Description: Cisco UCS extvmm:VMNetworkDefinition:dn managed object property

What is cucsExtvmmVMNetworkDefinitionDn?

This is the distinguished name of a specific VM Network Definition -- the template specifying a VLAN, its IP pool, and port limits -- that UCS Manager uses to generate actual VM network port groups in vCenter. Because one definition can be referenced by multiple VM networks or network-set entries, this Dn is the single source of truth an admin edits to change a VLAN's parameters, with the effect propagating out to every port group generated from this specific definition. A Dn like 'sys/vm-network-defs/def-vlan210' identifies the template that defines VLAN 210's parameters for VM-FEX.
