|
notes:
|
|
- Either C(sysmtu) param is required or C(interface) AND C(mtu) params are req'd.
|
|
- C(state=absent) unconfigures a given MTU if that value is currently present.
|
|
options:
|
|
interface:
|
|
description:
|
|
- Full name of interface, i.e. 40GE1/0/22.
|
|
mtu:
|
|
description:
|
|
- MTU for a specific interface.
|
|
The value is an integer ranging from 46 to 9600, in bytes.
|
|
jumbo_max:
|
|
description:
|
|
- Maximum frame size. The default value is 9216.
|
|
The value is an integer and expressed in bytes. The value range is 1536 to 12224 for the CE12800
|
|
and 1536 to 12288 for ToR switches.
|
|
jumbo_min:
|
|
description:
|
|
- Non-jumbo frame size threshod. The default value is 1518.
|
|
The value is an integer that ranges from 1518 to jumbo_max, in bytes.
