Notifications

hh3cRadiusAuthServerUpTrap

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.13.3.0.1	Authentication server up	Recovery	Warning	N/A (N/A)	OFF

 

Notification triggers

This notification is generated when the status of an authentication server changes from blocked to active.

This notification cannot function correctly with SNMPv2 and later versions. It has been replaced with hh3cRadiusAuthenticationServerUpTrap (1.3.6.1.4.1.25506.2.13.3.0.4) in SNMPv2 and later versions.

The notification generated by the device for the RADIUS authentication server up event (if enabled) depends on the SNMP version for the event:

If SNMPv1 is specified for this event by using the radius trap-version v1 command, the device generates the hh3cRadiusAuthServerUpTrap (1.3.6.1.4.1.25506.2.13.3.0.1) notification.

If SNMPv2 is specified for this event by using the radius trap-version v2 command, the device generates the hh3cRadiusAuthenticationServerUpTrap (1.3.6.1.4.1.25506.2.13.3.0.4) notification.

System impact

No negative impact on services.

Status control

ON

CLI: Use both the snmp-agent trap enable radius authentication-server-up and radius trap-version v1 commands.

OFF

CLI: Use either the undo snmp-agent trap enable radius authentication-server-up command or the radius trap-version v2 command.

Recommended action

To resolve this issue:

1.Use the display interface command to view whether the interface connected to the authentication server is up:

  - If yes, go to step 2.

2.Use the ping command to check whether the RADIUS server is reachable:

  - If no, first check the network reachability between the device and the RADIUS server, and then check whether firewalls exist in the network. Make sure the RADIUS server is reachable.

  - If yes, go to step 3.

3.Use the display current-configuration command to view whether the RADIUS server's configurations are correct:

  - If no, modify the RADIUS server's configurations. For more information about RADIUS server configurations, see AAA commands in Security Command Reference and AAA configuration in Security Configuration Guide of the device.

  - If yes, go to step 4.

4.Collect alarm information, log messages, and configuration data, and then contact H3C Support for help.

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.13.8.0.1	The ratio of the number of buffered stop-accounting packets to the max number allowed reached the upper threshold.	Error	Warning	1.3.6.1.4.1.25506.2.13.8.0.2 (hh3cRadiusAccCacheResume)	OFF

 

Notification triggers

This notification is generated when the ratio of the number of buffered stop-accounting packets to the allowed max number configured by using the radius stop-accounting-buffer cache command reaches the upper threshold.

System impact

No negative impact on services currently. If the number of buffered stop-accounting packets reaches the allowed max number, the device processes new stop-accounting requests according to whether you have configured the radius stop-accounting-buffer overwrite-oldest command in system view for new stop-accounting request overwriting.

If you have configured the command, the device uses a new stop-accounting request to overwrite the oldest one.

If you have not configured the command, the device stops buffering new stop-accounting requests and new stop-accounting requests are dropped.

Status control

ON

CLI: Use the snmp-agent trap enable radius accounting-cache-upper-threshold command.

OFF

CLI: Use the undo snmp-agent trap enable radius accounting-cache-upper-threshold command.

Recommended action

To resolve this issue:

1.Check whether the set upper threshold for stop-accounting request buffering is appropriate:

  - If yes, go to step 2.

  - If no, use the radius stop-accounting-buffer warning-threshold command in system view to set the upper threshold to a higher value as needed, and then go to step 2.

2.Use the test-aaa command in user view to test whether communication failures exist between the device and the RADIUS server:

  - If the test succeeds, it indicates that the RADIUS server is reachable. Go to step 3.

  - If the test fails, troubleshoot the link between the device and the server. If the issue persists when the link is normal, go to step 3.

3.Collect alarm information, log messages, and configuration data, and then contact H3C Support for help.

Notification triggers

This notification is generated when the ratio of the number of buffered stop-accounting packets to the allowed max number configured by using the radius stop-accounting-buffer cache command drops below the lower threshold.

Notification triggers

This notification is generated when the system drops buffered stop-accounting packets or stop-accounting packets to be buffered after the memory usage reaches the minor alarm threshold.

System impact

The device processes stop-accounting packets according to whether you have configured the radius stop-accounting-buffer memory-minor-threshold overwrite-oldest command. If you have configured this command, the device uses a new stop-accounting request to overwrite the oldest one. Otherwise, the device stops buffering new stop-accounting requests. After the link between the device and the server recovers, some users might fail to go offline in time.

Status control

ON

CLI: Use the snmp-agent trap enable radius accounting-cache-discard command.

OFF

CLI: Use the undo snmp-agent trap enable radius accounting-cache-discard command.

Recommended action

To resolve this issue:

1.Use the display memory-threshold command in any view to check whether the memory usage of the MPU reaches the minor memory alarm threshold:

  - If yes, go to step 2.

  - If no, go to step 5.

2.Check whether the configured minor memory alarm threshold is low:

  - If yes, use the memory-threshold command in system view to set the minor memory alarm threshold to a higher value as needed.

  - If no, go to step 3.

3.Use the radius stop-accounting-buffer cache command in system view to set the maximum number of stop-accounting requests allowed to a smaller value so as to reduce resource consumption caused by buffered RADIUS stop-accounting requests. Then go to step 4.

4.Use the test-aaa command in user view to test whether communication failures exist between the device and the RADIUS server:

  - If the test succeeds, it indicates that the RADIUS server is reachable. Go to step 5.

  - If the test fails, troubleshoot the link between the device and the server. If the issue persists when the link is normal, go to step 5.

5.Collect alarm information, log messages, and configuration data, and then contact H3C Support for help.
