Hi all,
Same problem here.
One tagged VLAN (6) and untagged VLAN. After every reboot the untagged VLAN doesn't work until I disable and re-enable the Untagged VLAN virtual adapter. The VLAN6 doesn't present this problem and can ping other hosts in the same VLAN.
NIC is connected to a Cisco switch with the following config:
nwcore2#sh run | s 2/0/39
interface GigabitEthernet2/0/39
description AURELIO (0B39D)
switchport trunk allowed vlan 1,6
switchport mode trunk
spanning-tree portfast trunk
spanning-tree bpduguard enable
Let me know if you need any information to try to detect the issue. As ziesemer I have no dump as the system doesn't crash.
Best regards
Aurelio Llorente
