1.3.6 (Optional) Limiting the Number of Active Interfaces

Context
Perform the following steps on the AR3200 to limit the number of active interfaces.
Procedure
l
Issue 02 (2012-03-30)
NOTE
All Layer 2 Eth-Trunks in the system must use the same load balancing mode. If the load
balancing mode of one Eth-Trunk is changed, all the other Eth-Trunks use the new load
balancing mode.
Configuring a Layer 3 Eth-Trunk interface
1. Run:
system-view
The system view is displayed.
2. Run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
3. Run:
load-balance { dst-ip | dst-mac | src-ip | src-mac | src-dst-ip | src-dst-
mac }
The load balancing mode is configured for the Eth-Trunk.
By default, the load balancing mode of a Layer 3 Eth-Trunk is src-dst-ip.
Member interfaces of an Eth-Trunk perform per-flow load balancing. The local end
and the remote end can use different load balancing modes, without affecting each
other.
Setting the maximum number of interfaces that determine bandwidth for an Eth-Trunk
1. Run:
system-view
The system view is displayed.
2. Run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
3. Run:
max bandwidth-affected-linknumber link-number
The maximum number of interfaces that determine bandwidth for the Eth-Trunk is
set.
By default, the maximum number of interfaces that determine bandwidth for an Eth-
Trunk is 8.
