Shared LOM EXT mode enables the 1-Gb/10-Gb Ethernet ports and the ports on any installed Cisco virtual interface card (VIC) to access the Cisco Integrated Management Interface (Cisco IMC). If you want to use the 10/100/1000 dedicated management ports to access Cisco IMC, you can connect to the node and change the NIC mode as described in Setting Up the Node With the Cisco IMC Configuration Utility.
Set the CIMC server to factory default settings before integrating with Cisco UCS Manager.
Do not connect dedicated CIMC ports to the network for integrated nodes. Doing so causes the server to not be discovered in Cisco UCS Manager. If the server is not discovered, reset CIMC to factory settings for each server.
