The factory default is Enable, which causes the trap to be sent.
10. Use STP Mode to enable or disable the Spanning
Tree Protocol administrative mode
associated with the LAG.
The possible values are as follows:
• Disable. Spanning tree is disabled for this LAG.
• Enable. Spanning tree is enabled for this LAG. Enable is the default.
11. Use Static Mode to select enable or disable.
When the LAG is enabled, it does not transmit or process received LACPDUs that is, the
member ports do not transmit LACPDUs and all the LACPDUs it can receive are
dropped.
The factory default is Disable.
12. 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,EType,incoming port. Source MAC, VLAN, EtherT
ype, and incoming
port associated with the packet.
• Dest MAC,VLAN,EType,incoming port. Destination MAC, VLAN, EtherT
ype, and
incoming port associated with the packet.
• Src/Dest MAC,VLAN,EType,incoming port. Source/Destination MAC, VLAN,
EtherT
ype, and incoming port associated with the packet. This option 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.
13. Use the Port Selection T
able to select the ports as members of the LAG.
14. Click the Apply button.
