The ESM tries to auto-enable the bonded NIC mode when it detects two management interfaces that are both using the same IP address. When bonded mode is enabled, both interfaces are assigned the same IP and MAC address. The bonding mode used is mode 0 (round-robin).

To disable NIC bonding, change the IP address of one of the interfaces so that it no longer matches the other. The system automatically disables the bonded NIC mode.

NOTE: Beginning with ESM 11.5.2, you can set the bonding mode in the UI by going to Network Settings, Main tab, Bonding mode. See resolved issue SIEM-27349 in the ESM 11.5.2 Release Notes.
