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

Silvertip257, when you did this CentOS 6/KVM/bonding/bridging, did you ever get all the parts playing together correctlhy? I'm facing a setup with only two NIC's, and need for multiple trunked VLAN access, and bonded pairs, and KVM based bridges to get the VM's with exposed IP addresses. I can get basically any 2 out of the 3 server network components working, binding, VLAN's, or

I''m experiencing a problem with XenEnterprise migration for a Windows 2008 server VM where a large % of the time I notice a 45-50 sec delay after the VM has been migrated to the other side. I''m wondering if anyone in this list is using XenEnterprise and has tried W2k8 migrations. Thanks in advance. W2K8 online migration delays guest execution 45-50 seconds Posted: Mar

I have a bonded interface running in mode 1 which is active/passive and no issue with this. I need to change it to mode 0 for active/active setup. Does mode 0 is dependent on the switches configuration? My setup is: 2 links from bonded interface is connected to different switches. When I change to mode0 from mode1 , bond0 is not coming up. These are the steps I performed 1) changed to options

HI, I have been pulling my hair out trying to get a Cisco MC3810 to interface my Asterisk box with a T1. I am able to make outgoing calls but incoing calls never reach my Asterisk box. The cisco give a fast busy when I try to call one of the DID's. When playing around with the dial-peers I can get the cisco to pick up the call, but then it forwards the call back to the ANI that is dialing.

Since I upgraded from 4.4 to 4.5 my system which has 2 sets of ALB bonded interfaces hangs on shutdown while doing an ifdown on these interfaces. Has anyone else seen this issue with 4.5 and bonding?

Hi folks, I am stuck with a weird phenomenon. I have set up two servers as xen servers with bonded interfaces (mode 1). The bond interface works fine on both servers as long as xen is not used. When using xen's network-bridge script (with netdev=bond0), one server works fine without problems, and the other starts upping and downing the slave interfaces of the bond in a very fast manner

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, 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

I have a Dell server with four bonded, gigabit interfaces. Bonding mode is 802.3ad, xmit_hash_policy=layer3+4. When testing this setup with iperf, I never get more than a total of about 3Gbps throughput. Is there anything to tweak to get better throughput? Or am I running into other limits (e.g. was reading about tcp retransmit limits for mode 0). The iperf test was run with iperf -s on the

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24

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

Hi all, Just wondering if any one has experienced problems with trying to bridge a bonded interface with your KVM guests? There may be some ARP issues as per this link; https://bugzilla.redhat.com/show_bug.cgi?id=584872 Thanks in advance, - aurf

Hi folks, I have a server where I have solved the well known problem with a bonding interface as netdev on Xen/Centos 5.x (current: 5.2) - the problem is, that in mode=1 (active-passive) the slave interfaces are de-/activated round robin at least once a second. "network-bridge stop netdev=bond0" stops this nonsense and makes the bonded interface work well again. I had to do change 3

I am able to bring up a bonded NIC in Centos4 without requiring to bring up the bond0 with an ip address, but with CentOS-3 I must assign the NIC an address or eth0 and eth1 will not slave. I need to bring bond0 up without an ip address becuase I will be using tagged VLANs. ie. <snip /etc/sysconfig/network-scripts/ifcfg-bond0> DEVICE=bond0 BOOTPROTO=none ONBOOT=yes IPADDR=169.254.0.1
