Chapter 24 Network Segmentation Manager
Problems with Network Segmentation Manager
The network creation triggered from
vCloud Director fails. A system
message similar to the following is
logged in the vCloud Director:
Failed to create network
segment
vCloud Director is unable to create
the VLAN associated with the
network.
1.
Verify that the resources are available to
create a VLAN by checking the existing
number of VLAN.
show vlan summary
If the number of existing VLANs exceeds
the number of supported VLANs (2048),
then evaluate if there are any of the VLANs
that can be removed from the system.
2.
Verify that the VLAN pool in vCloud
Director does not contain more than 2048
available VLANs.
The network creation triggered from
vCloud Directors fail. A system
message similar to the following is
logged in vCloud Director:
Template could not be
inherited on port-profile
vCloud Director is unable to inherit
the port profile associated with the
network segment policy onto the
port profile created for the network.
1.
Verify if the port profile exists.
show running-config port-profile
name
To identify the name of the port profile, you
will need to determine the network segment
policy the network was attempting to use.
You will need the information about the
tenant/organization UUID and the type of
network pool the network was being created
from (VXLAN or VLAN) to find the
corresponding network segment policy that
has these values configured. If no network
segment policy is configured with these
values, then use the default network segment
policy to identify the name of the port
profile.
2.
Check the system logs for a port profile
inheritance failure message reported by
network segmentation manager. See the
Cisco NX-OS System Messages Reference
for more information.
The network creation triggered from
vCloud Director fails. A system
message similar to the following is
logged in the vCloud Director:
Failed to set max-ports
vCloud Director is unable to set the
max ports on the port profile.
Check system logs for a maximum number of
port failure message reported by NSM. See the
Cisco NX-OS System Messages Reference
for
more information.
The network creation triggered from
vCloud Director fails. A system
message similar to the following is
logged in vCloud Director:
Network already exists
A network with the same name
already exists in the vCloud
Director.
1.
Delete the existing network that has the
same name.
no port-profile
network name
2.
Delete the bridge domain with the same
name if it exists.
no bridge-domain
name
