similar to: bonding theory question

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.

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

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, may be there are some best practice suggestions for the "best mode" for channel bonding interface? Or in other words, when should/would I use which mode? E.g. I do have some fileservers connected to the users lan and to some ISCSI Storages. Or some Webservers only connected to the LAN. The switches are all new cisco models. I've read sone docs (1), (2) and (3) so the theory

Hi, I am currently struggling with the right way to configure a bonding device via kickstart (via PXE). I am installing servers which have "eno" network interfaces. Instead of the expected bonding device with two active slaves (bonding mode is balance-alb), I get a bonding device with only one active slave and an independent, non-bonded network device. Also the bonding device

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

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, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

(first post) Dear all, I have been wrestling with this issue for the past few days ; googling around doesn't seem to yield anything useful, hence this cry for help. Setup : - I am running several RHEL5.4 KVM virtio guest instances on a Dell PE R805 RHEL5.4 host. Host and guests are fully updated ; I am using iperf to test available bandwidth from 3 different locations (clients) in the

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??

I'm try to bond a few interfaces together with the hopes of getting increased throughput, and I'm using a cisco Catalyst 2900 as the switch. I've tried using mode 0, 5, and 6 with nothing special on the switch, and mode 4 with some ports "trunked" together (I have a feeling that the "trunking" that the 2900 does is not 802.3ad, as it disabled the ports it saw as

Hi, I have 2 NIC and wants to use both NIC for load balancing and fault tolerance. - Quick question if NIC bonding in Redhat is supported by OCFS2? - If yes which mode bonding is supported? Thanks Raheel -------------- next part -------------- An HTML attachment was scrubbed... URL:

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 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

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

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?
