To ensure that multicast discovery works correctly, make sure that all iLO systems in the same group
use the same value for Multicast Time to Live (TTL).

Network changes and changes you make on this page take effect after the next multicast
announcement.
Multicast options
• iLO Federation Management—Enables or disables the iLO Federation features. The default setting
is Enabled. Selecting Disabled disables the iLO Federation features for the local iLO system.
• Multicast discovery—Enables or disables multicast discovery. The default setting is Enabled.
Selecting Disabled disables the iLO Federation features for the local iLO system.
Disabling multicast discovery is not supported on Synergy compute modules. To limit the impact of
multicast traffic on a network with Synergy compute modules, adjust the IPv6 Multicast Scope and
Multicast Time To Live (TTL) settings.
• Multicast Announcement Interval (seconds/minutes)—Sets the frequency at which the iLO system
announces itself on the network. Each multicast announcement is approximately 300 bytes. Select a
value of 30 seconds to 30 minutes. The default value is 10 minutes. Selecting Disabled disables the
iLO Federation features for the local iLO system.
• IPv6 Multicast Scope—The size of the network that will send and receive multicast traffic. Valid
values are Link, Site, and Organization. The default value is Site.
• Multicast Time To Live (TTL)—Specifies the number of switches that can be traversed before
multicast discovery stops. The default value is 5.
iLO Federation groups
iLO Federation group memberships for local iLO systems
When you configure group memberships for a local iLO system, you specify the privileges that members
of a group have for configuring 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 change the power state of the managed server.
If the local iLO system does not grant the Virtual Power and Reset privilege to group1, the users of other
iLO systems in group1 cannot use the group power control features to change the power state of the
managed server.
If the system maintenance switch is set to disable iLO security on the local iLO system, the users of other
iLO systems in group1 can change the state of the managed server, regardless of the assigned group
privileges.
Group memberships for the local iLO system are configured on the iLO Federation page Setup tab.
You can perform the following tasks for a local iLO system:
• View group memberships.
• Add and edit group memberships.
• Remove group memberships.
