Channelizing Interfaces
CAUTION: Starting with Junos OS Release 18.1R1, default behaviors changed
for:
•
System mode–Flexi-pic mode is replaced by non-oversubscribed mode.
The Flexible PIC Concentrator (FPC) no longer reboots when the system
mode changes.
•
Auto-sense–-The ports auto-sense the transceiver and set the port speed
to match.
