Step Command Remarks
2. Enter Layer 3 aggregate
interface or subinterface
view.
interface route-aggregation
{ interface-number |
interface-number.subnumber }
N/A
3. Configure the description
of the aggregate interface
or subinterface.
description text
By default, the description of an
interface is in the format of
interface-name Interface.
Configuring the MTU of a Layer 3 aggregate interface
Maximum transmission unit (MTU) of an interface affects IP packets fragmentation and reassembly on the
interface.
To change the MTU of a Layer 3 aggregate interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 3 aggregate
interface or subinterface view.
interface route-aggregation
{ interface-number |
interface-number.subnumber }
N/A
3. Configure the MTU of the Layer
3 aggregate interface or
subinterface.
mtu size The default setting is 1500 bytes.
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 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.
