nxos_mtu - Manages MTU settings on Nexus switch.

New in version 2.2.

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.
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.
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. The value of username 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.

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 Common 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'] dict {'sysmtu': '9216', 'mtu': '1600'}

Notes

Note

Either sysmtu param is required or interface AND mtu params are req’d.

Note

state=absent unconfigures a given MTU if that value is currently present.
