1132.0. "weird behaviour of SNMP AM" by HERON::MORALES (DEC:.VBO.ACT.DECmcc|828-5383) Thu Jun 13 1991 08:03

	Hi,

We have a customer running DECmcc 1.1 and SNMP AM v1.0 (ssb) that has 
some problems with the SNMP AM  and alarms at high polling rates. (30 s).

I have reproduced a problem at the customer site and  on an internal
system running DECmcc 1.1 EFT and SNMP AM V1.0 (SSB).But couldn't
reproduce it with DECmcc V1.1 and SNMP AM X1.1

What is needed: 
	. an alarm running to check a counter of a reachable entity (uniriv)
	. a show snmp counters on a non reachable entity (anulsy)

This is the alarm rule running to show the strange behaviour of SNMP AM:

***********************************************************
Expression = (snmp uniriv sysuptime > 0, at every 0:0:30)
domain=ip-domain
***********************************************************
                     
and this running in batch:

*****************************************************************
$ manage/enter
enab domain ip-domain rule uniriv-sysuptime
notify domain ip-domain			(same behaviour without the notify)
show snmp anulsy all counters ,at every 0:0:10
****************************************************************

Here is the log of the batch: (LOOK at sysuptime values ).

*************************************************************
$ manage/enter

******************************************************************

I am currently working with a Customer Services support to try to
reproduce it on DECmcc V1.1 and SNMP AM V1.0

  Has someone tried this ??? or can someone try this and post his results .

	Thanks,

1132.1	Problem found - testing fix now...	CHRISB::BRIENEN	DECmcc Bridge\|Station\|SNMP Management.	`Tue Jun 18 1991 12:39`	13
	The problem documented in the base note (and in CLD#VBO-00640) has been found and the fix is being tested now. The fix will involve replacing the TCP/IP SNMP AM V1.0 executable with an updated one. The version number for the new executable (as shown by the command: SHOW MCC 0 TCPIP_AM ALL CHARACTERISTICS) is V1.0.1. Additional details supplied later... Chris
1132.2	New .EXE available.	CHRISB::BRIENEN	DECmcc Bridge\|Station\|SNMP Management.	`Tue Jun 18 1991 16:51`	11
	The updated TCP/IP SNMP AM V1.0 (with the "fix") is available in the following place: Directory MKNME::DUA1:[SNMP.KITS.V1_0.PATCHA] MCC_TCPIP_AM.EXE;3 173 18-JUN-1991 10:25:03.00 (RWED,RWED,RWED,R) Please note: This AM has been built/tested against DECmcc V1.1. It has not been tested (and probably will not work) on DECmcc V1.0. Chris
