Discarded Frames

If an LLDP frame is received on a port, and the switch's internal table has run full, the LLDP

frame is counted and discarded. This situation is known as "Too Many Neighbors" in the

LLDP standard. LLDP frames require a new entry in the table when the Chassis ID or

Remote Port ID is not already contained within the table. Entries are removed from the

table when a given port links down, an LLDP shutdown frame is received, or when the entry

ages out.

TLVs Discarded

Each LLDP frame can contain multiple pieces of information, known as TLVs (TLV is short

for "Type Length Value"). If a TLV is malformed, it is counted and discarded.

TLVs Unrecognized

The number of well-formed TLVs, but with an unknown type value.

Org. TLVs Discarded

The number of organizationally TLVs received.

AgeOuts

Each LLDP frame contains information about how long time the LLDP information is valid

(age-out time). If no new LLDP frame is received within the age out time, the LLDP

information is removed, and the Age-Out counter is incremented.

4.15 Green Networking

In line with the energy-saving trend worldwide, PLANET delivers the new generation green Switch- GSW-1602SF /

GSW-2404SF Series Web Smart Gigabit Ethernet Switch. With both benefit of energy saving and gigabit performance, the

new engine that provides power saving for less energy consumption but not reduce the Gigabit performance.

The GSW-1602SF / GSW-2404SF incorporate two advanced Green Networking technologies:

„

Hibernation Link Down power saving

„

Intelligent scales power based on cable length

The Hibernation Link Down power savings goes beyond IEEE specifications to automatically lower power for a given port

when it is not linked. With the Hibernation Link Down power savings technology, the GSW-1602SF / GSW-2404SF will

automatically adjusts power usage of the ports that are shutdown or not connected to network device. The other technology

adopted, intelligent scales power, is an intelligent algorithm that actively determines the appropriate power level based on

cable length. The Green Networking screen in

Figure 4-89

appears.
