Interfaces
Create a LAG and then add LAG member interfaces. By default, all interfaces are in no shutdown and switchport modes.
1. Create a LAG in CONFIGURATION mode.
interface port-channel port-channel number
2. Enter INTERFACE mode.
interface ethernet node/slot/port[:subport]
3. Set the channel group mode to Active in INTERFACE mode.
channel-group number mode active
Configure dynamic LAG interfaces
OS10(config)# interface port-channel 10
OS10(conf-if-po-10)# exit
OS10(config)# interface ethernet 1/1/10
OS10(conf-if-eth1/1/10)# no switchport
OS10(conf-if-eth1/1/10)# channel-group 10 mode active
OS10(conf-if-eth1/1/10)# exit
OS10(config)# interface ethernet 1/1/11
OS10(conf-if-eth1/1/11)# no switchport
OS10(conf-if-eth1/1/11)# channel-group 10 mode active
Rates
Protocol data units (PDUs) are exchanged between port-channel (LAG) interfaces to maintain LACP sessions. PDUs are
transmitted at either a slow or fast transmission rate, depending on the LACP timeout value. The timeout value is the amount of
time that a LAG interface waits for a PDU from the remote system before bringing the LACP session down.
By default, the LACP rate is normal (long timeout). If you configure a fast LACP rate, a short timeout sets.
Set the LACP rate in CONFIGURATION mode.
