LAG Configuration Options
This section documents some examples of setting options for the LAG. Be aware that
setting options on the LAG might also require you to set the corresponding value for
the peer Ethernet device’s LAG. configuration. For example, setting an MTU size on
the Oracle Fabric Interconnect side of the LAG requires you to set the corresponding
MTU size for the LAG on the peer device.
To set LAG options, no vNICs can be assigned to the port. As a result, if a port is
unassigned to a LAG, and you want to assign it to a LAG., you must:
1. Delete any vNICs supported by the port.
2. Add the port to the LAG.
3. Add the vNICs to the port.
-igmp-snooping= Specifies whether IGMP Snooping is enabled for the LAG.
-mode Specify access mode (access) or trunk mode (trunk) of
operation:
• In access mode, the LAG carries only transmitted or
received packets in the Access VLAN domain.
• In trunk mode, all VLAN traffic is transmitted or
received by the LAG.
-mtu= Sets the maximum size of packet transmitted without
fragmentation. Specify a number between 1500 and 9194.
By default (default) 1500-byte packets are used.
-rate= Sets the link speed to 100 Mbps (100m) or 1 Gbps (1g) or
allows for autonegotiation (autoNegotiate) between
the Oracle Fabric Interconnect port and the peer Ethernet
device. By default, autonegotiation (default) is used.
-tag-native= Specifies whether untagged packets are tagged with the
native VLAN ID (also called access VLAN ID) of the
source vNIC.
• By specifying true, you allow untagged packets to a be
tagged with the appropriate VLAN ID when they are
transmitted or received between the Oracle Fabric
Interconnect and its peer device.
• By specifying false, untagged packets are not tagged
with a VLAN ID.
-lacp-enable= Specifies an option which enables or disables LACP on
the LAG.
