Configuring a Global Discovery Blackout or Change Blackout

Scroll bookmark
bookmarkId Bookmark_Global_Blackouts

You can separately configure discovery blackouts and change blackouts. No dependencies exist between blackout types. You may configure either type without defining new settings for the other type. At the Global level, discovery blackouts and change blackouts apply across all network views, discovery ranges, device groups, and devices unless otherwise disabled at the range or device group level.

Complete the following:

1. Choose Settings icon –> Setup –> Collection and Groups.
2. On the Global page (which appears by default), check the Enable Discovery Blackout check box and click its Scheduling icon. The Discovery Blackout Scheduling gadgets appear.
   • In the Recurrence Pattern drop-down, choose how often you want to execute the blackout period. You can select Once, Daily, Weekly, or Monthly.
   • If you choose Once, complete the following:
     • Choose an Execution Time from the drop-down list.
     • Enter the date of the blackout, in the Day_of_ field.
     • Specify the Duration: 10 or more Minutes, Hours, or Days.
   • If you choose Daily, click either Every Day or Every Weekday.
     
     • Choose an Execution Time from the drop-down list.
     • Specify the Duration: 10 or more Minutes, Hours, or Days.
   • If you choose Weekly, complete the following:
     • Choose an Execution Time from the drop-down list.
     • Check the check boxes for one or more days from Sunday through Saturday.
     • Specify the Duration: 10 or more Minutes, Hours, or Days.
   • If you choose Monthly, complete the following:
     • Choose an Execution Time from the drop-down list.
     • Day __ of every __ month(s): Specify for the discovery blackout to be executed on day-of-month X of every Y month. Month numbering starts with January. You can see some examples below.
       Day 5 of every 1 month(s): means the blackout is executed on the 5th of the current and each next month.
       Day 5 of every 2 month(s): means the blackout is executed on the 5th of January, March, May, July, and so on.
     • Specify the Duration: 10 or more Minutes, Hours, or Days.
3. If necessary, select the Enable Change Blackout check box and click its Scheduling icon. The Discovery Blackout Scheduling gadgets appear. Follow the steps above to define the change blackout schedule.
4. Click Save to save your changes.

For discovery of any IPv6 network, at least one well-connected IPv6 router (preferably with routes to all other networks to be managed by NetMRI) must be placed in the Seed Router list. In some cases, seed routers may not have the full routing tables or be unable to provide full information for some reason. The general rule of thumb is that more seed routers are better, but the connectivity of the seed router(s) also helps determine how many seed routers you need. Avoid having more seed entries than necessary. Also, note that seed routers are included in the CIDRs count that should not exceed 1000 per the recommendation in the Infoblox Discovery Best Practices Guide.

NetMRI allows you to collect and manage data from SDN and SD-WAN environments. Currently, you can discover Cisco ACI and Cisco Meraki.

You can do the following in Settings icon –> To do so, go to Settings icon –> Setup –> Discovery Settings –> SDN. You can do the following on this tab:

• New: Add a new Cisco APIC or Cisco Meraki configuration. See Adding and Configuring Cisco ACI Discovery and Adding and Configuring Cisco Meraki Discovery.
• Edit: Modify information about a selected configuration.
• Delete: Remove a selected configuration from the list.
• Import: Import a CSV file containing Cisco ACI or Cisco Meraki information. For information about syntax formats, see Discovery Settings Import Formats.
• Show/Hide Credentials: Display or hide the user name and password credentials of added configurations.
• Discover Now: Start the discovery process immediately for a selected configuration.
• (For Operations Center only) Filter by Collector: Filter the added SDN configurations by Collectors that perform SDN discovery. Collector filter also displays respective device limits and licensing limits.

You can also define general SDN and SD-WAN settings as described in Configuring SDN and SD-WAN Polling Settings.

...

1. Make sure that you enabled SDN and SD-WAN polling in Settings icon –> Setup –> SDN/SD-WAN Polling. For more information, see Configuring SDN and SD-WAN Polling Settings.
2. Choose Settings icon –> Setup –> Discovery Settings –> SDN.
3. Click New.
4.  In SDN Type, select Cisco ACI.
5. Complete the following:
   
   • Fabric Name: Specify a short and unique name for the current Cisco ACI configuration.
   • Addresses: Click Add and enter the hostname or IP address of the Cisco APIC controller. If your fabric includes more than one controller, click Add again to add more addresses.
   • Network View: Select  Select the network view to identify the corresponding network interface for connectivity with the Cisco ACI. Also, this network view will be In parentheses next to the network view name is displayed the name of the associated collector. The network view and collector are assigned to discover devices from this the ACI fabric.
   • Protocol: Select HTTP or HTTPS.
     If you select HTTPS, you must use a Root CA or Intermediate CA certificate to allow communication with the Cisco APIC as described below. 
     If your ACI fabric includes multiple controllers, use a combined PEM certificate. To do so, copy the ASCII data from all of the certificates into a single file.
   • CA Certificate: Perform one of the following:
     • Select a previously imported CA certificate. To learn how to import a CA certificate in NetMRI, see Installing CA Certificate.
     • Click Import CA Certificate and select a CA certificate directly from your machine.
       For how to prepare a CA certificate, see About CA Certificates for Cisco APIC. The APIC controller address must match either the certificate subject or one of subject alternative names.
   • Username: The login name for the Cisco ACI.
   • Password: The login password.
   • Use Global Proxy Settings: Select if you want to use a Proxy server for connectivity to or from with the Cisco ACI. For more information, see Configuring Proxy Settings for SDN Discovery.
