port
settings, use the Port Configuration menu. The parameters shown in the following
figure and table are for the RJ-45 ports.

Parameter Description

Admin Status Shows if the port is enabled or not.

Link Status Indicates if the port has a valid connection to an external device.

Speed Status Shows the port speed (1000M).

Duplex Status Displays the current duplex mode.

Flow Control Status Shows the flow control type in use. Flow control can eliminate frame loss by

“blocking” traffic from end stations connected directly to the switch. Back
pressure is used for half duplex and IEEE 802.3x for full duplex.

Note: The port information displayed is not valid if the link status is down.
