Configuring a Layer 2 static aggregation group

Prerequisites

You must be in the global configuration context: switch(config)#

Procedure

Create a Layer 2 aggregate interface and access the Layer 2 aggregate interface view by entering:
```
switch(config)# interface lag <ID>
```
The range of the LAG interface ID is 1 to 256.

While creating the Layer 2 aggregate interface, the system automatically creates a Layer 2 static aggregation group numbered the same.
Set the operational state of every interface in the LAG to up by entering:
```
switch(config-lag-if)# no shutdown
```
NOTE:
This command does not impact the administrative state of the member interfaces because the command was entered at the level of the LAG. To change the administrative state of a member interface, enter the command at the interface level. For example:
```
switch(config)# interface 1/1/2
switch(config-if)# no shutdown
```
Disable routing by entering:
```
switch(config-lag-if)# no routing
```
See the Command-Line Interface Guide for your switch and software version for more information about the no routing command.

Assign a native VLAN ID to a trunk interface by entering:

switch(config-lag-if)# vlan trunk native <VLAN-ID>

For example:

switch(config-lag-if)# vlan trunk native 1

Use the following steps to add a maximum of eight interfaces to the LAG:
1. Assign an interface to the LAG:
```
switch(config-lag-if)# interface <PORT-ID>
```
  For example:
```
switch(config-lag-if)# interface 1/1/1
```
  See the Command-Line Interface Guide for your switch and software version for more information about the interface <PORT-ID> command.
2. Assign an ID to the LAG:
```
switch(config-if)# lag <ID>
```
  For example:
```
switch(config-if)# lag 100
```
3. Set the administrative state of the member interface to up:
```
switch(config-if)# no shutdown
```

View the configuration by entering:

switch(config-if)# show running-config

For example:

switch(config-if)# show running-config
Current configuration:

    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed all
interface 1/1/1
    no shutdown
    lag 100

Adding two interfaces to a Layer 2 static LAG

switch(config)# interface lag 100
switch(config-lag-if)# no shutdown
switch(config-lag-if)# no routing
switch(config-lag-if)# vlan trunk native 1
switch(config)# interface 1/1/1
switch(config-if)# lag 100
switch(config-if)# no shutdown
switch(config-if)# interface 1/1/2
switch(config-if)# lag 100
switch(config-if)# no shutdown
switch(config-if)# show running-config
Current configuration:
!
!Version ArubaOS-CX 10.02
