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.
reconnect_interval
-
The BGP reconnection interval for dropped sessions. Valid values are between 1 and 60.
router_id
-
Router Identifier (ID) of the BGP router VRF instance.
shutdown
boolean
    Choices:
  • no
  • yes
Administratively shutdown the BGP protocol.
state
-
    Choices:
  • present ←
  • absent
Determines whether the config should be present or not on the device.
suppress_fib_pending
boolean
    Choices:
  • no
  • yes
Enable/Disable advertise only routes programmed in hardware to peers.
timer_bestpath_limit
-
Specify timeout for the first best path after a restart, in seconds.
timer_bgp_hold
-
Set BGP hold timer.
timer_bgp_keepalive
-
Set BGP keepalive timer.
vrf
-
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 params 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.
