I am trying to use the nexus1000v with VXLAN as part of a vCloud Director setup, when i come to use the network pool for a VM i receive the following error on the 1000v switch.
2013 Mar 25 14:47:17.720 blob %NSMGR-3-NETWORK_CREATE_FAILED: Network 'vxw-dvs-49 -virtualwire-4-sid-10000-dvs.VCDVSVXLAN-042f31b1-f3d4-40e3-9fdd-34bebd' creation failed with error "Failed to create bridge domain" (Additional information: Syntax error while parsing 'bridge-domain "vxw-dvs-49-virtualwire-4-sid-1
the configuration i have is aswell follows,
network-segmentation 1 enabled
port-profile type vethernet -VXLAN-A
vmware port-group VXLAN-A
switchport access vlan 10
port-profile type ethernet VXLAN
vmware port-group vxlan-uplink
switchport mode trunk
switchport trunk allowed vlan 10
channel-group auto mode on sub-group cdp
system vlan 10
all traffic this then passed to the upstream Cisco UCS
anyone got any ideas on the error?
You config is deffinitely wrong above.
For port-profile VXLAN-A add "system vlan 10"
For the uplink port-profile if you are using Cisco UCS Blades change the channel-group to
channel-group auto mode on mac-pinning
You are allowing vlan 10 on the trunk port but your system vlan is 3085 which is not allowed. You need to add vlan 3085 to the trunk allowed list and add vlan 10 to the system vlan settings.
There are some other configs on the vCloud side that you need to make sure work. First check the compatibility. Make sure the N1KV version you have is correct for the vCloud version you are trying to run. This is listed in the compatibility matrix.
On the vcloud side you need to make sure the segments are setup on the vShield Edge Manager.
Make the fixes to the above port-profiles, verify your vShield Edge and let us know what you get after that.
yeah i have modified the vlan its all vlan 10 now.
is there a reason i cannot use channel-group auto mode on sub-group cdp with the Cisco UCS?
i am using version 4.2(1)SV2(1.1), let me check that out
You can use it but it's not recommended. As long as you stick to just two nics one each fabric and you enable CDP on the adapters it will work, but again mac-pinning mode is recommended.
Just to add, using "sub-group cdp" has a reliance on CDP timers... MAC pinning has no such dependecy so there's never any delay during bring up or a failover event.
okay no problem, i have sorted that out, looks like my version is supported and i have followed the correct paths to enable VXLAN but i still get the same errors. not sure what is wrong at the moment
my nexus 1000v version is version 4.2(1)SV2(1.1) but i can see that : 4.2(1)SV1(5.2) is also out, is that the latest version of nexus 1000v
Yeah that guide is missing some N1KV specific detail.
and send me an email at email@example.com and I can email you another guide as well.
You need to enable segmentation feature to use segment bridge domains. Please use "feature segmentation" command to enable it.
