unable to update floating IP from openstack CLI

[balakrishnan]

Trying to update floating IP to the port using openstack CLI command.
getting Error "floating ip set" is not an openstack command while executing.

But the below link says the command is available.
https://docs.openstack.org/python-openstackclient/latest/cli/command-objects/floating-ip.html#floating-ip-set

[root@control-packstack ~(keystone_admin)]# openstack floating ip set --port c2b05f1c-6f4a-4b98-a45a-15a04eec32b4 --fixed-ip-address 10.0.0.10 192.165.1.6
openstack: 'floating ip set --port c2b05f1c-6f4a-4b98-a45a-15a04eec32b4 --fixed-ip-address 10.0.0.10 192.165.1.6' is not an openstack command. See 'openstack --help'.
Did you mean one of these?
  floating ip create
  floating ip delete
  floating ip list
  floating ip pool list
  floating ip show
  container create
  container delete
  container list
  container save
  container set
  container show
  container unset

any specific version of python clien is needed?
i am using packstack ocata in my environment.

The command is available in version 3.11.0, not sure when it was introduced. Since your distro doesn't have a new enough version, you may need to install it via pip.
