Device Level Physical Topology Health
Use this topic to learn about
health of a device level physical topology.
If a topology is invalid, the device level physical topology health is degraded or else
healthy.
Device level physical topology validations for non-Clos fabric
- Ensure that two devices in rack must
have link between them.
- Ensure that each rack is connected to
at least another rack.
Device level physical topology validations for Clos fabric
- Leaf node must be connected to all
the Spine nodes.
- Spine node must be connected to all
the Leaf nodes.
- Border Leaf node must be connected to
all the Spine nodes or Superspine nodes but not both.
- Spine node must be connected to all
the Border Leaf nodes.
- No more than two Leaf nodes must not
be connected to each other.
- No more than two Border Leaf nodes
must not be connected to each other.
- Border leaf node and leaf node must
not be connected.
- Spine nodes must not be connected to
each other.
- Spine nodes must not be connected to
each other.
- Super Spine nodes must not be
connected to each other
- If a Leaf node is marked as "multi-homed", then the node must have a MCT
neighbor.
- If a Leaf node is marked as
"single-homed", then the node must not be connected to other Leaf node(s).
- If a Border Leaf node is marked as "multi-homed", then the node must have a MCT
neighbor.
- If a Border Leaf node is marked as
"single-homed", then the node must not be connected to other Border Leaf
node(s).
