Configuring a Layer 3 static aggregation group

Create a Layer 3 aggregate interface and access the Layer 3 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 3 aggregate interface, the system automatically creates a Layer 3 static aggregation group numbered the same.

Set the operational state of every interface in the LAG to up by entering:

For 6300 and 6400 switch series:
```
switch(config-lag-if)#no shutdownswitch(config-lag-if)#routing
```
NOTE:
这个命令不会影响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 shutdownswitch(config-if)#routing
```
For 8320, 8325, 8360, and 8400 switch series:
```
switch(config-lag-if)#no shutdown
```
NOTE:
这个命令不会影响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
```

Set the IP address on the LAG interface by entering:

switch(config-lag-if)#ip address/

For example:

switch(config-lag-if)#ip address 192.0.2.1/30

Use the following steps to add a maximum of 16 interfaces to the LAG:

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.

Assign an ID to the LAG:

switch(config-if)#lag

For example:

switch(config-if-<1/1/1-1/1/4>)#滞后100

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 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 routing ip address 192.0.2.1/30 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
