Configuring an Ethernet Physical Interface
To configure a member link, perform the following steps:
1.
Specify a Fast Ethernet or Gigabit Ethernet interface for which you want to create
a member link.
host1(config)# interface gigabitEthernet 2/0
2.
Configure LACP in passive or active mode.
host1(config-if)# lacp active
3.
Specify the speed and the duplex mode for the Ethernet interface.
host1(config-if)# speed 100
host1(config-if)# duplex full
4.
Specify the MTU.
host1(config-if)# mtu 9000
5.
To configure additional member links, repeat steps 1 through 4.
NOTE: All of the member links that you configure must be on the same line module
and have the same physical layer characteristics, such as speed, duplex mode, and
MTU.
Configuring a LAG Bundle
To configure a LAG bundle and add member links, perform the following steps:
1.
Create the LAG bundle.
host1(config)# interface lag bundleBoston
2.
Add a member link to the LAG bundle.
host1(config-if)# member–interface gigabitEthernet 2/0
3.
(Optional) Configure the minimum number of member links required in the LAG
bundle for the LAG interface to be considered up.
host1(config-if)# minimum-links 2
