ipArpEntryUpdated:arpnd

Table 1. ipArpEntryUpdated properties
Property name	Value
Application name	arpnd
Event name	ipArpEntryUpdated
Default severity	informational
Message format string	The ARP entry for ipv4-address on interface.subinterface-index has been updated from mac old-mac type old-type to mac new-mac and type new-type.
Cause	This event is generated whenever an existing static or dynamic ARP entry for an IPv4 address is overwritten. This could be a triggered by a change of entry type (static vs dynamic) or a change of MAC address or a change of the subinterface binding.
Effect	None

ipSubinterfaceDuplicateIpv4Address:arpnd

Table 2. ipSubinterfaceDuplicateIpv4Address properties
Property name	Value
Application name	arpnd
Event name	ipSubinterfaceDuplicateIpv4Address
Default severity	notice
Message format string	The IPv4 address ipv4-address assigned to interface.subinterface-index is being used by another host or router on the same subnet.
Cause	This event is generated when ARP detects that another system is using the same IPv4 address
Effect	Unreliable communications

ipSubinterfaceDuplicateIpv6Address:arpnd

Table 3. ipSubinterfaceDuplicateIpv6Address properties
Property name	Value
Application name	arpnd
Event name	ipSubinterfaceDuplicateIpv6Address
Default severity	notice
Message format string	The IPv6 address ipv6-address assigned to interface.subinterface-index is being used by another host or router on the same subnet.
Cause	This event is generated when IPv6 DAD detects that another system is using the same IPv6 address
Effect	Unreliable communications

ipSubinterfaceDuplicateMacAddress:arpnd

Table 4. ipSubinterfaceDuplicateMacAddress properties
Property name	Value
Application name	arpnd
Event name	ipSubinterfaceDuplicateMacAddress
Default severity	notice
Message format string	The MAC address mac-address used by interface.subinterface-index is being used by another host or router on the same subnet.
Cause	This event is generated when ARP or IPv6 Neighbor Discovery detects that another system is using the same MAC address
Effect	Unreliable communications

ipSubinterfaceInvalidArp:arpnd

Table 5. ipSubinterfaceInvalidArp properties
Property name	Value
Application name	arpnd
Event name	ipSubinterfaceInvalidArp
Default severity	notice
Message format string	An ARP request for ipv4-address was received on interface.subinterface-index and there is no matching IPv4 subnet.
Cause	This event is generated when ARP receives an ARP request for an invalid IPv4 address
Effect	None

Property name	Value
Application name	arpnd
Event name	ipSubinterfaceInvalidIpv6NeighborSolicitation
Default severity	notice
Message format string	An IPv6 neighbor solicitation for ipv6-address was received on interface.subinterface-index and there is no matching IPv6 subnet.
Cause	This event is generated when IPv6 neighbor discovery receives a NS message for an invalid IPv6 address
Effect	None

ipv6NeighborEntryUpdated:arpnd

Table 7. ipv6NeighborEntryUpdated properties
Property name	Value
Application name	arpnd
Event name	ipv6NeighborEntryUpdated
Default severity	informational
