Network interface not come up automatically after disconnection / connection of the network cable

[ebalcsk]

Hello,

 

I am using a orangepi one plus, but that might be no connection with my issue.

 

I am having the following network configuration:

# Network is managed by Network manager
auto lo
iface lo inet loopback


allow-hotplug eth0 eth0.1 eth0.10

auto eth0
iface eth0 inet manual
  pre-up ifconfig $IFACE up
  post-down ifconfig $IFACE down

auto eth0.1
iface eth0.1 inet static
  address 192.168.1.250
  netmask 255.255.255.0
  gateway 192.168.1.1

auto eth0.10
iface eth0.10 inet static
  address 192.168.10.1
  netmask 255.255.255.0

if i disconnect the network cable and connect back the interface is not come up automatically

from the state it is loks like up (docker interfaces are omitted):

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 02:07:e8:23:49:f2  txqueuelen 1000  (Ethernet)

but cannot ping

 

if i restart the interfaces connection is restored

ifdown eth0.10
ifdown eth0.1
ifdown eth0
ifup eth0
ifup eth0.1
ifup eth0.10

interface output looks the same:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

I wonder what is the problem?

Thank you
