similar to: bonding driver with arp detection

Hi all, i recently found that some frontend servers (Centos6) show: kernel: bonding: bond0: link status definitely up for interface eth2. kernel: bonding: bond0: link status definitely down for interface eth2, disabling it kernel: bonding: bond0: link status definitely up for interface eth2. On some days frequently and on others none. But there is no hw failure or similar. $ cat

Hello I have two linux machines connected via 2 dsl lines (bonded) 192.168.0.1-eth0-dsl---2Mbit---dsl-eth0-192.168.0.2 ^-eth1-dsl---2Mbit---dsl-eth1-^ so the final figure is something like this: 192.168.0.1-bond0---4Mbit---bond0-192.168.0.2 I can only use arp monitoring for fail checking - if one dsl line fails - automatically use only the other one. I set up everything correctly (i

Hi everyone After configuring bonding eth0 and eth1 in domU, "cat /proc/net/bonding/bond0" showed it was configured correctly. ----------------------------------------------------------------------------------------- Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth1 Currently Active Slave: eth1 MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms):

I don''t know if there was a problem in the archive or not, I just wanted to link to this post of mine, but I could not find it in the archive.

I''m using bonding in active-fallback mode to guarantee maximum availability on some critical servers. The mii mode is active so I can detect things like dead card and/or unplugged cable even on the inactive slave. But how do I check that the inactive slave is properly configured/connected to the switch/vlan? I ask this question because it has just bitten me in a part I''ll keep

I four nodes setup to do active-backup bonding and the drivers loaded for the bonded network interfaces vary between tg3 and e100. All interfaces with the e100 driver loaded report errors much like what you see here: bonding: bond0: link status definitely down for interface eth2, disabling it e100: eth2: e100_watchdog: link up, 100Mbps, full-duplex bonding: bond0: link status definitely up for

CentOS 6.2......... Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond? ----------------------------------------------------------------------------------------- ethtool em1 Settings for em1: Supported ports: [

Hello, I have a CentOS 7.3 + updates server where my configuration arises from the need to connect via iSCSI to a Dell PS Series storage array and Dell not supporting bonding. So that I need to use 2 nics on the same vlan to connect to iSCSI portal IP and then use multipath. Also, the iSCSI lan is on a dedicated vlan I have only these 2 x 10Gbit adapters and I also need to put other vlans on them

I have nic bonding (mode=802.3ad) setup on 2 servers, both running Centos 5.5 In the "Active Aggregator Info", on one reports 4 ports - which is correct - but the other only reports 3 ports. It's always eth0 that shows a different aggregator ID. Changing the cables around so it hits a different port on the switch makes no difference. The switch is correctly configured for the port

HI All. I have a linux box connected to a switch network with 2 network interfaces, how would I able to ''trunk'' 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

Hi, I have been playing this weekend with bonding on PCI netcards and found that all of netcards I have, but old 3com, do not support MII. So bonding is not going to happen with them. Do you have some pci netcards supporting MII successfully running on bonging? Thanks, David Hrb??

*Hi all, I''m not quiet sure the most reasonable way to dealing with bonding on xenserver. My configuration is as follow. It was ok if i do nothing, but When I tried to ''service network restart'', the bond is break. Then, /proc/net/bonding/pbond: Slave Interface: eth0 eth1 was down bonding MII status: down My questions are: how to deal with this situation? how to avoid

As the issue concerns both the -user (configuration) and -devel (OOPS), I''m sending this message to both lists. Some time ago I complained about two problems: - VLANs are not working on machines with 100 Mbit cards - I get a kernel Oops (sometimes panic) when I try to use bonding and VLANs with Xen The root of the issue is the same in both cases: VLAN interfaces must *not* be

Hi, I have 2 servers running CentOS 6.3. Each has four 1gb Ethernet ports. I have bonded all four ports on each server and patched them to the same switch (following the instructions at http://wiki.centos.org/TipsAndTricks/BondingInterfaces). I have created aggregated trunks for the servers respective ports on the switch. The switch reports that the ports are up and that the Link Aggregation is

Hi all, we are testing CentOS 7 in order to migrate from Scientific Linux 6 / CentOS 6 and we are facing an issue with the network. Trying to configure network with teaming in activebackup mode or also with bonding in mode=1 (active backup as well) we see many RX dropped packets in the bond0 interface (around 10% of the total), 100% RX drops in the backup interface and 0% in the active interface.

With the current talk on bonding, I have a few questions of my own. I'm setting up a KVM host with CentOS 6.3 x86_64 on which I'd like to attach the VMs to a bonded interface. My target setup is one where two GigE NICs are bonded and then the KVM bridge interface is attached to the bonded interface. Initially I tried to use the balance-alb mode (mode6), but had little luck (receiving

Guys, good afternoon I'm using in my bond interfaces as active backup, in theory, should assume an interface (or work) only when another interface is down. But I'm just lost packets on the interface that is not being used and is generating packet loss on bond. What can that be?
