I don't know why the VC ports are showing Abesent in the second switch. DAC cable is connected to the QSPF port in the switch.
First switch:
user@EX4300-2> show virtual-chassis vc-port fpc0: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port 1/0 Configured -1 Down 40000 1/1 Configured -1 Down 40000 1/2 Configured Absent 1/3 Configured Absent {master:0} --------------------------------------------
Seconds switch: user@EX4300-2> show virtual-chassis vc-port fpc1: -------------------------------------------------------------------------- Interface Type Trunk Status Speed Neighbor or ID (mbps) ID Interface PIC / Port1/0 Configured Absent 1/2 Configured Absent 1/1 Configured Absent {linecard:1} user@EX4300-2>
