4 Web-based Switch Configuration
To Port: The ending of a consecutive group of ports may be configured starting with the selected port.
Port Priority (0-65535): Displays the LACP priority value for the port. Default is 128.
Activity: There are two different roles of LACP ports:
Active - Active LACP ports are capable of processing and sending LACP control frames. This allows
LACP compliant devices to negotiate the aggregated link so the group may be changed dynamically
as needs require. In order to utilize the ability to change an aggregated port group, that is, to add or
subtract ports from the group, at least one of the participating devices must designate LACP ports as
active. Both devices must support LACP.
Passive - LACP ports that are designated as passive cannot initially send LACP control frames. In
order to allow the linked port group to negotiate adjustments and make changes dynamically, one
end of the connection must have "active" LACP ports.
Timeout: Specify the administrative LACP timeout. The possible field values are:
Short (3 Sec) - Defines the LACP timeout as 3 seconds.
Long (90 Sec) - Defines the LACP timeout as 90 seconds. This is the default value.

Configuration > IGMP Snooping > IGMP Snooping
With Internet Group Management Protocol (IGMP) snooping, the DGS-2000 Series Ethernet Switch can
make intelligent multicast forwarding decisions by examining the contents of each frame's Layer 2 MAC
header.
IGMP snooping can help reduce cluttered traffic on the LAN. With IGMP snooping enabled globally, the
DGS-2000 Series Ethernet Switch will forward multicast traffic only to connections that have group members
attached.
The settings of IGMP snooping is set by each VLAN individually.
By default, IGMP is disabled. If enabled, the IGMP Global Settings will need to be entered:

Description
Used to control IGMP snooping global state; the radios buttons
enable/disable to change the state.
Enable: Specifies that the multicast group will be based on the host
mode.
Disable: Specifies that the multicast forwarding lookup will be based
on the port mode.
This is the interval after which a learned host port entry will be
purged. For each host port learned, a 'Port Purge Timer' runs for
'Host Port Purge Interval'. This timer will be restarted whenever a
report message from host is received over that port. If no report
messages are received for 'Host Port Purge Interval' time, the
