Version 6.8 405 Mediant 2600 E-SBC
User's Manual 24. HA Overview
Notes:
• Switchover triggered by loss of physical connectivity in one or more Ethernet port-
group is not done if the active device has been set to a Revertive priority level of
10. In such a scenario, the device remains active despite the loss of connectivity in
one or more of its Ethernet port groups.
• After HA switchover, the active device updates other hosts in the network about
the new mapping of its Layer-2 hardware address to the global IP address, by
sending a broadcast gratuitous Address Resolution Protocol (ARP) message.
