Cisco UCCE SNMP and Diagnostic Framework Web Credentials Settings

Looking for some clarification on how to properly update the both the SNMP v2 string/v3 credenitials and Diagnostic Framework Web credentials for a Cisco UCCE instance on version 11.9.  I'm aware that 11.9 allows for these to be configured individually for each device in the instance, unlike previous Prognosis version wheres all devices had to use what was configured under the instance itself.  I have a scenario where I need to update the Diagnostic Framework credentials for an existing UCCE instance.  If I update the credentials under the instance itself, will that automatically filter down to all devices within the instance as needed or do I need to actually update the credentials under each of the 100+ devices in the instance?  I tried experimenting via both the WebUI Admin and Windows Client password config, but had mixed results... so looking to confirm the correct method.

 

Thanks

Re: Cisco UCCE SNMP and Diagnostic Framework Web Credentials Settings

Are there any know Prognosis bugs in 11.9 (patch 5) regarding Cisco UCCE and password configuration file issues?

Re: Cisco UCCE SNMP and Diagnostic Framework Web Credentials Settings

Hello @Timon_Dennis ,

 

In Prognosis Platform 11.9, patches 4 & 5 changed the way credentials for servers in a UCCE cluster are handled.

 

Formerly, a single credential for all servers in a UCCE cluster was the only option.
The updates in the patches added the ability to use per server credentials for a UCCE cluster.
There are still hooks in the UCCE collector to use cluster wide credentials, but there could be some interactions with the updates.

 

Support would need several specifics to know how best to answer this question. Please open a Support case including the irfax from the Managing and Monitoring Nodes so this item can be reviewed and an environment specific answer can be provided.

 

Thank you,

Scott Baldwin

Re: Cisco UCCE SNMP and Diagnostic Framework Web Credentials Settings

Thanks for the info Scott.  We are currently running 11.9 patch 5.  Looks like the associated UCCE credential changes introduced with either patch 4 or 5 have resulted in a defect.  Below is what I encountered.

 

We have multiple pre-existing UCCE instances.  As with previous Prognosis versions, each UCCE instance has one set of credentials used by all devices that are added via the first device add.  This set of credentials is reflected by a single entry in the password configuration listed under the instance name.  I recently added a new UCCE instance to Prognosis via the WebUI.  Per the changes introduced in patch 4 and 5, the credentials had to be entered for each device within the instance.  This resulted in an entry being inserted into the password configuration for each new UCCE device added.

 

Once I added the new instance and all associated devices, I noticed Prognosis lost contact to all my pre-existing UCCE instances (minus the device that was used to create the instance which is when the single credentials were previously added).  What I found was that when I added the new UCCE instance, Prognosis also automatically added new entries for every single device in all the pre-existing instances.  These newly added entries were obviously added default credentials that did not match was used to create those original instances, thus why Prognosis lost contact to all those pre-existing UCCE devices.

 

I have since tested and replicated this issue multiple times in our lower environments.  What I found is that on our 11.9 patch 5 version, the first time a UCCE device change is made that touches the password configuration, Prognosis automatically adds a default credential entry for every pre-existing UCCE devices.  This can be triggered by adding a new instance, adding a device to an existing instance or simply making a change to the credentials of an existing device.

If the individual UCCE device entries are deleted from the password configuration, the device resorts back to using the original correct credentials configured under the instance entry and thus becomes contactable again.  That is only a temporary fix as all individual device entries are re-inserted to the password configuration the next time a UCCE update is made.  It looks like the correct fix is to manually update each of the newly added default device entries in the password configuration with the correct credentials for all pre-existing UCCE devices.  Once done, the pre-existing UCCE devices become contactable again.

 

I am happy to open a support case to provide details of the finding along with any supporting logs, files, etc. as this is something that probably needs to be addressed in a future patch.  Others should be aware of this as well though, as I learned the hard way on our production system.

Re: Cisco UCCE SNMP and Diagnostic Framework Web Credentials Settings

Hello @Timon_Dennis,

 

Thank you for all the wonderful information about this UCCE password issue in Prognosis.
There are a few customers seeing this issue now in Prognosis Platform 11.9 patches 4 & 5.

 

I'm in the process of escalating this "additional UCCE password entries" to IR Development. Sharing with Development the number of customers seeing this issue will help Development understand the impact and add weight to the escalation.

 

Please go ahead and open a case including:

  • An irfax from the Managing and Monitoring Nodes.
  • Add my name to the case notes so I can make sure to add the case to the escalation.

I will also add all the great information from this thread to the case notes as well.

 

Thank you,
Scott Baldwin

Re: Cisco UCCE SNMP and Diagnostic Framework Web Credentials Settings

Hi Scott,

I have logged case 52397 with support so it can be further investigate and escalated to development as needed  The support case contains an overview of the issue along support IRFAX's and password configuration files I captured along the way while reproducing the the issue.

 

Thanks!

Tim

Hi @Timon_Dennis,

 

Thank you for opening case case 52397!

 

I will be contacting IR Development with the information you found and included in the case along with additional information from Support.

 

We will use the case to continue communication directly with you for this issue.

 

Thank you,
Scott Baldwin
