Recommendations

The following list of recommendations summarizes those recommendations covered throughout this document:

• Check how you connect the WAN router to the EX Series Switch and what features it supports. When using a LAG between the two devices, features like active LACP and “force-up” will help you manage the attached EX Series Switch more effectively using in-band management.
• Use switch templates for efficient configuration management. Configuration errors and unnecessary additional work can be avoided this way.
  • Use the template hierarchy from organization-level templates to site-level templates. Making changes to individual switches should be done as a last resort.
  • Rather than making changing to individual switches, leverage the use of site variables for unique configuration settings within templates.
  • Do not duplicate templates to make unique configuration settings. Having many templates may cause you to lose sight over time. Leverage features like site variables and roles instead.
• Juniper recommends enabling the protection of the Routing Engine .
• When needing to decide how to manage port configuration dynamically:
  • Assigning VLANs and filters via RADIUS/NAC infrastructure is the recommended approach. Especially for those customers using Juniper Mist Access Assurance.
  • Using Dynamic Port Configuration is less preferred.
• When using Dynamic Port Configuration:
  • Avoid a high number of port flaps for a DPC-configured port.
  • Refer switch insights to ascertain the individual configuration is applied.
• Try to avoid using additional Junos CLI commands if possible.
