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)#接口延迟
```
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:
这个命令是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 1/1/2switch(config-if)#no shutdown
```
On the 8320, 8325, 8360, and 8400, disable routing by entering:
```
switch(config-lag-if)#no routing
```
See theCommand-Line Interface Guidefor your switch and software version for more information about theno routingcommand.

NOTE:
On the 6100 and 6200 Switch Series, routing is not supported on physical interfaces.

On the 6300 and 6400 Switch Series, routing is disabled by default.

Assign a native VLAN ID to a trunk interface on the LAG 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 16 interfaces to the LAG:
1. To assign an interface to the LAG:
```
switch(config-lag-if)#interface
```
  To assign a range of interfaces to a LAG:
```
switch(config-lag-if)#interface-
```
  For example:
```
switch(config-lag-if)#interface 1/1/1-1/1/4
```
  See theCommand-Line Interface Guidefor your switch and software version for more information about theinterface command.
2. Assign an ID to the LAG:
```
switch(config-if)#lag
```
  For example:
```
switch(config-if-<1/1/1-1/1/4>)#滞后100
```
3. Set the administrative state of the member interface to up:
```
switch(config-if-<1/1/1-1/1/4>)#no shutdown
```

View the configuration by entering the following:

For 6100, 6200, 6300, and 6400 switch series:

switch(config-if-<1/1/1-1/1/4>)#show running-configCurrent configuration: ! vlan 1 interface lag 100 no shutdown vlan trunk native 1 vlan trunk allowed all interface 1/1/1 no shutdown lag 100 interface 1/1/2 no shutdown lag 100 interface 1/1/3 no shutdown lag 100 interface 1/1/4 no shutdown lag 100 switch(config-if-<1/1/1-1/1/4>)#show lacp aggregatesAggregate name : lag100 Interfaces : 1/1/3 1/1/1 1/1/4 1/1/2 Heartbeat rate : N/A Hash : l3-src-dst Aggregate mode : Off

For 8320, 8325, 8360, and 8400 switch series:

switch(config-if-<1/1/1-1/1/4>)#show running-configCurrent configuration: ! vlan 1 interface lag 100 no shutdown no routing vlan trunk native 1 vlan trunk allowed all interface 1/1/1 no shutdown lag 100 interface 1/1/2 no shutdown lag 100 interface 1/1/3 no shutdown lag 100 interface 1/1/4 no shutdown lag 100 switch(config-if-<1/1/1-1/1/4>)#show lacp aggregatesAggregate name : lag100 Interfaces : 1/1/3 1/1/1 1/1/4 1/1/2 Heartbeat rate : N/A Hash : l3-src-dst Aggregate mode : Off
