Setting The Mtu For A Layer 3 Aggregate Interface; Setting The Minimum And Maximum Numbers Of Selected Ports For An Aggregation Group - HP 6125XLG Configuration Manual

Setting the MTU for a Layer 3 aggregate interface

Maximum transmission unit (MTU) of an interface affects IP packets fragmentation and reassembly on the
interface.
To set the MTU for a Layer 3 aggregate interface:
Step
1. Enter system view.
2. Enter Layer 3 aggregate
interface or subinterface view.
3. Set the MTU for the Layer 3
aggregate interface or
subinterface.
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 caused by insufficient Selected ports on an aggregate link, you can set the minimum
number of Selected ports required for bringing up the specific 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 change to the Unselected state.
The link of the aggregate interface goes down.
When the minimum threshold is reached, the eligible member ports change to 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:
• Assigning two ports to an aggregation group.
Setting the maximum number of Selected ports to 1 for the aggregation group.
•
Then, only one Selected port is allowed in the aggregation group at any point in time, and the
Unselected port serves as a backup port.
To set the minimum and maximum numbers of Selected ports for an aggregation group:
