Bug ID: 255558
Summary: No IPv4/ARP traffic on vlan interface when using
IntX.Y notation, vlanXY works
Product: Base System
Version: 12.2-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: bugs at FreeBSD.org
Reporter: c+freebsd at dahoffmann.de
Hi,
when using 'ifconfig bge0.60 create' / 'ifconfig bge0.60 vlan 60 vlandev bge0
up', i only see ARP and ipv6 traffic on the interface, but no IPv4 nor DHCP
replies. Verified by using tcpdump on the parent and the vlan interface,
switchport config Untagged/Tagged(60)
using tagged only on bge1, there is the same behavior:
ifconfig bge1 up
ifconfig bge1.10 create vlan 10 vlandev bge1 up
ifconfig bge1.60 create vlan 60 vlandev bge1 up
bge1.10 -> everything ok, dhcp&ipv4 flows in and out
bge1.60 -> only arp&ipv6 traffic show up in tcpdump
After using 'ifconfig vlan60 create / 'ifconfig vlan60 vlan 60 vlandev bge0
up', the whole traffic passes the interfaces, still using bge1.10 for vlanid
10.
System:
12.2-RELEASE-p6 FreeBSD 12.2-RELEASE-p6 GENERIC amd64
best regards
Daniel
