8. Port Security:

A port in security mode will be “locked” without permission of address learning. Only

the incoming packets with SMAC already existing in the address table can be forwarded normally.

User can disable the port from learning any new MAC addresses, then use the static MAC addresses

screen to define a list of MAC addresses that can use the secure port. Enter the settings, then click

2.5.5 Trunking

The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging

information between Partner Systems on a link to allow their Link Aggregation Control instances to reach

agreement on the identity of the Link Aggregation Group to which the link belongs, move the link to that

Link Aggregation Group, and enable its transmission and reception functions in an orderly manner. In

conclusion, Link aggregation lets you group up to eight consecutive ports into a single dedicated

connection. This feature can expand bandwidth to a device on the network.

LACP operation requires

full-duplex mode,

more detail information refers to IEEE 802.3ad

2.5.5.1 Aggregator setting

1. System Priority:

A value used to identify the active LACP. The switch with the lowest value has the

highest priority and is selected as the active LACP. Valid value is 1~65535.

2. Group ID:

There are seven trunk groups to provide configure. Choose the "group id" and click

"Get".

3. LACP:

If enable, the group is LACP static trunking group. If disable, the group is local static

trunking group. All ports support LACP dynamic trunking group. If connecting to the device that also

- 27 -

supports LACP, the LACP dynamic trunking group will be created automatically.

4. Work ports:

Allow max four ports can be aggregated at the same time. If LACP static trunking

group, the exceed ports is standby and able to aggregate if work ports fail. If local static trunking

group, the number must be as same as the group member ports.

5.

Select the ports to join the trunking group. Allow max four ports can be aggregated at the same time.

6.

If LACP enable, you can configure LACP Active/Passive status in each port on State Activity page.

7.

Click Apply.

2.5.5.2 Aggregator Information

When you are setting LACP aggregator, you can see relation information in here.

1.

This page is no group active. LACP don’t working.

2.

This page is Static Trunking groups.

3.

This page is Actor and Partner trunking one group.

2.5.5.3 State Activity

Active

(select)

:

The port automatically sends LACP protocol packets.

N/A

(no select)

:

The port does not automatically sends LACP protocol packets, and responds only if it

receives LACP protocol packets from the opposite device.

1.

A link that has either two active LACP ports or one active port can perform dynamic LACP trunking.

A link has two N/A LACP ports will not perform dynamic LACP trunking because both ports are

waiting for and LACP protocol packet from the opposite device.

2

. If you are active LACP’s actor, when you are select trunking port, the active status will be created

automatically.

2.5.6 IGMP and MAC Filter

2.5.6.1. IGMP Snooping

The

24+2G

switch supports multicast IP. One can enable IGMP protocol on this web page, and then

display the IGMP snooping information on this page. There are all multicast groups, VIDs and member

ports in the list. IP multicast addresses range from 224.0.0.0 through 239.255.255.255.

The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP)

suite.

IGMP can manage the multicast traffic if the members (switches, router or other network devices) of

group support IGMP. With IGMP enable, the member ports will detect IGMP queries, report packets and

manage the IP multicast traffic through the switch.

IGMP have three fundamental types of message as follows:

Message

Description

Query

A message sent from the queries (IGMP router or switch) asking for a

response from each host belonging multicast group.

Report

A message sent by a host to the queries to indicate that the host wants to be or

is a member of a given group indicated in the report message.

Leave Group

A message sent by a host to the queries to indicate that the host has quit being

a member of a specific multicast group.
