Re: [Xen-users] vlans+bonding+bridging

Hi,
thanks for immediate help !:-)
It is Cisco switch - but I have no access to it - have to ask network 
responsible to check it.
I have another basic problem - the machine is PE2950 - it seems that 
the two NICs I want to bind together are bound in a way - only one of them 
can get IP address - if both get IP - no  network access to the 
computer

you have to set the ip address on the bond0 interface, set eth4 and
eth5 with no ip address at the boot process. then start bond0 wiht
your ip address. make sure your networking guys set the portchannel
correctly.
as example:

lea# sh run int gi 1/0/29
Building configuration...

Current configuration : 244 bytes
!
interface GigabitEthernet1/0/29
 description sct-ha1-NOC|305:drea
 switchport mode access
 switchport access vlan 12
 switchport nonegotiate
 channel-group 5 mode on
end

lea# sh run int gi 2/0/29
Building configuration...

Current configuration : 244 bytes
!
interface GigabitEthernet2/0/29
 description sct-ha1-NOC|306:drea
 switchport mode access
 switchport access vlan 12
 switchport nonegotiate
 channel-group 5 mode on
end

lea# sh run int po5
Building configuration...

Current configuration : 211 bytes
!
interface Port-channel5
 description etc-TX--ha1-342|drea
 switchport mode access
 switchport access vlan 12
 switchport nonegotiate
end
