Configuration Guide - SPU
the subsequent requests of the user are sent to the same server. The SPU thus does not make
load balancing decisions.
The SPU supports static and dynamic stickiness:

The SPU supports session stickiness at the network layer and the application layer.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
load-balance stickygroup stickygroup-name mask net-mask { source-ip | destination-
ip |
A sticky group is created and the sticky group view is displayed.
Up to 1024 sticky groups can be created.
By default, no sticky group is created.
Step 3 (Optional) Run:
description text
The description of the sticky group is configured.
By default, no description is configured for a sticky group.
Step 4 Run:
group master-group-name [
A server group is bound to the sticky group.
The name of a backup load balancing group must be different from the name of the master load
balancing group.
If the Layer 3 classifier bound to the sticky group is bound to a load balance policy, you cannot
modify the server group bound to the sticky group.
By default, no server group is bound to a sticky group.
Step 5 (Optional) Run:
time-out time
The aging time of dynamic sticky entries is set.
The dynamic sticky entries generated on a sticky group age after the aging time expires and
never take effect.
By default, the aging time of dynamic sticky entries is 1440 minutes.
Issue 01 (2011-07-15)
When packets of a session match static sticky entries, the stickiness corresponding to the
session is called static stickiness. Static stickiness takes effect as long as static sticky entries
exist.
When packets of a session match dynamic sticky entries, the stickiness corresponding to
the session is called dynamic stickiness. Dynamic stickiness takes effect only in the aging
time. After dynamic sticky entries age, stickiness becomes invalid.
