Device serial number not discover

[Balakrishnan Kuppuswami]

hi

Our Device is reachable and also able to discover device Mac through MiB in CA but not able to get only serial number.

For that we have to manually fetch device serial number and need to add.

In free software ( Mib browser we can get both serial number and Mac ) but not in CA.

Please guide how to get serial number while discovering device.

Thnx.

Hi,

Thanks for your reply, In our CA Spectrum we are using SNMP Version 2 , so will your reply will work with same procedure in SNMP V2?

[Silvio Okamoto]

Yes. SNMPv1 uses 32 bits counters and SNMPv2c and SNMPv3 use 64 bits counters.
So for Serial Number, no matter if you are using SNMP v1, v2c, or v3.

Hi Silvio,

There are more than 1000 switches installed at Different location and as per your replied we have to manually fetch each switch serial number and it's time consuming.

Is there any other way to discover serial number ( i.e. by changing in MiB ) in CA ?.

Here with we are attaching our MiB file,  Request you to please guide if any changes required in MiB so we can get Serial Number automatically.

Thanks

Hi Balakrishnan,

The Attribute Editor can make this change in bulk - you do not have to do this individually.  Please see the end of the instructions from the KB:

Thanks!

Hi Brian,

In our all switches we got 0xfff00005 attribute ID, can we set this Attribute in CA Software permanently for getting switch serial number automatically ?

Right Now every time we have to fetch serial number via 0xfff00005 attribute ID manually.

Also confirm our attached MiB file is OK or need to change anything ? 

Please guide. 

[Brian_Jackson]

Hi Balakrishnan,

If the MIB is mapped to attribute 0xfff00005 in MIB Tools, you can use the attribute editor (Tools->Utilities->Attribute Editor) to make this persistent across all of your devices.  If the MIB imported into MIB Tools and compiled successfully, then there is no need to do anything else with the MIB.

Attribute Editor Documentation: https://techdocs.broadcom.com/content/broadcom/techdocs/us/en/ca-enterprise-software/it-operations-management/spectrum/10-4-1/managing-network/modeling-and-managing-your-it-infrastructure/oneclick-attribute-editor.html

Let us know how it goes!

Thanks,

Brian

Hi Brian,

Thank you for your reply.

can you please provide us Demo link of CA for 10 days ? we can check from our side and confirm with Client.

Awaiting your reply.

Hi Brian,

I search in Youtube and found below link:

https://youtu.be/DGchBbS-Zbw

Can you please help us how to certified Our Plexonics Device with Broadcom CA?

After certified our Device will you set any patches will help to get serial number automatically. ( Not required to used as per your all above answer ).

Normally in Cisco Device while we discover device , under asset information all details will show. but in our Case we cannot.

In our case we are also going to install same switches in same Network so every time we have to use above activity.

In same network other Vendor Devices also installed. so request you to please share us permanent solution. Because every time we will not fetch serial number manually.

Thanks

[Brian_Jackson]

Hi Balakrishnan -

Once you've made a change in the Model Type Editor (MTE) the change is permanent; any time a new device of that type is added to Spectrum it will have the supported attributes.

If you're running into issues I'd suggest opening a ticket with the support team to help walk you through the process.  If there are particular devices where you've made the serial number change you can also open a ticket asking for the out-of-box certification to either be created or modified to support that change.

BR,

Brian

Hi Brian

First we are not gettingNgetting serial number so as per your team guidance we are manually fetch the serial number but now  we are not getting Mac address of device once getting serial number. Our client already raise ticket for the same  ticket ID :- 31820599 & 20148679.

Request you to please guide for the same.
We are as oem can we raise ticket for this issue? But we do not have broadcom id.

[Balakrishnan Kuppuswami]

Hi Brian

Previous we are not getting serial number issue, so as per your team guidance we are manually fetch the serial number but now  we are not getting Mac address of device once getting serial number. Our client already raise ticket for device serial number not discover in CA against ticket ID :- 31820599 & 20148679.

Right now once we discover the device we got only MAC address but after change Attribute ID and re-discover we got only serial number.

Request you to please guide for the same.
As being OEM can we raise ticket for this issue? 

here with we attached both deivce snmp Walk in which 10.47.37.4 getting only Serial Number and 10.47.37.5 get SN and MAC both.

Awaiting your reply

Hi -

I'm not sure that I understand.  If you imported the correct MIB for the device and then mapped the serial number OID to an attribute, it would not have over-written any other attributes.  Once you have the new attribute from MIB tools, you are telling Spectrum which attribute to look at to display the serial number.

MIB (from vendor) --> OID for Serial Number --> attribute in Spectrum DB

Once the attribute is mapped in the Spectrum DB, you can apply that to a single device or to multiple devices.  You do this with the Attribute Editor.  As long as you have selected the correct attribute ID and attribute (serial number) to map to each other, all of the devices will show the serial number.

