following options:

2 Minutes, 5 Minutes, 10 Minutes, 15 Minutes

or

Never.

Serial Port Baud

Rate

Fixed at 115200.

MAC Address Aging

Time

This field specifies the length of time a learned MAC Address will remain in

the forwarding table without being accessed (that is, how long a learned

MAC Address is allowed to remain idle).

The default age-out time for the

Switch is 300 seconds. To change this, type in a different value

representing the MAC address age-out time in seconds. The Aging Time

can be set to any value between

10

and

1,000,000

seconds.

IGMP Snooping

To enable system-wide IGMP Snooping capability select

Enabled

. IGMP

snooping is

Disabled

by default. Enabling IGMP snooping allows you to

specify use of a multicast router only (see below). To configure IGMP

Snooping for individual VLANs, use the

IGMP Snooping

page under the

IGMP

folder.

Multicast Router

Only

If this option is enabled and IGMP Snooping is also enabled, the switch

forwards all multicast traffic to a multicast-enabled router only.

Otherwise,

the switch will forward all multicast traffic to any IP router.

GVRP

Use this pull-down menu to

Enable

or

Disable

GVRP on the switch.

Telnet Status

Telnet configuration is

Enabled

by default. If you do not want to allow

configuration of the system through Telnet choose

Disabled

.

Web Status

Web-based management is

Enabled

by default. If you choose to disable

this by selecting

Disabled

, you will lose the ability to configure the system

through the web interface as soon as these settings are applied.

RMON Status

Remote monitoring (RMON) of the switch is

Enabled

or

Disabled

here.

Link Aggregation

Algorithm

The algorithm that the switch uses to balance the load across the ports that

make up the port trunk group is defined by this definition. Choose

Source

Address, Destination Address

or

Both.

(See Link Aggregation).

Switch 802.1x

Enables or disables 802.1x VLANs; default is Disabled.

Auth Protocol

You can select between

Radius Eap

or Local.

HOL State

Enables or disables HOL (Head of Line) prevention; default is Enabled.

Jumbo Frame

Enables or disables Jumbo Frame acceptance; default is Disabled.

Syslog State

Enables or disables Syslog State; default is Disabled.

Configuring Ports

This section contains information for configuring various attributes and properties for

individual physical ports, including port speed and flow control. Clicking on

Port

Configurations

in the

Configuration

menu will display the following window for the user.

The

Unit

pull-down menu refers to the module installed in the DES-6500 chassis that you

want to configure ports for.

The modules are numbered from 1 at the top (just below the

DES-6502 CPU module) to 8 at the bottom (the slot farthest from the CPU module).

Use the remaining pull-down menus to configure the parameters described below:

Toggle the

field to either select the speed and

duplex/half-duplex state of the port. Auto – auto-negotiation between

10 and 1000 Mbps devices, full- or half-duplex. The Auto setting

allows the port to automatically determine the fastest settings the

device the port is connected to can handle, and then to use those

settings. The other options are

auto, 10M/Half, 10M/Full, 100M/Half,

100M/Full

,

1000M/Full Master,

and

1000M/Full Slave.

There is no

automatic adjustment of port settings with any option other than

Auto

.

Flow Control

Displays the flow control scheme used for the various port

configurations. Ports configured for full-duplex use 802.3x flow

control, half-duplex ports use backpressure flow control, and Auto

ports use an automatic selection of the two.

The default is

Disabled

.

Learning

Enable or disable MAC address learning for the selected ports. When

Enabled

, destination and source MAC addresses are automatically

listed in the forwarding table. When learning is

Disabled

, MAC

addresses must be manually entered into the forwarding table. This is

sometimes done for reasons of security or efficiency. See the section

on

Forwarding/Filtering

for information on entering MAC addresses

into the forwarding table.

Configuring Port Mirroring

The Switch allows you to copy frames transmitted and received on a port and redirect the

copies to another port. You can attach a monitoring device to the mirrored port, such as a

network sniffer or an RMON probe, to view details about the packets passing through the first

port. This is useful for network monitoring and troubleshooting purposes. To view the

Setup

Port Mirroring

window, click

Port Mirroring

in the

Configuration

folder.

Figure 4- 2. Setup port Mirroring window

To configure a mirror port:

1. Select the

Source Port

from where you want to copy frames and the

Target Port

,

which receives the copies from the source port.

2. Select the Source Direction,

Ingress, Egress

, or

Both

and

change the

Status

drop-

down

menu to

Enabled.

None

is equivalent to

Disabled

in the

pull-down

menu.

3. Click

to let the changes take effect.

NOTE:

You cannot mirror a fast port onto a slower port. For

example, if you try to mirror the traffic from a 100 Mbps port onto a

10 Mbps port, this can cause throughput problems. The port you are

copying frames from should always support an equal or lower speed

than the port to which you are sending the copies. Also, the target

port for the mirroring cannot be a member of a trunk group. Please

note a target port and a source port cannot be the same port.

Configuring Link Aggregation

Understanding Port Trunk Groups

Port trunk groups are used to combine a number of ports together to make a single high-

bandwidth data pipeline.

The Switch treats all ports in a trunk group as a single port.

Data transmitted to a specific host

(destination address) will always be transmitted over the same port in a trunk group. This

allows packets in a data stream to arrive in the same order they were sent.

Note

: If ports become disconnected within a trunk group,

intended packets will be load shared to the other up-linked

ports of the link aggregation group.

Link aggregation allows several ports to be grouped together and to act as a single link. This

gives a bandwidth that is a multiple of a single link’s bandwidth.

Link aggregation is most commonly used to link a bandwidth intensive network device or

devices, such as a server, to the backbone of a network.

All ports in the group must be a member of the same VLAN and their STP status

configuration, static multicast entries, traffic control, traffic segmentation and 802.1p default

priority, must be identical. Also, port locking, port mirroring and 802.1X must not be enabled

on the trunk group. Further, the aggregated links must all be of the same speed and should be

configured as full-duplex.

The Master Port of the group, becomes the configuration for all of the ports in the aggregation

group and all configuration options, including the VLAN configuration, that can be applied to

the Master Port are applied to the entire link aggregation group.

Load balancing is automatically applied to the ports in the aggregated group, and a link failure

within the group causes the network traffic to be directed to the remaining links in the group.

The Spanning Tree Protocol will treat a link aggregation group as a single link, on the switch

level. On the port level, the STP will use the port parameters of the Master Port in the

calculation of port cost and in determining the state of the link aggregation group. If two

redundant link aggregation groups are configured on the switch, STP will block one entire

group, in the same way STP will block a single port that has a redundant link.
