>Description:
I want to create, at boot time, a bridge with a fixed IP address (doesn't
change anything if I try DHCP) and a fixed MAC address (as I have an arp
watcher running on my network).
If I try to do that manually, it works:
shagshag# ifconfig bridge0 create
bridge0: Ethernet address: 8a:55:e7:96:89:b8
shagshag# ifconfig bridge0 ether 00:00:24:c8:e2:28
shagshag# ifconfig bridge0 addm vr0 addm vr1
shagshag# ifconfig bridge0 inet 192.168.1.201/24
shagshag# ifconfig bridge0
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 00:00:24:c8:e2:28
inet 192.168.1.201 netmask 0xffffff00 broadcast 192.168.1.255
id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
maxage 20 holdcnt 6 proto rstp maxaddr 100 timeout 1200
root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
member: vr1 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
member: vr0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
shagshag#
But if I want to do it on one single configuration line (what is done
at boot time), I have:
shagshag# ifconfig bridge0 destroy
shagshag# ifconfig bridge0 create
bridge0: Ethernet address: 4a:b5:68:28:39:92
shagshag# ifconfig bridge0 ether 00:00:24:c8:e2:28 addm vr0 addm vr1 inet 192.168.1.201/24
ifconfig: can't set link-level netmask or broadcast
shagshag#
So I tried various things:
shagshag# ifconfig bridge0 destroy
shagshag# ifconfig bridge0 create
bridge0: Ethernet address: 76:8c:99:38:74:5f
shagshag# ifconfig bridge0 ether 00:00:24:c8:e2:28 addm vr0 addm vr1
shagshag# ifconfig bridge0 inet 192.168.1.201/24
shagshag# ifconfig bridge0
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 00:00:24:c8:e2:28
inet 192.168.1.201 netmask 0xffffff00 broadcast 192.168.1.255
id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
maxage 20 holdcnt 6 proto rstp maxaddr 100 timeout 1200
root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
member: vr1 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
member: vr0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
shagshag#
But:
shagshag# ifconfig bridge0 destroy
shagshag# ifconfig bridge0 create
bridge0: Ethernet address: 4a:b5:68:28:39:92
shagshag# ifconfig bridge0 addm vr0 addm vr1
shagshag# ifconfig bridge0 ether 00:00:24:c8:e2:28 inet 192.168.1.201/24
ifconfig: can't set link-level netmask or broadcast
shagshag#
So the problem is really when I try to add both an INET address (same
problem with DHCP) and a mac address (tried both with "ether" and "link"
keywords, same result) in the same command line.
And this is really a big problem for me, as I want in my rc.conf something like:
ifconfig_bridge0="addm vr0 addm vr1 inet 192.168.1.201/24 link 00:00:24:c8:e2:28"
>How-To-Repeat:
Set up a bridge, then do:
ifconfig bridge0 ether 00:00:24:c8:e2:28 inet 192.168.1.201/24

No patch, sorry.....
