Resource Limits/Feature Support

Limiting the resource usage or consumption (wherever applicable) helps to improve the system stability and also restricts over utilization of system capacity. In RBFS, the usage limits for the following resources are pre-defined:

  • IPv4 Route Count

  • IPv6 Route Count

  • NAT44 Rule Count

  • MTU Profile

  • L3 MTU-Profile

  • Subscriber MTU Profile

  • Physical MTU Profile

In addition, you can track the resource usage of the following features.

  • 6PE label

  • High Precision QoS

You can specify resource limits on the following images (also known as roles).
