LAG Configuration
Use the LAG (Port Channel) Configuration page to group one or more full-duplex Ethernet
links to be aggregated together to form a link aggregation group, which is also known as a
port-channel. The switch treats the LAG as if it were a single link.
To access the LAG Configuration page, click Switching
 LAG  LAG Configuration.
To configure LAG settings:
1. Use LAG Name to enter the name you want assigned to the LAG.
You may enter any
string of up to 15 alphanumeric characters. A valid name has to be specified in order to
create the LAG.
2. Use Admin Mode to select enable or disable from the menu. When the LAG is disabled no
traf
fic will flow and LACPDUs will be dropped, but the links that form the LAG will not be
released. The factory default is enable.
3. Use Hash Mode to select the load-balancing mode used on a port-channel (LAG).
Traffic is
balanced on a port-channel (LAG) by selecting one of the links in the channel over which to
transmit specific packets. The link is selected by creating a binary pattern from selected
fields in a packet, and associating that pattern with a particular link:
• Src MAC,VLAN,ET
ype,incoming port - Source MAC, VLAN, EtherType, and
incoming port associated with the packet.
• Dest MAC,VLAN,ET
ype,incoming port -Destination MAC, VLAN, EtherType, and
incoming port associated with the packet.
• Src/Dest MAC,VLAN,ET
ype,incoming port - Source/Destination MAC, VLAN,
EtherType, and incoming port associated with the packet. Src/Dest
MAC,VLAN,EType,incoming port is the default.
• Src IP and Src TCP/UDP Port fields - Source IP and Source
TCP/UDP fields of the
packet.
• Dest IP and Dest TCP/UDP Port fields - Destination IP and Destination
TCP/UDP Port
fields of the packet.
• Src/Dest IP and TCP/UDP Port Fields - Source/Destination IP and source/destination
TCP/UDP Port fields of the packet.
• Enhanced hashing mode - Features MODULO-N operation based on the number of
ports in the LAG, non-Unicast traf
fic and unicast traffic hashing using a common hash
algorithm, excellent load balancing performance, and packet attributes selection
based on the packet type:
• For L2 packets, source and destination MAC address are used for hash
computation.
• For L3 packets, source IP
, destination IP address, TCP/UDP ports are used.
