Numbers of various negotiation packets:
You can use the above numbers to analyze
whether the transmission of data among fabric
units is normal, and thus to judge whether the
fabric operates normally.
Indexes of the left and right ports:
Number of units (both directly-connected and
subtending units) connected to the port,
including the device itself.

Heart Beat: Heat beat packet, which is used
to advertise topology connections to the units
by the FTM-Master after convergence.
Left Check: Handshake packets between
neighbors. They are sent from the left port
and used to monitor the state of the
neighbors periodically.
Right Check: Handshake packets between
neighbors. They are sent from the right port
and used to monitor the state of the
neighbors periodically.
Auto update: Number of auto update packets
sent and received
IsEdge: Whether the device is at either end of
a bus topology XRN fabric in which the
number of member devices has reached the
upper limit.
0: No
1: Yes
1: The left port has no connected unit
2: The right port connects to one unit
