Neutron Quota is used to manage operational limits for projects. Currently,
|
|
this resource can manage Neutron's quotas for:
|
|
- subnet
|
|
- network
|
|
- floatingip
|
|
- security_group_rule
|
|
- security_group
|
|
- router

|
- port

Note that default neutron security policy usage of this resource
|
|
is limited to being used by administrators only. Administrators should be
|
|
careful to create only one Neutron Quota resource per project, otherwise
|
|
it will be hard for them to manage the quota properly.
