contacted through the Shared Network Port. When you use iLO NIC auto-selection, you can install a
server in either data center and iLO will select the correct network port.
By default, NIC auto-selection is disabled.

NIC auto-selection support
•
ProLiant Gen10 nonblade servers support NIC auto-selection.
•
iLO 5 can be configured to search both Shared Network Ports on servers that support this
configuration.
•
iLO 5 supports NIC failover. When enabled, iLO automatically begins searching for a NIC connection
when the current connection fails. NIC auto-selection must be enabled to use this feature.
iLO startup behavior with NIC auto-selection enabled
When NIC auto-selection is enabled:
•
If iLO was just connected to power, it tests the iLO Dedicated Network Port first.
•
If iLO was just reset, it tests the last used iLO network port first.
•
When testing a network port, if iLO detects network activity, then that port is selected for use. If
network activity is not found after approximately 100 seconds, iLO switches to the opposite network
port and begins testing there. iLO alternates testing between the iLO Dedicated Network Port and the
iLO Shared Network Port until network activity is detected. An iLO reset occurs each time iLO switches
between network ports for testing purposes.
CAUTION:
If any of the physical NICs are connected to an unsecured network, unauthorized access
attempts might occur when iLO is alternating between the iLO network ports. Hewlett Packard
Enterprise strongly recommends that whenever iLO is connected to any network:
◦
Use strong passwords for iLO access.
◦
Never connect the iLO Dedicated Network Port to an unsecured network.
◦
If the iLO Shared Network Port is connected to an unsecured network, use VLAN tagging on
the iLO portion of the shared NIC, and make sure that the VLAN is connected to a secure
network.
•
When iLO searches for an active network port, the server UID LED is illuminated. If iLO is reset during
the search, the UID LED flashes for 5 seconds and then is illuminated until an active port is selected or
iLO is reset.
•
When a server supports both LOM and FlexibleLOM Shared Network Port connections to iLO, iLO will
test only the option that was selected during configuration. It will not alternate testing between LOM
and FlexibleLOM options.
•
If NIC auto-selection is configured to search for DHCP address assignment activity, but only one of the
iLO network ports has DHCP enabled, iLO tests for received data packet activity on the port that is not
configured for DHCP.
