Inventory change not recognized

Hi all,

We have the following cisco voice device:


Platform Type 7835I2

Processor Speed 2333

CPU Type Intel(R) Xeon(R) CPU 5140 @ 2.33GHz

Memory 2048 Mbytes

Object ID 1.3.6.1.4.1.9.1.585

OS Version operatingsystem.UCOS3.0.0.0-42


which is added for management in the LMS 3.0 application. Recently, the device was updated with additional 2 GB of memory, but this change was not reflected in DFM and RME applications. I have started inventory job, but it states that the device has only 2048 MB of memory installed. On other side, the Call Manager application on the device recognizes the change and it states that has 4096 MB of memory.

I used a protocol analyzer to catch the snmp communication between LMS and Call manager. Here it is the Call Manager snmp response:

SNMPv2-MIB::sysDescr.0 (1.3.6.1.2.1.1.1.0): Hardware:7835I2, 1 Intel(R) Xeon(R) CPU 5140 @ 2.33GHz, 2048 MB Memory: Software:UCOS 3.0.0.0-42


Any ideas why this is happening?

Velin,


The following:


SNMPv2-MIB::sysDescr.0 (1.3.6.1.2.1.1.1.0): Hardware:7835I2, 1 Intel(R) Xeon(R) CPU 5140 @ 2.33GHz, 2048 MB Memory: Software:UCOS 3.0.0.0-42


Is what you captured ?


Regards,

Omar

Yes, that is what i captured with the protocol analyzer. But actually the server has 4 GB memory.

You means that this is not LMS problem but it the server's because it's not announcing the correct RAM size.

Are you verified that the server is using effectively 4GB of RAM ??

Yes, i think maybe it is not a LMS problem, because for some reason the server is not announcing (through SNMP) the correct RAM size installed. On the other side, the Call Manager application that resides on the server shows that the RAM size is 4 GB

You tried to reload the server ? or the SNMP agent service?

Yes, i tried to reload the Call Manager server, but nothing changed.

This is what i see, when snifferring DFM and Call Manager snmp communication:


RFC1213-MIB::mib-2.25.3.3.1.2.1 (1.3.6.1.2.1.25.3.3.1.2.1): 12

RFC1213-MIB::mib-2.25.3.3.1.2.2 (1.3.6.1.2.1.25.3.3.1.2.2): 13

RFC1213-MIB::mib-2.25.2.3.1.5.2 (1.3.6.1.2.1.25.2.3.1.5.2): 512062 (hrStorageSize)

RFC1213-MIB::mib-2.25.2.3.1.6.2 (1.3.6.1.2.1.25.2.3.1.6.2): 0 (hrStorageUsed)

RFC1213-MIB::mib-2.25.2.3.1.6.1 (1.3.6.1.2.1.25.2.3.1.6.1): 1017417 (hrStorageUsed)



And here are the results from a snmp walk on the Call Manager. Here i can see the correct amount of memory installed:


SNMP Walk Output .1.3.6.1.2.1.25.2.2


HOST-RESOURCES-MIB::hrMemorySize.0 = INTEGER: 4087680 KBytes


And these a re the results from snmp walk on the mibs .1.3.6.1.2.1.25.2.3.1.6 (hrStorageUsed)

and .1.3.6.1.2.1.25.2.3.1.5 (hrStorageSize)


SNMP Walk Output .1.3.6.1.2.1.25.2.3.1.6


HOST-RESOURCES-MIB::hrStorageUsed.1 = INTEGER: 1016584

HOST-RESOURCES-MIB::hrStorageUsed.2 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageUsed.3 = INTEGER: 2830576

HOST-RESOURCES-MIB::hrStorageUsed.4 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageUsed.5 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageUsed.6 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageUsed.7 = INTEGER: 8420542

HOST-RESOURCES-MIB::hrStorageUsed.8 = INTEGER: 8413

HOST-RESOURCES-MIB::hrStorageUsed.9 = INTEGER: 8207

HOST-RESOURCES-MIB::hrStorageUsed.10 = INTEGER: 11353



SNMP Walk Output .1.3.6.1.2.1.25.2.3.1.5


HOST-RESOURCES-MIB::hrStorageSize.1 = INTEGER: 1021920

HOST-RESOURCES-MIB::hrStorageSize.2 = INTEGER: 512062

HOST-RESOURCES-MIB::hrStorageSize.3 = INTEGER: 3111096

HOST-RESOURCES-MIB::hrStorageSize.4 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageSize.5 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageSize.6 = INTEGER: 0

HOST-RESOURCES-MIB::hrStorageSize.7 = INTEGER: 10817708

HOST-RESOURCES-MIB::hrStorageSize.8 = INTEGER: 256665

HOST-RESOURCES-MIB::hrStorageSize.9 = INTEGER: 3111104

HOST-RESOURCES-MIB::hrStorageSize.10 = INTEGER: 510960


What i understand is that maybe DFM does not request all the available mib information from Call Manager, regarding the memory state.


I really appreciate any help on this, cause it's getting on my nerves now :)
