Configure The Lag Interfaces As Dynamic; Set The Lacp Long Timeout - Dell Force10 S4810P Configuration Manual

The LAG is in the default VLAN. To place the LAG into a non-default VLAN, use the
on the LAG as shown in the example below:
FTOS(conf)#interface vlan 10
FTOS(conf-if-vl-10)#tagged port-channel 32

Configure the LAG interfaces as dynamic

After creating a LAG, configure the dynamic LAG interfaces. The following example shows ports 3/15, 3/
16, 4/15, and 4/16 added to LAG 32 in LACP mode with the command
FTOS(conf)#interface Gigabitethernet 3/15
FTOS(conf-if-gi-3/15)#no shutdown
FTOS(conf-if-gi-3/15)#port-channel-protocol lacp
FTOS(conf-if-gi-3/15-lacp)#port-channel 32 mode active
...
FTOS(conf)#interface Gigabitethernet 3/16
FTOS(conf-if-gi-3/16)#no shutdown
FTOS(conf-if-gi-3/16)#port-channel-protocol lacp
FTOS(conf-if-gi-3/16-lacp)#port-channel 32 mode active
...
FTOS(conf)#interface Gigabitethernet 4/15
FTOS(conf-if-gi-4/15)#no shutdown
FTOS(conf-if-gi-4/15)#port-channel-protocol lacp
FTOS(conf-if-gi-4/15-lacp)#port-channel 32 mode active
...
FTOS(conf)#interface Gigabitethernet 4/16
FTOS(conf-if-gi-4/16)#no shutdown
FTOS(conf-if-gi-4/16)#port-channel-protocol lacp
FTOS(conf-if-gi-4/16-lacp)#port-channel 32 mode active
The
port-channel 32 mode active
no existing static channel-member configuration in LAG 32.

Set 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; it can be configured to be 30 seconds.
Invoking the longer timeout might prevent the LAG from flapping if the remote system is up but
temporarily unable to transmit PDUs due to a system interruption.
The 30-second timeout is available for dynamic LAG interfaces only. The
Note:
command can be entered for static LAGs, but it has no effect.
