Deleting security groups in the CLI

To delete a security group, use the openstack security group delete command and specify the ID or name of the security group:

openstack security group delete <group> [<group> ...] 

To delete a security group named MySampleSecGrp, you can enter the following command:

openstack security group delete MySampleSecGrp 

Alternatively, you can use the group's ID:

openstack security group delete f8ch3db3-e25b-4760-972a-cb700d9a73dc 

Multiple security groups can also be deleted simultaneously, as follows:

openstack security group delete MySampleSecGrp MyOtherSampleSecGrp 

Neutron will successfully delete the security group(s) as long as ports utilizing the group(s) have been deleted prior to the request.
