•Administrative Duplex Mode—If Auto Negotiation is disabled, select Half 
for half-duplex or Full for full-duplex operation.
•Admin Advertisement—If Autonegotiation is enabled, select the highest 
port speed and duplex setting that you want the port to negotiate. If you 
select Max Capacity, the port autonegotiates up to the highest port speed 
and duplex setting supported by hardware.

Link Aggregation
Link Aggregation allows one or more full-duplex Ethernet links to be aggregated 
together to form a Link Aggregation Group (LAG). The switch treats the LAG as if it 
is a single physical port, with improved fault tolerance and load- sharing capability.
A LAG interface can be either static or dynamic:
•Static LAG—Ports are assigned to a LAG directly by the administrator. The 
ports remain...

LAGs can be assigned membership in VLANs; however, individual ports lose their 
individual VLAN memberships when they become LAG members. When a port is 
removed from a LAG, it rejoins the VLANs that it previously belong to as specified 
in the startup configuration.
To configure a LAG:
STEP 1Select a LAG to configure, and then click Edit.
STEP  2Specify the following for the selected LAG:
•LAG Name—Enter up to...

•Load Balance Algorithm—Select one of the options to enable the switch to 
load-balance outgoing packets among member ports of a LAG. The switch 
selects one of the links in the channel for transmitting specific packets. The 
switch prioritizes each criteria for load balancing in the order listed in the 
option. The options are:
-Src/Dest MAC, VLAN, EType, incoming port—Source and destination 
MAC addresses, the...

•Admin Key—A number that determines the dynamic LAG(s) that the 
interface can join. All interfaces in a dynamic LAG must share the same 
admin key.
•Port Priority—A nonconfigurable priority assigned to the port.
•LACP Aggregation—The port mode with respect to link aggregation. This 
field is not configurable. Possible values are:
-Aggregate—The port is participating in link aggregation.
-Individual—The port is...

-Long—Long LACP timeout is 3 times the long periodic timer to transmit 
LACP packets. The default Long LACP timeout is 90 seconds.

Configuring PoE
On the SF200E-24P switch, ports 1–6 and 13–18 can operate as Power-over-
Ethernet (PoE) power-sourcing equipment (PSE). PSE ports can provide power to 
connected PoE Powered...

•Power Management Mode—Select how the switch prioritizes the power 
that it provides to multiple ports:
-Static with Port Priority—Static with priority power management. This 
algorithm pre-allocates power based on the configured power limit and 
the priority of the port. 
-Dynamic with Port Priority—Dynamic with priority power 
management. This algorithm supplies power to devices as long as the 
consumption is...

Configuring PoE Port Settings
You can use the Por t Settings page to view and configure settings for ports acting 
as PSEs.
To configure PoE settings for a port:
STEP 1Click Port Management > PoE > Port Settings in the navigation window.
The PoE Setting Table displays which ports are enabled for PoE operation, their 
priority, power allocation in milliwatts, and other settings for each port.
STEP  2Select the port...

-Dot3AF and LLDP-MED—The maximum power that can be delivered 
by the port is limited by the value in LLDP-MED TLVs received from a 
port device. The value specified by the device should be in the range of 
3-16.2 watts. If it is not in this range, then the maximum power is limited 
by the IEEE 802.3AF class.

itself to the PSE. A signature is generated during powered device detection, 
classification, or maintenance.
