In oVirt 4.2 we have introduced support for the Link Layer Discovery Protocol (LLDP). It is used by network devices for advertising the identity and capabilities to neighbors on a LAN. The information gathered by the protocol can be used for better network configuration. Learn more about LLDP.
When adding a host into oVirt cluster, the network administrator usually needs to attach various networks to it. However, a modern host can have multiple interfaces, each with its non-descriptive name.
In the screenshot below, taken from the Administration Portal, a network administrator has to know
to which interface to attach the network named m2
with VLAN_ID 162. Should it be interface
enp4s0
, ens2f0
or even ens2f1
? With oVirt 4.2, the administrator can hover over enp4s0
and see that this interface is connected to peer switch rack01-sw03-lab4
, and learn that this
peer switch does not support VLAN 162 on this interface. By looking at every interface, the
administrator can choose which interface is the right option for networkm2
.
A similar situation arises with the configuration of mode 4 bonding (LACP). Configurating LACP usually starts with network administrator defining a port group Continue reading
