Setting The Mtu For A Layer 3 Aggregate Interface; Setting The Minimum And Maximum Numbers Of Selected Ports For An Aggregation Group - H3C S7500E-X Configuration Manual

Setting the MTU for a Layer 3 aggregate interface

The MTU of an interface affects IP packets fragmentation and reassembly on the interface.
To set the MTU for a Layer 3 aggregate interface:
Step
Enter system view.

aggregate interface.
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 states of aggregation member ports and the
state of the aggregate interface.
•
When the number of member ports eligible to be Selected ports is smaller than the minimum
threshold, the following events occur:
The eligible member ports are placed in the Unselected state.
The link layer state of the aggregate interface becomes down.
•
When the number of member ports eligible to be Selected ports reaches or exceeds the
minimum threshold, the following events occur:
The eligible member ports are placed in the Selected state.
The link layer state of the aggregate interface becomes up.
The maximum number of Selected ports allowed in an aggregation group is limited by either the
configured maximum number or hardware limitation, 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.
Then, only one Selected port is allowed in the aggregation group at any point in time, and the
Unselected port acts as a backup port.
To set the minimum and maximum numbers of Selected ports for an aggregation group:
Step
Enter system view.
