How does the ifenslave command relate to "normal" network slave configuration in /etc/sysconfig/network-scripts? Does config-file-based setup use ifenslave or is it more complicated than that? Thanks....Nick

Hi, This may sound crazy but I will go ahead anyway. Here's my scenario: ifconfig bond0 10.10.10.1 netmask 255.0.0.0 ifenslave bond0 eth0 ifenslave bond0 eth1 brctl addbr stp0 brctl addif stp0 bond0 brctl stp stp0 on Is this a valid scenario? I am trying to bond two interfaces and run STP over the bonded interface..The problem I am trying to solve is to run STP over aggregated links between two nodes. Any suggestions/poi...

...' these 2 interfaces? options I can see are: - ethernet bonding - iproute2? - teql Which one are the best to use? I''m curretly having problem with ethernet bonding, my setup are as follow: ip add: 192.168.10.30/24 I do: # modprobe bonding # ip addr add 192.168.10.30/24 dev bond0 # ifenslave bond0 eth0 # ifenslave bond0 eth1 # ip link set bond0 up At this stage, I can''t ping any of the other workstations / server in 192.168.10.0/24 subnet. I run tcpdump on both the bonding machine and the server I am pinging, I can see the bonding machine keeps sending arp request, the serve...

Hi, Hopefully this won''t be too off-topic (I''ve seen both bonding & vlan mentioned on the list, but not really together). I''ve tried to get bonding (2 x 100Mb EEPro, but will want to try on 1000BaseT) and vlans to work together, but without luck. I can get them working fine (seemingly at least - I didn''t tried bursting on the bonded port) individually.

...m... your nice HA node is off-line. note: eth2 is still plugged and fine at the mii level. even an arp would return OK so going from mii to arp for the bond is not the right option. So. How could I check that an IP packet send via eth2 would really reach its vlan? I tried a probably naive thing: ifenslave -d bond0 eth2 ifconfig eth2 $ip netmask 255.255.255.255 route add -host $target eth2 ping $target (target is the gateway, ip is a reserved IP used only on this server to do that check) but it does not work as I hopped. Sometimes the ping is OK (but goes thru bond0) sometimes it blocks... The real...

...t now, you can configure most bridge device parameters via sysfs. However, you cannot either: - add or remove bridge interfaces - add or remove physical interfaces from a bridge The attached patch set rectifies this. With this patch set, brctl (theoretically) becomes completely optional, much like ifenslave is now for bonding. (In fact, the idea for this patch, and the syntax used herein, is inspired by the sysfs bonding configuration.) Patchset is against net-next-2.6, but should apply to anything reasonably recent with minimal fuzz. Bill Nottingham (2): Add a 'bridging_masters' file in s...

Setting up bonding in active-backup mode 1 (using ARP monitoring) on a server, it looked OK, but pulling the active link cable didn't actually work, it didn't fail over. Eventually with manual playing around with modprobe, ifconfig, ifenslave, etc., a solution was stumbled upon: enslave the eth1 device before eth0, and all is good. Why this should matter is a puzzle - I could not find anything in bonding.txt or on the web about it. I had to change ifup-eth to fix the problem. Any ideas on why the enslavement order matters, or a bette...

Greetings all. This has been an ongoing issue for me for a few months, and I''ve been trying to get an answer. My server has two NICs, and I want to set up the following: NICs (x2) -> bond (mode 5) -> Xen Bridge -> Doms ...however, trying to configure this doesn''t seem to work: network-bridge steals eth0 instead of bond0, which breaks the bond AND my networking.
