198
M4100 Series Managed Switch
The default admin user name is admin and the default admin password is blank, that is,
do not enter a password.
6. Click the Login button.
The web management interface menu displays.
7. Select Switching
 LAG  LAG Configuration.
8. Use LAG Name to enter the name you want assigned to the LAG.
You can enter any string of up to 15 alphanumeric characters. A valid name must be
specified for you to create the LAG.
9. Use the list to enable or disable Admin Mode.
When the LAG is disabled, no traffic flows and LACPDUs is dropped, but the links that
form the LAG are not released.
The default is enable.
10. 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 switch selects the link by creating a binary
pattern from selected fields in a packet, and associating that pattern with a particular link:
• Src MAC, VLAN, ET
ype,i ncoming 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 IP and Src TCP/UDP Port — Source IP and Source TCP/UDP fields of the packet.
• Dest IP and Dest TCP/UDP Port — Destination IP and Destination TCP/UDP Port
fields of the packet.
• Src/Dest IP and TCP/UDP Port — 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.
