nxos_mtu - Manages MTU settings on Nexus switch.

New in version 2.2.

DEPRECATED

Removed in Ansible:
version: 2.5
Why: Replaced with common *_system network modules.
Alternative: Use nxos_system’s system_mtu option. To specify an interfaces MTU use nxos_interface.

Synopsis

  • Manages MTU settings on Nexus switch.

Parameters

Parameter Choices/Defaults Comments
interface
Full name of interface, i.e. Ethernet1/1.
mtu
MTU for a specific interface. Must be an even number between 576 and 9216.
provider
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
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
bool

(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
bool
    Choices:
  • no ←
  • yes
Configures the transport to use SSL if set to true only when the transport=nxapi, otherwise this value is ignored.
validate_certs
bool
    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.
use_proxy
bool

(added in 2.5)
    Choices:
  • no
  • yes ←
If no, the environment variables http_proxy and https_proxy will be ignored.
state
    Choices:
  • present ←
  • absent
Specify desired state of the resource.
sysmtu
System jumbo MTU. Must be an even number between 576 and 9216.

Notes

Note

  • Tested against NXOSv 7.3.(0)D1(1) on VIRL
  • Either sysmtu param is required or (interface AND mtu) parameters are required.
  • state=absent unconfigures a given MTU if that value is currently present.
  • 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.

Examples

# Ensure system mtu is 9126
- nxos_mtu:
    sysmtu: 9216
    host: "{{ inventory_hostname }}"
    username: "{{ un }}"
    password: "{{ pwd }}"

# Config mtu on Eth1/1 (routed interface)
- nxos_mtu:
    interface: Ethernet1/1
    mtu: 1600
    host: "{{ inventory_hostname }}"
    username: "{{ un }}"
    password: "{{ pwd }}"

# Config mtu on Eth1/3 (switched interface)
- nxos_mtu:
    interface: Ethernet1/3
    mtu: 9216
    host: "{{ inventory_hostname }}"
    username: "{{ un }}"
    password: "{{ pwd }}"

# Unconfigure mtu on a given interface
- nxos_mtu:
    interface: Ethernet1/3
    mtu: 9216
    host: "{{ inventory_hostname }}"
    username: "{{ un }}"
    password: "{{ pwd }}"
    state: absent
