  • network
  • priority
  • routine

proto
-
Port number or protocol (as supported by the switch).
provider
dictionary
Deprecated
Starting with Ansible 2.5 we recommend using connection: network_cli.
This option is only required if you are using NX-API.
For more information please see the NXOS Platform Options guide.
A dict object containing connection details.
auth_pass
string
added in 2.5.3
Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTH_PASS will be used instead.
authorize
boolean
added in 2.5.3
    Choices:
  • no ←
  • yes
Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTHORIZE will be used instead.
host
string / required
Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
password
string
Specifies the password to use to authenticate the connection to the remote device. This is a common argument used for either cli or nxapi transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
port
integer
Default:
"0 (use common port)"
Specifies the port to use when building the connection to the remote device. This value applies to either cli or nxapi. The port value will default to the appropriate transport common port if none is provided in the task. (cli=22, http=80, https=443).
ssh_keyfile
string
Specifies the SSH key to use to authenticate the connection to the remote device. This argument is only used for the cli transport. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
timeout
integer
Default:
10
Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error. NX-API can be slow to return on long-running commands (sh mac, sh bgp, etc).
transport
string / required
    Choices:
  • cli ←
  • nxapi
Configures the transport connection to use when connecting to the remote device. The transport argument supports connectivity to the device over cli (ssh) or nxapi.
use_proxy
boolean
added in 2.5
    Choices:
  • no
  • yes ←
If no, the environment variables http_proxy and https_proxy will be ignored.
use_ssl
boolean
    Choices:
  • no ←
  • yes
Configures the transport to use SSL if set to yes only when the transport=nxapi, otherwise this value is ignored.
username
string
Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate either the CLI login or the nxapi authentication depending on which transport is used. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead.
validate_certs
boolean
    Choices:
  • no
  • yes ←
If no, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. If the transport argument is not nxapi, this value is ignored.
psh
-
    Choices:
  • enable
Match on the PSH bit.
remark
-
If action is set to remark, this is the description.
rst
-
    Choices:
  • enable
Match on the RST bit.
seq
-
Sequence number of the entry (ACE).
src
-
Source ip and mask using IP/MASK notation and supports keyword 'any'.
src_port1
-
Port/protocol and also first (lower) port when using range operand.
src_port2
-
Second (end) port when using range operand.
src_port_op
-
    Choices:
  • any
  • eq
  • gt
  • lt
  • neq
  • range
Source port operands such as eq, neq, gt, lt, range.
state
-
    Choices:
  • present ←
  • absent
  • delete_acl
Specify desired state of the resource.
syn
-
    Choices:
  • enable
Match on the SYN bit.
time_range
-
Name of time-range to apply.
urg
-
    Choices:
  • enable
Match on the URG bit.

Notes

Note

  • Tested against NXOSv 7.3.(0)D1(1) on VIRL

  • state=absent removes the ACE if it exists.

  • state=delete_acl deletes the ACL if it exists.

  • For idempotency, use port numbers for the src/dest port params like src_port1 and names for the well defined protocols for the proto param.

  • Although this module is idempotent in that if the ace as presented in the task is identical to the one on the switch, no changes will be made. If there is any difference, what is in Ansible will be pushed (configured options will be overridden). This is to improve security, but at the same time remember an ACE is removed, then re-added, so if there is a change, the new ACE will be exactly what parameters you are sending to the module.