If you are still having issues, or if you've accidentally over-written something, then I would suggest to continue working with support, who will be able to provide step-by-step instructions and / or a remote-session to resolve the issue.

BR,

Brian

Hi Brian
Can you confirm your schedule time for remote session? I will check with client and confirm it. Please try to schedule it on Wednesday after 2:00PM IST.

Regards.

[Brian_Jackson]

Hi -

You'll need to work with the Support team for a remote session; I would suggest asking for one in the tickets that you currently have open.

BR,

Brian

Hi, Silvio,

As our client is Government so we are not allow to testing revised MiB, Request you to please share us CA Demo Link so we can test our Revised MiB at our end.

Thanks.

[Balakrishnan Kuppuswami]

Hi Silvio/ Brian,

We have tested auto discovery on one location and have following observations :

10.83.103.96  - PL-2418MG-16 P ( Switch IP )

10.83.103.92  - PL-2426MG-24PL ( Switch IP )

NMS Server IP :- 172.18.101.171       

 10.83.103.97 – Laptop IP
--------------

1. The NMS is Using Wrong OID or MIB file to discover Plexonics Switch, That's why the Switch unable to send correct response back to NMS server ( refer the attached snapshots captured from wireshark which clearly explains the issue)
1. we believe that our MIB File is not properly updated or recognized by CA Spectrum for which we need to your support to update
2. we also believe this can be solved if NMS software can discover the switch using IP address and OID together
2. NMS server also send  SNMP v1 request even though it was configured as v2c in both NMS software and Switch 
3. We tested with PRTG NMS software on that we can abel to get correct OID and SNMP Version discovery 

Refer all the Snap shot details attached

Awaiting your reply..

[Balakrishnan Kuppuswami]

Hi Team,

Awaiting your reply..

[Jason Volpini]

Hello Balakrishnan

I followed the information on this thread and I believe you have been given the proper information to move forward with this. However I will clarify a few points. 

#1. new vendor devices may have MIB details which Spectrum is not yet aware​.
#2. in cases where certain MIB objects (especially custom mapped MIB objects with codes starting with "0xfff") Spectrum may not be able to poll custom MIBs until they are properly defined in the database for that device model type.

This is the issue that you are facing. You are using a device which Spectrum is not aware, and have a custom mapped MIB object 0xfff00005 

You can check if a Device is Certified within Spectrum at this link: https://ehealth-spectrum.broadcom.com/devices/html/search_sp.html
I checked your OID based on the WALK you provided, and 1.3.6.1.4.1.49281 is -not- a Certified device - meaning any non-certified Devices may show unexpected behavior due to Spectrum is not aware of this device until Certified.

​​From here, you have two options: 

option A: Self-Certify the device using Model Type Editor - note - MTE is an ADVANCED feature of Spectrum and should only be used with CARE and after understanding the documentation on it. Changes in MTE are permanent changes to the Spectrum device catalog and using this feature should only be done by experienced Spectrum users. That said, MTE is very powerful and can allow self-Certification of devices, such as mapping custom Attributes.

For Self-Certification, here is a KB with much information and links to helpful docs on Self-Certification, as well as helpful You-Tube videos: 

https://ca-broadcomcsm.wolkenservicedesk.com/wolken/esd/knowledgebase_search?articleId=129149

option B: Open a support case, and provide SNMP WALK so that the device can be submitted to official Certification by Spectrum engineers. The device would be available in a future version of Spectrum or Certification Pak , so be sure you have the most current version of Spectrum running

So from here, you have the options to Self-Certify the Device, or to open a Support case to submit the Device for Certification. if you have any questions on Self-Certification, we would recommend a support case. Thus in any event, if you have further questions on this which is not solved by checking suppor.broadcom.com, or by checking the KBs which have been provided to you, then a Support case would be your next step.

Hi,

Thanks for your reply.. we will inform our client to do same. 

Our Client already re-open Support ticket and got reply from CA team to arrange remote, they will arrange remote to do above your reply activity.

One more thing in Device Type we got SNMPBG,RealteK Semiconductor corp. details , so can we set Device Type as our Switch Model Number.

In our MiB file we create OiD for Model Number.

Kindly find attached Image for your reference.

[Joseph Ackley]

You can change the device type by doing either of the following:

1. Select the model, click on the attributes tab, search and select the DeviceType attribute and manually change the value

2.Use the Device Certification tool to change the Device Type for the sysObjectID for that device. 

Joe

[Balakrishnan Kuppuswami]

Hi,

We tried as per your above step we got our Switch model Number in Device Type section, but still not getting Serial Number.

Client already raised official ticket at support and from your side required MiB file, SNMP OiD and SNMP walk details.

Here with we also attached our Switches MiB files and SNMP walk and SNMP OiD details for your reference.

Please look into this and provide solution.

Regards.
