2.16 MD8000 Multimedia Transport System MD8000 Rev. H
The Trunk to Trunk connection allows a ring network configuration composed of multiple
MD8000 units. Under such a configuration, you
must not make a communication path loop in
order for normal network operation and management. If 10gEther-7 in Slot 24 of Chassis C
has a network connection with a supervisory terminal as shown in Figure 2-10, and if the
parameters are set as shown in Table 2-6, then the Inband communication packets indefinitely
circulate in the loop disrupting normal network operation.
