Fabric Level Physical Topology Health
The fabric level physical topology
health is calculated based on the fabric level errors of the topology.
The Physical topology health is divided into two parts:
- Fabric level physical topology
health: It is used to calculate a fabric health.
- Device level physical topology
health: It is used to calculate a device operational state health.
Fabric Level Physical Topology
Validations for non-Clos Fabric
- Ensure that each rack must have two devices.
Non-Clos Fabric Level Topology Error Scenarios
- Only one device is present in the rack
Fabric Level Physical Topology Validations for Clos Fabric
- Ensure that the stage 3 fabric
contains at least one leaf or border leaf and spine device.
- Ensure that the stage 5 fabric
contains at least one leaf or border leaf and super-spine devices
Clos Fabric Level Topology Error Scenarios
- For 3-stage Clos fabric:
- No leaf or border leaf
devices in fabric
- No spine devices in the
fabric
- For 5-stage Clos fabric:
- No leaf or border leaf
devices in fabric
- No Super-spine devices in
the fabric
If the topology is invalid, the fabric level physical topology health gets degraded
or else it is healthy.
