Dell EMC SmartFabric OS10 User Guide Release 10.5.0

The management address TLV advertises the IP address of the management interface to adjacent LAN devices. The system advertises this information in the management address TLV of all the physical ports. In a VLT domain, peer VLT devices transmit the IP address of their local management interface in the management address TLV.

To integrate with solutions such as the Cisco Application Centric Infrastructure (ACI), OS10 switches that are VLT peers, must advertise one common IP address in the management address TLV of the LLDPDU. This common IP address is also known as a virtual IP address, so that the VLT peers appear as a single switch to the Cisco ACI.

Configure OS10 switches that are part of a VLT pair to select a single IPv4 or IPv6 address as the virtual IP address. When you enable this feature, OS10 selects the lowest IP address per subnet that is configured on the management interface or management VLAN as the virtual IP address. LLDP advertises this virtual IP address in the management address TLV.
