Cisco Packet Data Serving Node Release 5.0 for Cisco IOS Release 12.4(22)XR
OL-19026-01
New Features in This Release
The conditions for notification are:
•
An AAA server state is notified as BUSY for round-trip time, no further traps or notifications are
sent to the NMS server for that particular AAA server until that server state becomes NORMAL for
the round-trip time.
sent to the NMS server for that particular AAA server until that server state becomes NORMAL for
the round-trip time.
•
After a retransmission BUSY trap is sent, no retransmission BUSY trap is sent to the same server
until the server state becomes retransmission NORMAL.
until the server state becomes retransmission NORMAL.
•
After an AAA server state is informed as NORMAL for round-trip time, no further round-trip time
NORMAL traps or notifications are sent to the NMS server unless the server state is identified as
BUSY for round-trip time.
NORMAL traps or notifications are sent to the NMS server unless the server state is identified as
BUSY for round-trip time.
•
After the retransmission NORMAL trap is sent, no retransmission NORMAL trap is sent to the same
server until the server state becomes retransmission BUSY.

To enable this feature, perform the following tasks:
Note
This feature is supported only on the Cisco SAMI card on the 7600.
The RADIUS-CLIENT-AUTHENTICATION-MIB is implemented per PDSN instance and each of these
instances generate a trap.
instances generate a trap.
The RADIUS-CLIENT-AUTHENTICATION-MIB contains entries for timeout on AAA access. A trap
is added based on this timeout occurring. It is also possible to set a threshold on round trip delay (defined
as a percentage of the maximum response time), and generate a trap when that threshold is exceeded. An
additional trap is generated when the round-trip delay falls below a second threshold. This provides a
level of delay for trap generation.

Step 1
Router(config)# radius-server snmp-trap

Enables you to generate SNMP traps that denote
AAA unresponsiveness.

normal is the normal threshold in percentage (that is,
50 to 75 normal value in percentage), used to
generate traps.

high is the high threshold in percentage (that is, 60 to
100 high value in percentage), used to generate traps.
100 high value in percentage), used to generate traps.
Step 2
Router(config)# radius-server snmp-trap
retrans-threshold
normal high
Generates a trap (SNMP notification) when
round-trip time or retransmit value exceeds the high
threshold value and falls below the normal threshold
value. The trap is generated for either round-trip time
or retransmit time.

Step 3
