According to section 4 of the exam blueprint guide1, one of the topics covered is AHV networking components and configuration settings. One of these components is Open vSwitch (OVS), which is a software switch that provides network connectivity between VMs and physical networks. OVS has two types of ports:
Uplink ports: These are physical ports that connect to external networks or switches.
Internal ports: These are virtual ports that connect to VMs or other internal networks.
To view the uplink state of all AHV nodes in the cluster, an administrator can use the manage_ovs command with the show_uplinks option. This command displays information such as port name, link state, speed, duplex mode, MTU size, bond mode, and bond status. However, this command only works on a single node. To run the command on all nodes in the cluster, an administrator can use the allssh command, which executes a command on all CVMs in parallel. Therefore, the correct command is:
allssh manage_ovs show_uplinks
