Notifications

hh3cDhcp4ClientIpConflictAlm

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.242.3.0.1	The DHCP client obtains a conflicting IP address.	Error	Warning	1.3.6.1.4.1.25506.2.242.3.1.2 (hh3cDhcp4ClientIpConflictAlmRsm)	OFF

 

Notification triggers

This notification is generated when the DHCP client obtains an IP address that is in the same network segment as another interface address on the local device.

System impact

The DHCP client fails to obtain an IP address.

Status control

ON

CLI: Use the snmp-agent trap enable dhcp-client local-conflict command.

OFF

CLI: Use the undo snmp-agent trap enable dhcp-client local-conflict command.

Objects

OID (object name)	Description	Index nodes	Type	Value range
1.3.6.1.2.1.31.1.1.1.1 (ifName)	Interface name.	ifindex	DisplayString	Standard MIB values.
1.3.6.1.4.1.25506.2.242.1.1.1 (hh3cDhcp4ClientConflictIP)	Conflicting IP address assigned to the DHCP client.	N/A	InetAddressIPv4	Standard MIB values.

 

Recommended action

To resolve this issue:

1.     Use the display dhcp client command in any view to identify whether the DHCP client has obtained an IP address:

¡     If the DHCP client has obtained an IP address, no action is required.

¡     If the DHCP client has not obtained any IP address, use the display ip routing-table command to identify whether the assigned IP address is in the same network segment as the IP address of another interface.

-     If yes, change the IP address of the interface.

-     If no, proceed to step 2.

2.     If the issue persists, collect alarm information, log messages, and configuration data, and then contact H3C Support for help.

Notification triggers

This notification is generated when the DHCP client successfully requests a usable IP address after an IP address request failure.

System impact

No negative impact on services.

Status control

ON

CLI: Use the snmp-agent trap enable dhcp-client ip-apply-failed command.

hh3cDhcp4ClientApplyIpConflictAlm

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.242.3.0.5	The DHCP client obtains an IP address conflicting with the IP address of another host.	Informational	Warning	N/A	OFF

 

Notification triggers

This notification is generated when the DHCP client obtains an IP address that conflicts with the IP address of another host. The DHCP client detects for address conflicts by sending gratuitous ARP packets.

System impact

The DHCP client cannot obtain an IP address.

Status control

ON

CLI: Use the snmp-agent trap enable dhcp-client arp-conflict command.

OFF

CLI: Use the undo snmp-agent trap enable dhcp-client arp-conflict command.

Objects

OID (object name)	Description	Index nodes	Type	Value range

Recommended action

To resolve this issue:

1.     Use the display dhcp client command in any view to identify whether the DHCP client has obtained an IP address:

¡     If the DHCP client has obtained an IP address, no action is required.

¡     If the DHCP client has not obtained any IP address, use the display ip routing-table command to identify whether IP address conflicts occur in the network.

-     If multiple IP address conflicts exist, make a new network plan as a best practice.

-     If no, proceed to step 2.

2.     If the issue persists, collect alarm information, log messages, and configuration data, and then contact H3C Support for help.
