To configure link aggregation settings, do as follows:
1)
Select an aggregation algorithm from the Aggregation Algorithm drop-down list. Available options include
port number Source MAC, Dest MAC and Source & Dest MAC. The default is Source & Dest MAC.
2)
Select port numbers from Group Member.
3)
Select Enable from Link Aggregation drop-down list box.
4)
Click Save to complete your configurations.
4. Aggregation Algorithm
Member ports in a link aggregation group share traffic load according to specified aggregation algorithms.
Aggregation Algorithm
Description
Port ID
Member ports in a link aggregation group share traffic load according to the
receiving port numbers.
SMAC
Member ports in a link aggregation group share traffic load according to source
MAC addresses.
DMAC
Member ports in a link aggregation group share traffic load according to
destination MAC addresses.
SMAC & DMAC
Member ports in a link aggregation group share traffic load according to source
and destination MAC addresses.
IMPORTANT:
Below ports cannot be aggregated:
Mirroring destination port
Ports on which MAC address binding is enabled
3.4 PoE
PoE Overview
Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electrical power
along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power
to devices such as network hubs, IP camera, wireless AP and closed-circuit TV cameras, etc. The IEEE standard for
PoE requires category 5 cable or higher for high power levels, but can operate with category 3 cable if less power is
required.
The original IEEE 802.3af PoE standard provides up to 15.4 W of DC power to each device. Only 12.95W is
assured to be available at the powered device as some power is dissipated in the cable.
The updated IEEE 802.3at PoE standard also known as PoE+ or PoE plus, provides up to 25.5 W of power.
Power sourcing equipment
Power sourcing equipment (PSE) is a device such as a switch that provides ("sources") power on the Ethernet cable.
The maximum allowed continuous output power per cable in IEEE 802.3af is 15.40 W. A later specification, IEEE
