Unorganized :)
>Environment:
A regular FreeBSD 4.2-stable machine, with 2 3com xl cards on a cisco
catalyst with a trunc port.
>Description:
My machine reboots if I configure an IP number on a vlan, which vlandevice
is not configured with an ip number.
Eg:
# ifconfig xl0
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 00:01:02:11:ad:e4
media: autoselect (100baseTX <full-duplex>) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
# ifconfig vlan0 vlan 120 vlandev xl0
# ifconfig vlan0 10.10.10.2 netmask 255.255.255.0
<instant reboot>
If I run the ifconfig command on the vlan interface with ip numbers, it
will reboot the machine. It doesn't care if I combine the vlan defenition
and the ip address config, it will crash the machine as well.
>How-To-Repeat:
See above.
>Fix:
If you put an IP number on the vlandevice, it will work.
