HH3C-SESSION-MIB

About this MIB

Use this MIB to configure session modules and obtain session messages.

MIB file name

hh3c-session.mib

Notifications

hh3cSessionDrvMaxTrap

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.149.1.3.0.1	Hardware session resource exhaustion.	Error	Major	1.3.6.1.4.1.25506.2.149.1.3.0.2 (hh3cSessionDrvRecoveryTrap)	OFF

 

Notification triggers

This notification is generated when the number of sessions on the device reaches the upper limit.

System impact

New sessions initiated by the CGN device cannot be forwarded by hardware. Too many new sessions might increase CPU usage.

Status control

ON

CLI: Use the snmp-agent trap enable session resource command.

OFF

CLI: Use the undo snmp-agent trap enable session resource command.

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.4.1.25506.2.149.1.3.1.1  (hh3cSessionDrvNum)	Maximum number of sessions supported by hardware.	N/A	Unsigned32	Standard MIB values.
1.3.6.1.4.1.25506.2.149.1.3.1.2  (hh3cSessionChassis)	Chassis number.	N/A	Unsigned32	(0..65534)
1.3.6.1.4.1.25506.2.149.1.3.1.3  (hh3cSessionSlot)	Slot number.	N/A	Unsigned32	(0..65534)
1.3.6.1.4.1.25506.2.149.1.3.1.4 (hh3cSessionCpu)	CPU number.	N/A	Unsigned32	(0..7)

 

Recommended action

To resolve this issue:

1.Execute the display session table { ipv4 | ipv6 } command to verify whether the number has reached the upper limit.

  - If the upper limit is reached, expand the device capacity to store more sessions and verify whether the alarm is removed. If the alarm is not removed, go to the next step.

  - If the upper limit is not reached, go to the next step.

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

hh3cSessionDrvRecoveryTrap

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.149.1.3.0.2	Number of sessions drops below the limit.	Recovery	Warning	-	OFF

 

Notification triggers

This notification is generated if the number of sessions on the device drops below the limit supported by hardware.

System impact

No negative impact on the system.

Status control

ON

CLI: Use the snmp-agent trap enable session resource command.

OFF

CLI: Use the undo snmp-agent trap enable session resource command.

Recommended action

No action is required.

hh3cSessionThdMaxTrap

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.149.1.3.0.3	High hardware session resource usage.	Error	Major	1.3.6.1.4.1.25506.2.149.1.3.0.4 (hh3cSessionThdRecoveryTrap)	OFF

 

Notification triggers

This notification is generated if the hardware session resource usage exceeds the alarm threshold.

System impact

No impact is generated on services upon the triggering of the notification. However, if new sessions continue to be created and the number of sessions reaches the upper limit, the new sessions cannot be forwarded by hardware and too many new sessions might increase CPU usage.

Status control

ON

CLI: Use the snmp-agent trap enable session resource command.

OFF

CLI: Use the undo snmp-agent trap enable session resource command.

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.4.1.25506.2.149.1.3.1.5  (hh3cSessionUsage)	Hardware session resource usage.	N/A	Unsigned32	(0..100)
1.3.6.1.4.1.25506.2.149.1.3.1.6  (hh3cSessionThreshold)	Alarm threshold.	N/A	Unsigned32	(60..90)

1.3.6.1.4.1.25506.2.149.1.3.1.4 (hh3cSessionCpu)	CPU number.	N/A	Unsigned32	(0..7)

 

Recommended action

To resolve this issue:

1.Execute the display session table { ipv4 | ipv6 } command to verify whether the resource usage has exceeded the alarm threshold.

  - If the alarm threshold is exceeded, go to step 2.

  - If the alarm threshold is not exceeded, go to step 3.

2.Execute the session alarm usage threshold command to increase the alarm threshold or expand the device capacity to store more sessions. Verify whether the alarm is removed. If the alarm is not removed, proceed to step 3.

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