[Xen-users] bond/trunk in xen

[Srija G <srijavg@xxxxxxxxx>]

Hi ,

  I am trying to configure  bond/trunk  on RHEL 5.4 86_64 OS.

 The bond/trunk works  when I am using mode=1, ie fault-tolerance (active-backup)

 But when I am trying to configure with mode=4, ie 802.3ad Dynamic link aggregation,

  it is not working. 

  Here is the configuration I did:

  -  Considering one  port for bonding ,  now only eth1 as it is a test server has only one port 

  -  the 3 subnets are being considered 12- 14

  -  Included bonding drivers.  and the /etc/modprobe.conf mentioned the parameters as

     alias bond0 bonding
     options bond0 mode=4 miimon=100 lacp_rate=1

  -  In /etc/sysconfig/network-scripts area created few config files as follows;

      ifcfg-bond0  :  DEVICE=bond0
                      BOOTPROTO=none
                      >                      Type=Ethernet
        

      ifcfg-eth1   :  DEVICE=eth1   
                      USERCTL=no
                      >                      MASTER=bond0
                      BOOTPROTO=none
                      HWADDR=xx:xx:xx:xx:xx:xx 
                      SLAVE=yes

    
      ifcfg-bond0.12 :  DEVICE=bond0.12
                        >                        TYPE=Ethernet
                        BOOTPROTO=static
                        IPADDR=xxx.xx.xx.xx
                        NETMASK=255.255.255.0
                        VLAN=yes

      Similarly created ifcfg-bond0.13 and ifcfg-bond.14 like ifcfg-bond0.12

   -  Here is the switch side configuration:

      interface Port-channel60
      description <server> trunk/channel
      switchport trunk allowed vlan 1,12-14,460
      switchport mode trunk
      spanning-tree portfast trunk
      end

      xxx-es-bcs1#sh run int g1/0/4        
      Building configuration...

      Current configuration : 192 bytes
       !
      interface GigabitEthernet1/0/4
      description <server> trunk
      switchport trunk allowed vlan 1,12-14,460
      switchport mode trunk
      channel-group 60 mode active
      spanning-tree portfast trunk
      end

   -  Kept  tag 460 for future use ..

   -  I am getting the file  in /proc/net/bonding/pbond0  not bond0,  here is the display

      Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008)

Similary  the other two subnets also.....

 Really appreceated if anybody helps me out. 

Thanks in advance
