INTERFACE takeover_interface_name HAS TAKEN OVER ND RESPONSIBILITY FOR INACTIVE INTERFACE inactive_interface_name

Explanation

An interface became inactive and TCP/IP detected another active interface on the same physical network that can take over Neighbor Discovery (ND) responsibility for the inactive interface.

takeover_interface_name is the name of the interface that took over the ND responsibility.

inactive_interface_name is the name of the inactive interface.

System action

TCP/IP assigns ND responsibility for the inactive interface to the takeover interface. TCP/IP sends a gratuitous neighbor advertisement for the IP address of the inactive interface and uses the takeover interface to reply to neighbor solicitation requests on behalf of the inactive interface. If the inactive interface becomes active again, TCP/IP will reassign the ND responsibility to that interface.

Operator response

None.

System programmer response

None.

Module

TCPIP

Procedure name

EZBIFIND
