How to manually register Stacked Switches in CMDB

[Martina M]

Hi there,

Could you please navigate me an help me what is the best practise for Stacked switches registration? When we have one master switch and several slave switches? We do not use Discovery on Network devices and we do the registration manually. Currently we have it as one CI with multiple Serial Numbers which represents master and slave switches. Does any Class exist where we can mark it as Stack and  master and slave? And also what kind of relation would you use between them?

Thanks a lot!

@Christopher Smith are you in a position to share your Juniper Stacked Switch pattern so that others can learn from your experiences?
I have another customer who is about to head down the path of creating another stack switch pattern based on the OOTB pattern.
Thanks.

@Dean Hayes Will do.  Let me put my thoughts together on this and write out the steps within the next day or two.

Ok @Dean Hayes let's see if I can map out the steps.  First, I'd like to say the network switch pattern seems astronomically and needlessly complicated like a handful of different developers over the years put their own spin on pulling the same values multiple times as well as being very Cisco focused, but it is what it is 🙂

1. I took the Stacked Switches pattern library and duplicated it, changed the id to its own sys_id in the pattern tab, line 3.
2. I took the OOTB Network Switch pattern and copied it with the steps.
3. I swapped out the OOTB switches library added in step 39 with the custom one I made in step 1.
4. Step 39.2 switched entPhysicalClass condition to equals 5 instead of 3.
5. Step 39.3 same thing, swap the 3 for a 5.  I think that's about it for the patterns.
6. There are two pre post processing scripts you copy:  
1. Delete Switch Stack stale old master relations.  In pattern field, add your new copied pattern from step 2.
2. IP-Switch Switch Stack. In pattern field, add your new copied pattern from step 2.
7. Copy the Standard Network Switch SNMP Classification
1. Make sure the classification criteria are there in the related list. Should be two for printing and switching.  If they are missing, just create two: printing = false, switching = true.
2. Add a 3rd criteria: sysdescr contains Juniper.
3. There should be 1 SNMP OID Classification in the related list tab to create: 1.3.6.1.4.1.2636.1.1.1.2.63. Table is IP Switch and the Classifier is the one you created in this step.
4. Triggers probe related list on this SNMP Classification is name: HorizontalDiscoveryProbe-Horizontal Patt; probe: Horizontal Pattern; phase is identification; active is true; and pattern is the one you created in step 2 above.
8. In navigator filter, go to sa_pattern.list.  Open the OOTB pattern and the copy you made in step 2.  Make sure the Related CI Types match.  There might not be any in the copy pattern you made.  I can't remember

I think that should be it.  Hit me up if I missed something.

Thanks @Christopher Smith .  I appreciate the time and information.
