configure sharing address-based
This command specifies the part of the packet header that the switch examines to select the egress port
for address-based load-sharing trunks. The address-based load-sharing setting is global and applies to
all load-sharing trunks, or LAGs, that are address-based. You change this setting by issuing the
command again with a different option.
To verify your configuration, use the command.
show ports sharing
This is a global setting and applies to all load-sharing trunks that are address-based.
Because the algorithms L2_L3__CHK_SUM and L2_L3_L4_CHK_SUM use the IP check sum as part of
the decision for the egress port selection, these algorithms do not guarantee the packet sequencing
between the clients. Also, these variables apply only to IPv4 addresses.
If you do not explicitly select an algorithm, the port-based scheme is used. However, the address-based
algorithm has a more even distribution and is the recommended choice.
Beginning with ExtremeWare XOS software version 11.3, you can configure dynamic link aggregation,
using LACP.
Example
The following example configures the switch to examine the MAC source and destination address:
configure sharing address-based l2
