Management network IP dependencies
Onboard Administrators management port allows external clients to connect through Onboard Administrator to iLOs and interconnect management processors that are configured to use Onboard Administrators internal management network
Onboard Administrator firmware bridges the client traffic to the enclosure from the management port to the internal enclosure management network if the destination IP address is not Onboard Administrator. Onboard Administrator creates a route table entry for each server iLO IP address in an enclosure. This allows Onboard Administrator to conduct IP communications with that iLO. These iLO route table entries enable you to configure each iLO network in a different subnet than Onboard Administrator. Each iLO is configured with a valid gateway on its subnet that is accessible through Onboard Administrators external management port connection. Routers are needed on the network connected to Onboard Administrator management port in order to provide the multiple subnets and gateways on the management network. Use of different subnets to attempt to isolate iLOs and Onboard Administrator management is not complete isolation of those networks.
