Port Settings
Allows the selection of ports that will be members of the static multicast group and ports
either that are forbidden from joining dynamically, or that can join the multicast group
dynamically, using GMRP. The options are:
None
- No restrictions on the port dynamically joining the multicast group. When None is
chosen, the port will not be a member of the Static Multicast Group.
Egress
- The port is a static member of the multicast group.

to implement the changes made. To delete an entry in the Static Multicast Forwarding Table, click the
corresponding

button. All the entries will be shown on the lower half of the
Multicast F orwarding T able
window.
LLDP
The Link Layer Discovery Protocol (LLDP) allows stations attached to an IEEE 802 LAN to advertise, to other stations
attached to the same IEEE 802 LAN. The major capabilities provided by this system is that it incorporates the station,
the management address or addresses of the entity or entities that provide management of those capabilities, and the
identification of the station’s point of attachment to the IEEE 802 LAN required by those management entity or entities.
The information distributed via this protocol is stored by its recipients in a standard Management Information Base
(MIB), making it possible for the information to be accessed by a Network Management System (NMS) through a
management protocol such as the Simple Network Management Protocol (SNMP).

The following parameters can be set:
Parameter Description
LLDP State
Used to Enable or Disable LLDP on the Switch.
LLDP Forward
Message
When LLDP is disabled this function controls the LLDP packet forwarding message based on
individual ports. If LLDP is enabled on a port it will flood the LLDP packet to all ports that have
the same port VLAN and will advertise to other stations attached to the same IEEE 802 LAN.
Message TX
Interval (5-32768)
This interval controls how often active ports retransmit advertisements to their neighbors. To
change the packet transmission interval, enter a value in seconds (
5
to
32768
).
Message TX Hold
Multiplier (2-10)
This function calculates the Time-to-Live for creating and transmitting the LLDP advertisements
to LLDP neighbors by changing the multiplier used by an LLDP Switch. When the Time-to-Live
for an advertisement expires the advertised data is then deleted from the neighbor Switch’s MIB.
LLDP Reinit
The LLDP reinitialization delay interval is the minimum time that an LLDP port will wait before
