• Question 301:

  After finishing foundation on an AHV cluster, a consultant is preparing to plug into the customer network given the following set of requirements:

  1.

  All network traffic on trunks is tagged

  2.

  Customer is using LACP

  3.

  A native VLAN is not in use

  Which set of commands should the consultant use to ensure cluster connectivity on customer equipment?

  A. change_cvm_vlan 0 ovs-vsctl set port br0 tag=0 ovs-vsctl set port br0-up bond_mode=balance-tcp
  B. change_cvm_vlan 10 ovs-vsctl set port br0 tag=10 ovs-vsctl set port br0-up bond_mode=balance-tcp
  C. change_cvm_vlan 0 ovs~vsctl set port br0 tag=0 ovs~vsctl set port br0-up bond_mode=active-backup
  D. change_cvm_vlan 10 ovs-vsctl set port br0 tag=10 ovs-vsctl set port br0-up bond_mode=balance-slb
  B. change_cvm_vlan 10 ovs-vsctl set port br0 tag=10 ovs-vsctl set port br0-up bond_mode=balance-tcp

  ---

  Explanation/Reference:

  Considering the network configuration requirements--where all trunk traffic is tagged and a native VLAN is not used--the consultant must set up the CVM and bridge to operate with a specific VLAN tag. The command change_cvm_vlan 10 configures the Controller VM (CVM) to communicate over VLAN 10. The command ovs-vsctl set port br0 tag=10 applies VLAN 10 tagging to the bridge interface br0 , ensuring all traffic through it is appropriately tagged. The command ovsvsctl set port br0-up bond_mode=balance-tcp sets the bonding mode to balance-tcp , which is suitable for environments using LACP to optimize traffic distribution and redundancy across multiple physical links.References: Nutanix Community Documentation, Nutanix University Networking Best Practices.
