Timestamp per IEEE802.1AS. It is advertised with prefix
to achieve mobility.
level
uint8
The value of node level.
Clos and Fat Tree networks are topologically partially
ordered graphs and 'level' denotes the set of nodes at
the same height in such a network.
Nodes at the top level (i.e., ToF) are at the level with
the highest value and count down to the nodes
at the bottom level (i.e., leaf) with the lowest value.
In RIFT, level 0 always indicates that a node is a leaf,
but does not have to be level 0.
Level values can be configured manually or automatically
derived.
system-id
string
This type defines the pattern for RIFT System IDs.
An example of a System ID is 0021.2FFF.FEB5.6E10.
