Specifying ignored VLANs on a Layer 2 aggregate interface
By default, to become Selected ports, the member ports must have the same VLAN permit state and
VLAN tagging mode as the corresponding Layer 2 aggregate interface.
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
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter Layer 2 aggregate
interface view.
interface bridge-aggregation
interface-number
N/A
3.
Configure ignored VLANs.
link-aggregation ignore vlan
vlan-id-list
By default, a Layer 2 aggregate
interface does not ignore any
VLANs.
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.

2.
Enter Layer 3 aggregate
interface or subinterface view.
interface route-aggregation

interface-number.subnumber
}
N/A
3.
Configure the MTU of the
Layer 3 aggregate interface
or subinterface.

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:
