description:
|
|
- The description to give to the VLAN.
|
|
tagged_interfaces:
|
|
description:
|
|
- Specifies a list of tagged interfaces and trunks that you want to
|
|
configure for the VLAN. Use tagged interfaces or trunks when
|
|
you want to assign a single interface or trunk to multiple VLANs.
|
|
aliases:
|
|
- tagged_interface
|

untagged_interfaces:

description:
|
|
- Specifies a list of untagged interfaces and trunks that you want to

configure for the VLAN.

- The VLAN to manage. If the special VLAN C(ALL) is specified with
|
|
the C(state) value of C(absent) then all VLANs will be removed.
|
|
required: True
|
|
state:
|
|
description:
|
|
- The state of the VLAN on the system. When C(present), guarantees
|
|
that the VLAN exists with the provided attributes. When C(absent),
|
|
removes the VLAN from the system.
|
|
default: present
|
|
choices:
|
|
- absent
|
|
- present
|
|
tag:
|
|
description:
|
|
- Tag number for the VLAN. The tag number can be any integer between 1
|
|
and 4094. The system automatically assigns a tag number if you do not
|
|
specify a value.
|
|
mtu:
|
|
description:
|
|
- Specifies the maximum transmission unit (MTU) for traffic on this VLAN.
|
|
When creating a new VLAN, if this parameter is not specified, the default
|
|
value used will be C(1500).
|
|
- This number must be between 576 to 9198.
|
|
version_added: 2.5
|
|
cmp_hash:
|
|
description:
|
|
- Specifies how the traffic on the VLAN will be disaggregated. The value
|
|
selected determines the traffic disaggregation method. You can choose to
|
|
disaggregate traffic based on C(source-address) (the source IP address),
|
|
C(destination-address) (destination IP address), or C(default), which
|
|
specifies that the default CMP hash uses L4 ports.
|
|
- When creating a new VLAN, if this parameter is not specified, the default
|
|
of C(default) is used.
|
|
choices:
|
|
- default
|
|
- destination-address
|
|
- source-address

|
|
dag_tunnel:
|
|
description:
|
|
- Specifies how the disaggregator (DAG) distributes received tunnel-encapsulated
|
|
packets to TMM instances. Select C(inner) to distribute packets based on information
|
|
in inner headers. Select C(outer) to distribute packets based on information in
|
|
outer headers without inspecting inner headers.
|
|
- When creating a new VLAN, if this parameter is not specified, the default
|
|
of C(outer) is used.
|
|
- This parameter is not supported on Virtual Editions of BIG-IP.
|
|
version_added: 2.5
|
|
choices:
|
|
- inner
|
|
- outer
|
|
dag_round_robin:
|
|
description:
|
|
- Specifies whether some of the stateless traffic on the VLAN should be
|
|
disaggregated in a round-robin order instead of using a static hash. The
|
|
stateless traffic includes non-IP L2 traffic, ICMP, some UDP protocols,
|
|
and so on.
|
|
- When creating a new VLAN, if this parameter is not specified, the default
|
|
of (no) is used.
