Setting The Minimum And Maximum Numbers Of Selected Ports For An Aggregation Group - HP FlexFabric 12900 Series Configuration Manual

The system ignores the permit state and tagging mode of an ignored VLAN when choosing Selected
ports.
To configure ignored VLANs on a Layer 2 aggregate interface:
Step
1. Enter system view.
2. Enter Layer 2 aggregate
interface view.
3. Configure ignored VLANs.
Setting the minimum and maximum numbers of Selected ports
for an aggregation group
IMPORTANT:
The minimum and maximum number of Selected ports must be the same for the local and peer
aggregation groups.
The bandwidth of an aggregate link increases as the number of Selected member ports increases. To
avoid congestion, you can set the minimum number of Selected ports required for bringing up an
aggregate interface.
This minimum threshold setting affects the aggregation state of both aggregation member ports and the
aggregate interface.
When the number of member ports eligible to be Selected ports is smaller than the minimum
•
threshold:
All member ports are placed in the Unselected state.
The link of the aggregate interface goes down.
When the minimum threshold is reached, the eligible member ports are placed in the Selected state,
•
and the link of the aggregate interface goes up.
The maximum number of Selected ports allowed in an aggregation group is limited by either the
configured maximum number or hardware capability, whichever value is smaller.
You can configure backup between two ports by performing the following tasks:
Assign two ports to an aggregation group.
•
Configure 1 as the maximum number of Selected ports allowed in the aggregation group.
•
In this way, only one Selected port is allowed in the aggregation group at any point in time, while the
Unselected port acts as a backup port.
To set the minimum and maximum numbers of Selected ports for an aggregation group:
Step
1. Enter system view.
