Placing a LAG into a Non-default VLAN Force10(conf)#interface vlan 10 Force10(conf-if-vl-10)#tagged port-channel 32 Configure the LAG interfaces as dynamic After creating a LAG, configure the dynamic LAG interfaces. Figure 19-3 shows ports 3/15, 3/16, 4/15, and 4/16 added to LAG 32 in LACP mode with the command port-channel-protocol lacp. Figure 19-3. Creating a Dynamic LAG Example Force10(conf)#interface Gigabitethernet 3/15 Force10(conf-if-gi-3/15)#no shutdown Force10(conf-if-gi-3/15)#port-channel-protocol lacp Force10(conf-if-gi-3/15-lacp)#port-channel 32 mode active ...

Force10(conf)#interface Gigabitethernet 4/16 Force10(conf-if-gi-4/16)#no shutdown Force10(conf-if-gi-4/16)#port-channel-protocol lacp Force10(conf-if-gi-4/16-lacp)#port-channel 32 mode active The port-channel 32 mode active command shown above may be successfully issued as long as there is 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. Note: The 30-second timeout is available for dynamic LAG interfaces only. The lacp long-timeout command can be entered for static LAGs, but it has no effect. 372 | Link Aggregation Control Protoco
