Which parameter is missing from this command?

A consultant creates a four-node AHV cluster with two 1GbE (eth0, etc1) and two 10GbE (eth2, eth3) NICs per node. The 1GbE NICs will not be placed into service, but the customer wants the network to be preconfigured for their eventual use.

The consultant removes the 1GbE NIC from the default bond and creates a second bridge(br1), but is unable to add the 1GbE NIC using the below command:

manage_ovs Cbridge_name br1 Cinterfaces 1g Cbond_name br1-up update_uplinks

A . –bond_duplex full
