Configures the hash control method on the switch. Depending upon this configuration, hashing algorithm 
used by various applications for packet forwarding will be affected.

Sets hashing to brief mode.

Sets hashing to extended mode.

Sets hashing to use UDP/TCP ports.

• It is recommended to disable TCP-UDP port hashing when Server Load Balancing is configured due to 

SLB’s use of dynamic port assignments.

• The hash control setting also impacts the fabric load balancing for Chassis based products. It is recom-

mended not to set brief hashing mode on Chassis based products.

• Changing the hash control mode affects the hashing algorithm for Link Aggregation, Server Load 

Balancing and EMCP. 

• The hashing mode must be set to extended to enable UDP/TCP port hashing.
