Chapter 7  Etherchannel Commands 
Etherchannel Commands are used to configure LAG and LACP function.   
LAG (Link Aggregation Group) is to combine a number of ports together to make a single 
high-bandwidth data path, which can highly extend the bandwidth. The bandwidth of the LAG is 
the sum of bandwidth of its member port.   
LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad and enables the dynamic link 
aggregation and disaggregation by exchanging LACP packets with its partner. The switch can 
dynamically group similarly configured ports into a single logical link, which will highly extend the 
bandwidth and flexibly balance the load. 
channel-group 
Description 
The channel-group command is used to add a port to the EtherChannel Group 
and configure its mode. To delete the port from the EtherChannel Group, please 
use no channel-group command. 
Syntax 
channel-group num mode { on | active | passive } 
no channel-group 
Parameter 
num  ——  The number of the EtherChannel Group, ranging from 1 to 14. 
on  ——  Enable the static LAG. 
active  ——  Enable the active LACP mode. 
passive  ——  Enable the passive LACP mode. 
Command Mode 
Interface Configuration Mode (interface fastEthernet / interface range 
fastEthernet / interface gigabitEthernet / interface range gigabitEhternet) 
Example 
Add the Fast Ethernet port 2-4 to EtherChannel Group 1 and enable the static 
LAG:
