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.
host
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.
port 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).
username
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.
password Default:
None
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.
authorize
(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.
auth_pass
(added in 2.5.3)
Default:
none
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.
timeout
(added in 2.3)
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).
ssh_keyfile
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.
transport
required
Default:
cli
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_ssl
    Choices:
  • yes
  • no ←
Configures the transport to use SSL if set to true only when the transport=nxapi, otherwise this value is ignored.
validate_certs
    Choices:
  • yes
  • no
Default:
None
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.
use_proxy
(added in 2.5)
    Choices:
  • yes ←
  • no
If no, the environment variables http_proxy and https_proxy will be ignored.
reconnect_interval Default:
None
The BGP reconnection interval for dropped sessions. Valid values are between 1 and 60.
router_id Default:
None
Router Identifier (ID) of the BGP router VRF instance.
shutdown
    Choices:
  • true
  • false
Default:
None
Administratively shutdown the BGP protocol.
state
    Choices:
  • present ←
  • absent
Determines whether the config should be present or not on the device.
suppress_fib_pending
    Choices:
  • true
  • false
Default:
None
Enable/Disable advertise only routes programmed in hardware to peers.
timer_bestpath_limit Default:
None
Specify timeout for the first best path after a restart, in seconds.
timer_bgp_hold Default:
None
Set BGP hold timer.
timer_bgp_keepalive Default:
None
Set BGP keepalive timer.
vrf Default:
None
Name of the VRF. The name 'default' is a valid VRF representing the global BGP.

Notes

Note

  • Tested against NXOSv 7.3.(0)D1(1) on VIRL
  • state=absent removes the whole BGP ASN configuration when vrf=default or the whole VRF instance within the BGP process when using a different VRF.
  • Default when supported restores params default value.
  • Configuring global parmas is only permitted if vrf=default.
  • For information on using CLI and NX-API see the NXOS Platform Options guide
  • For more information on using Ansible to manage network devices see the Ansible Network Guide
  • For more information on using Ansible to manage Cisco devices see the Cisco integration page.
