HH3C-LLDP-EXT-MIB

About this MIB

The Link Layer Discovery Protocol (LLDP) is a Layer 2 industry-standard protocol (IEEE 802.1AB) that allows network devices from different vendors to discover neighbors and exchange system and configuration information.

This MIB defines private MIB objects for the following extended LLDP management features:

● Global LLDP configuration:

  - Global status of LLDP.

  - Global status of CDP compatibility.

● LLDP port configuration:

  - Port-specific packet transmission settings of CDP-compatible LLDP.

  - Protection action taken on ports whose neighbors fail validation.

  - Protection action taken on ports whose neighbors age out.

● LLDP neighbor validation criteria:

  - Chassis ID subtype.

  - Chassis ID.

  - Port ID subtype.

  - Port ID.

● Feature status on LLDP-enabled ports:

  - Neighbor validation status.

  - Neighbor aging status.

● Trapping configuration on LLDP-enabled ports:

  - Trapping for neighbor validation status changes.

  - Trapping for neighbor aging status changes.

Notifications

hh3clldpValidationStatusChange

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.100.2.0.1	Neighbor validation status changes.	Informational	Warning	-	OFF

 

Notification triggers

LLDP neighbor validation enables a port to validate the identity of the neighbor based on the neighbor validation criteria configured on the port. Each incoming LLDP packet must match all the validation criteria configured on the port. If the neighbor information in a packet does not match the criteria, the system shuts down the data link layer and disables data transmission on the port.

System impact

No negative impact on services.

Status control

ON

CLI: Use the lldp neighbor-protection validation command.

OFF

CLI: Use the undo lldp neighbor-protection validation command.

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.4.1.25506.2.100.1.1.5.1.1 (hh3clldpPortStatusPortNum)	Port index.	hh3clldpPortStatusPortNum	LldpPortNumber	Standard MIB values.
1.3.6.1.4.1.25506.2.100.1.1.5.1.2 (hh3clldpPortValidationStatus)	Neighbor validation status.	hh3clldpPortStatusPortNum	Integer32	Standard MIB values.

 

Recommended action

1.Verify that the neighbor matches all neighbor validation criteria configured on the port.

2.If the neighbor does not match all neighbor validation criteria configured on the port, notify the administrator of the neighbor to configure LLDP related settings to establish the LLDP neighbor relationship.

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

hh3clldpAgingStatusChange

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.100.2.0.2	Neighbor aging status changes.	Informational	Warning	N/A (N/A)	OFF

 

Notification triggers

The system blocks or shuts down an LLDP neighbor aging-enabled port if the neighbor on the port ages out.

System impact

No negative impact on services.

Status control

ON

CLI: Use the lldp neighbor-protection aging { block | shutdown } command.

OFF

CLI: Use the undo lldp neighbor-protection aging command.

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.4.1.25506.2.100.1.1.5.1.1 (hh3clldpPortStatusPortNum)	Port index.	hh3clldpPortStatusPortNum	LldpPortNumber	Standard MIB values.
1.3.6.1.4.1.25506.2.100.1.1.5.1.3 (hh3clldpPortAgingStatus)	Neighbor aging status.	N/A	Integer32	Standard MIB values.

 

Recommended action

Identify whether a neighbor has aged out.

hh3clldpGlobalEnableStatus

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.100.2.0.3	Enabling status of LLDP changes globally.	Informational	Warning	-	ON

 

Notification triggers

This notification is generated when the enabling status of LLDP changes globally.

System impact

No negative impact on services.

Status control

ON

CLI: Use the lldp global enable command.

OFF

CLI: Use the undo lldp global enable command.

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.4.1.25506.2.100.1.1.1 (hh3clldpAdminStatus)	Enabling status of LLDP on the device.	N/A	TruthValue	Standard MIB values.

 

Recommended action

LLDP takes effect on a port only when LLDP is enabled both globally and on the port.

hh3clldpgLocManAddrChange

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.100.2.0.4	Management address advertised by LLDP changes.	Informational	Warning	-	ON

 

Notification triggers

This notification is generated when the management address advertised by LLDP changes.

System impact

No negative impact on services.

Status control

ON

CLI: Use the lldp tlv-enable basic-tlv management-address-tlv command.

OFF

CLI: Use the undo lldp tlv-enable basic-tlv management-address-tlv command.

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.4.1.25506.2.100.3.1 (hh3clldpManAddr)	Management address.	N/A	OCTET STRING	Standard MIB values.

 

Recommended action

If the LLDP management address to be advertised is incorrect, execute the lldp tlv-enable basic-tlv management-address-tlv command on the port to change the LLDP management address to be advertised.
