2 Configuring iLO Federation with the iLO web interface
Configuring iLO Federation
iLO uses multicast discovery, peer-to-peer communication, and iLO Federation groups to
communicate with other iLO systems.
•
Each multicast announcement is approximately 300 bytes, and you can configure the time
between announcements on the Group Configuration page.
•
iLO Federation groups allow iLO to encrypt and sign messages to other iLOs in the same
group.
•
iLO Federation groups can overlap, span racks and data centers, and group servers of the
same type.
•
An iLO system can be in up to 10 iLO Federation groups.
•
iLO systems in multiple locations can be managed together if the network is configured to
forward multicast traffic.
•
If you want to use server blades in an enclosure with iLO Federation, you must configure
Enclosure iLO Federation Support in the Onboard Administrator web interface. This feature is
supported in OA 4.11 or later. For more information, see
“Configuring enclosure support for
iLO Federation” (page 10) .
When data is loaded on an iLO Federation page in the iLO web interface, a request for data is
sent from the iLO system running the web interface to the iLO’s peers, and from those peers to
other peers, and so on until all of the data for the selected iLO Federation group is retrieved.
Use the iLO web interface on each iLO system to configure group memberships and multicast
options. The settings on the Group Configuration page apply to the local iLO system only. You
must configure these settings on each iLO system that will use the iLO Federation features.
TIP: You can use RIBCL XML scripts to view and configure group memberships and multicast
options for a batch of iLO systems. For more information, see “Configuring iLO Federation with
RIBCL scripts” (page 13) .
When you configure group memberships, you must specify the privileges that members of a group
have over the local managed server. For example, if you add the local iLO system to group1, and
assign the Virtual Power and Reset privilege, the users of other iLO systems in group1 can use the
Group Power features to change the power state of the managed server. If the local iLO system
does not grant the Virtual Power and Reset privilege to a group, then the users of other iLOs in the
group cannot use the Group Power features to change the power state of the managed server. If
the iLO Security Override Switch is set on the managed server, the users of other iLOs in group1
can use any iLO Federation feature to change the state of the server, regardless of the assigned
group privileges.
All iLO systems are automatically added to the DEFAULT group, which is granted the Login privilege
for each group member. You can edit or delete the DEFAULT group membership.
For information about using iLO Federation, see “Using iLO Federation” (page 5) .
iLO Federation network requirements
When you use iLO Federation, note the following network requirements:
•
The iLO Federation features are not supported with the iLO Shared Network Port configuration.
•
iLO Federation supports both IPv4 and IPv6.
