[j-nsp] VCP-ports with missing neighbors on QFX

[Franz Georg Koehler]

After some research, this seems to be a bug (BTW, this is on: 14.1X53-D30.3)
We see a lot of those messages:

fpc4 dcbcm_check_stuck_buffers: Buffers are stuck on queue 0 of port 69 
fpc4 Soft reset port 69 due to stuck buf 
fpc4 MacDrainTimeOut:port 0,hg1, timeout draining packets (131068 cells remain) 
fpc4 : dcbcm_drv_port_get_link_status : MmuDrain fail for port 69 : reason Internal error 
fpc4 MacDrainTimeOut:port 0,hg1, timeout draining packets (131068 cells remain) 
fpc4 : dcbcm_drv_port_get_link_status : Port disable fail for port 69 : reason Internal error

fpc6 dcbcm_check_stuck_buffers: Buffers are stuck on queue 7 of port 69 
fpc6 Soft reset port 69 due to stuck buf 
fpc6 MacDrainTimeOut:port 0,hg1, timeout draining packets (131070 cells remain) 
fpc6 : dcbcm_drv_port_get_link_status : MmuDrain fail for port 69 : reason Internal error 
fpc6 MacDrainTimeOut:port 0,hg1, timeout draining packets (131070 cells remain) 

Port 69/hg1 seems to be the VCP-Port that is not operational any more:
TFXPC3(vty)# set dc bc "phy info"

HW (unit 0)

Does anybody have an idea besides complete reboot (and upgrading the software at that chance)?
