LAG Hash Options
Command Syntax and Usage
[no] portchannel thash localpreference
Enables or disables local preference for known unicast traffic. When enabled,
unicast packets that need to exit the stack through a certain portchannel are
hashed using only the portchannel member ports of the ingress switch.
Otherwise, when disabled or if the ingress switch doesn't have any member
ports, the packet is hashed using all portchannel member ports across the
whole stack.
The default setting is disabled.
This option reduces the traffic bandwidth over the stacking links.
Note: In stacking, this command is available only on the Master switch.
