Vlans and bonded devices

Mike Hedderly — Tue, 23 May 2006 06:22:26 GMT

I have just installed the HP PSP pack 7.51 for linux and my vlans have stopped working. It seems that there is a new script vlan used for startup and a config file vlan.conf.

The network scripts should have all ip information removed and added to vlan.conf
bond0 11 192.168.1.1 255.255.255.128
bond0 12 192.168.2.1 255.255.255.128
bond0 13 10.1.1.1 255.255.255.128

which I have , the trounle is after the restart it has marked bond0 as inactive. the vlan.txt file is not clear. Does anyone have an example of a vlan.conf file for bonded vlans.

Thanks

I will reply with your answer soon.

Let me put together all the files that need attention.

Thanks for the update thats very sumilar to what I have. I have bond0 which is the primary interface and 3 vlans bond0.11 12 13

But there has been the introduction of a new script vlan on startup this creates the vlans and then marks bond0 with an ip address of 0.0.0.0

This is the section of code
and this is my Vlan.conf
# Sample Entry for 2 vlan's created with VLAN_ID=4092
# and VLAN_ID=4093 over a bonding interface bond0

#bond0 4092 10.10.10.1 255.255.255.0
#bond0 4093 10.10.20.1 255.255.255.0
bond0 11 192.168.1.1 255.255.255.128
bond0 12 192.168.2.1 255.255.255.128
bond0 13 10.1.1.1 255.255.255.128

However - there is no reference on what to do with the bond0 device. I have tried to uncomment the bond0 network script. But the Vlan startup scripts marks bond0 as 0.0.0.0 and this is the offending lines

vif=`cat $VLANPROCDIR/config | egrep "$iface" | egrep $vlan_id |
awk -F'|' '{print $1}' | sed 's/ //g'`
/sbin/ifconfig $vif $ip_addr netmask $netmask up
/sbin/ifconfig $iface 0.0.0.0
