Hi,


I'm running IPM 4.2.0 (LMS 3.2) on Solaris.

I configured a new operation called 'NEWPING'. The operation's configuration is attached.

Basiclly, it suppose to ping a target and whenever there is a timeout of 2 consecutive pings then raise a threshold and alert (via trap).

I noticed that as soon as the first timeout occures, the source is sending a trap without waiting for the second ping to timeout (as per the operation definition).


My source router is running Cisco Catalyst 6509 Switch with IOS (tm) s72033_rp Software (s72033_rp-IPSERVICESK9-M), Version 12.2(18)SXF13, RELEASE SOFTWARE (fc1).


This is how it is configured on the device:

Entry Number: 190512
Owner: ipm|owner
Tag: L65A_AMIT
Type of Operation to Perform: echo
Reaction and History Threshold (milliseconds): 5000
Operation Frequency (seconds): 60
Operation Timeout (milliseconds): 5000
Verify Data: FALSE
Status of Entry (SNMP RowStatus): active

Target Address: <ip address>
Source Address: 0.0.0.0
Target Port: 0

Connection Loss Reaction Enabled: FALSE
Timeout Reaction Enabled: TRUE
Threshold Reaction Type: consecutive
Threshold Falling (milliseconds): 3000
Threshold Count: 2
Threshold Count2: 5
Reaction Type: trapOnly
Verify Error Reaction Enabled: FALSE
Number of Statistic Hours kept: 2
Number of Statistic Paths kept: 1
Number of Statistic Hops kept: 1
Number of Statistic Distribution Buckets kept: 1
Statistic Distribution Interval (milliseconds): 20
Number of History Lives kept: 0
Number of History Buckets kept: 15
Number of History Samples kept: 1
History Filter Type: none


I noticed the same operation works just fine using a different source:

Cisco Catalyst 4506 Switch running Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500-ENTSERVICESK9-M), Version 12.2(52)SG, RELEASE SOFTWARE (fc1)


Did anyone know why it is not working properly on the 6509? Is there a workaournd or way to make this work?


Thanks,

Amit

This sounds like CSCsx56252.  Essentially, the consecutive keyword was a no-op in earlier versions of code.  Newer versions of 6500 code which support the "ip sla" command set should work.
