A 502 error is displayed on the Multi-System Map page
Issue: The Multi-System Map page shows a 502 error.
This error indicates that the listed peer rejected a request from the local iLO.
Suggested action: Ensure that communication between the local iLO and the peer with the error is
not blocked by an intermediate firewall or a change to the iLO network configuration and HTTP
port setting.
A 403 error is displayed on the Multi-System Map page
Issue: The Multi-System Map page shows a 403 Forbidden/Authorization error.
This error occurs when the group key on the local iLO does not match the group key on a peer
iLO.
Suggested action: Ensure that the group key matches for all of the iLOs that are members of the
selected group.
iLO peers are not displayed
Issue: iLO peers (systems in the same group as the local iLO) are not displayed on iLO Federation
pages.
Suggested action 1: Ensure that the group key matches for all of the iLOs that are members of the
selected group.
Suggested action 2: Wait for twice the configured multicast interval, and then refresh the iLO
Federation page. If an iLO system was reconfigured and can no longer communicate with the local
iLO, it will be dropped its from its peer relationships after they expire, which should eliminate the
query error.
Suggested action 3: If you are using server blades in an enclosure, verify that Enclosure iLO
Federation Support is configured on the Enclosure Settings
→Network Access→Protocols page in
the Onboard Administrator web interface. You must have OA 4.11 or later to configure this setting.

“Configuring enclosure support for iLO Federation” (page 10) .
Suggested action 4: Verify that the switches on the network are configured to allow communication
between iLO peers. For more information, see
“iLO Federation network requirements” (page 7) .
Suggested action 5: Ensure that communication between the local iLO and the peer with the error
is not blocked by an intermediate firewall or a change to the iLO network configuration and HTTP
port setting.
iLO peers are displayed with IPv6 addresses on IPv4 networks
Issue: iLO peers on an IPv4 network are displayed with IPv6 addresses on iLO Federation pages.
Suggested action: If the network is configured to use IPv4 only, verify that the iLO Client Applications
use IPv6 first check box is not selected on the iLO Dedicated Network Port
→IPv6 page.
