nxos_mtu - Manages MTU settings on Nexus switch.

New in version 2.2.

DEPRECATED

Deprecated in 2.3 use nxos_system‘s mtu option.

Synopsis

  • Manages MTU settings on Nexus switch.

Options

parameter required default choices comments
host
 yes
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.
interface
 no
Full name of interface, i.e. Ethernet1/1.
mtu
 no
MTU for a specific interface. Must be an even number between 576 and 9216.
password
 no
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
 no 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).
provider
 no
Convenience method that allows all nxos arguments to be passed as a dict object. All constraints (required, choices, etc) must be met either by individual arguments or values in this dict.
ssh_keyfile
 no
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.
state
 no present
  • present
  • absent
Specify desired state of the resource.
sysmtu
 no
System jumbo MTU. Must be an even number between 576 and 9216.
timeout
(added in 2.3)
 no 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
 yes 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
 no
  • yes
  • no
Configures the transport to use SSL if set to true only when the transport=nxapi, otherwise this value is ignored.
username
 no
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
 no
  • yes
  • no
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.

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

Return Values

Common return values are documented here Return Values, the following are the fields unique to this module:

name description returned type sample
end_state
k/v pairs of mtu/sysmtu values after module execution
 always dict {'sysmtu"': '9216', 'mtu': '1700'}
changed
check to see if a change was made on the device
 always boolean True
updates
command sent to the device
 always list ['interface vlan10', 'mtu 1700']
proposed
k/v pairs of parameters passed into module
 always dict {'mtu': '1700'}
existing
k/v pairs of existing mtu/sysmtu on the interface/system
 always dict {'sysmtu': '9216', 'mtu': '1600'}

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.
