Configuring The Lag Interfaces As Dynamic; Setting The Lacp Long Timeout - Dell C9000 Series Networking Configuration Manual

Examples of Configuring a LAG Interface
The following example shows configuring a LAG interface.
Dell(conf)#interface port-channel 32
Dell(conf-if-po-32)#no shutdown
Dell(conf-if-po-32)#switchport
The LAG is in the default VLAN. To place the LAG into a non-default VLAN, use the tagged command on the
LAG.
Dell(conf)#interface vlan 10
Dell(conf-if-vl-10)#tagged port-channel 32

Configuring the LAG Interfaces as Dynamic

After creating a LAG, configure the dynamic LAG interfaces.
To configure the dynamic LAG interfaces, use the following command.
• Configure the dynamic LAG interfaces.
CONFIGURATION mode
port-channel-protocol lacp
Example of the port-channel-protocol lacp Command
Dell(conf)#interface Tengigabitethernet 3/15
Dell(conf-if-te-3/15)#no shutdown
Dell(conf-if-te-3/15)#port-channel-protocol lacp
Dell(conf-if-te-3/15-lacp)#port-channel 32 mode active
...
Dell(conf)#interface Tengigabitethernet 3/16
Dell(conf-if-te-3/16)#no shutdown
Dell(conf-if-te-3/16)#port-channel-protocol lacp
Dell(conf-if-te-3/16-lacp)#port-channel 32 mode active
...
Dell(conf)#interface Tengigabitethernet 4/15
Dell(conf-if-te-4/15)#no shutdown
Dell(conf-if-te-4/15)#port-channel-protocol lacp
Dell(conf-if-te-4/15-lacp)#port-channel 32 mode active
...
Dell(conf)#interface Tengigabitethernet 4/16
Dell(conf-if-te-4/16)#no shutdown
Dell(conf-if-te-4/16)#port-channel-protocol lacp
Dell(conf-if-te-4/16-lacp)#port-channel 32 mode active
The port-channel 32 mode active command shown here may be successfully issued as long as there is no
existing static channel-member configuration in LAG 32.

Setting the LACP Long Timeout

PDUs are exchanged between port channel (LAG) interfaces to maintain LACP sessions.
PDUs are transmitted at either a slow or fast transmission rate, depending upon 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. The default timeout value is 1 second. You can configure the default
Link Aggregation Control Protocol (LACP) 625
