Enabling Trill Distribution Tree Multithread Calculation; Enabling Load Balancing Over Trill Distribution Trees - H3C S10500 Series Configuration Manual

Step
Configure the number of
4.
TRILL distribution trees that
the RB wants all RBs to
compute.

Enabling TRILL distribution tree multithread calculation

This feature enables a multicore CPU device to improve TRILL distribution tree calculation efficiency
by using each thread to calculate a distribution tree.
To enable TRILL distribution tree multithread calculation:
Step
Enter system view.
1.
Enter TRILL view.
2.
Enable TRILL distribution
3.
tree multithread calculation.

Enabling load balancing over TRILL distribution trees

By default, ingress traffic is not load balanced over TRILL distribution trees after a forwarding VLAN
is deleted on the RB. To load balance ingress traffic of the remaining forwarding VLANs over the
existing distribution trees, you can enable load balancing over TRILL distribution trees.
Ingress traffic is load balanced in any of the following conditions, regardless of whether load
balancing is enabled or not:
•
A forwarding VLAN is added.
•
A distribution tree is added or deleted.
When a distribution tree is added, the RB switches ingress traffic to the new tree to implement load
balancing. However, the RB cannot use the new distribution tree to forward traffic before other RBs
are ready to use the new tree. In this case, you can set a delay timer for the RB to switch ingress
traffic to the new distribution tree.
If traffic is not evenly distributed over distribution trees when load balancing is disabled, you can also
perform one-time load balancing over TRILL distribution trees.
To enable load balancing over TRILL distribution trees:
Step
Enter system view.
1.
Enter TRILL view.
2.
Enable load balancing over
3.
TRILL distribution trees.
Set the delay timer for the
4.
RB to switch ingress traffic
to a new TRILL distribution
tree.
