Details:
vlan_bindings: map of integer-Logical_Switch pairs, key in range
0 to 4,095
Identifies how VLANs on the physical port are bound to
logical switches. If, for example, the map contains a
(VLAN, logical switch) pair, a packet that arrives on the
port in the VLAN is considered to belong to the paired
logical switch. A value of zero in the VLAN field means
that untagged traffic on the physical port is mapped to
the logical switch.
acl_bindings: map of integer-ACL pairs, key in range 0 to 4,095
Attach Access Control Lists (ACLs) to the physical port.
The column consists of a map of VLAN tags to ACLs. If the
value of the VLAN tag in the map is 0, this means that the
ACL is associated with the entire physical port. Non-zero
values mean that the ACL is to be applied only on packets
carrying that VLAN tag value. Switches will not
necessarily support matching on the VLAN tag for all ACLs,
and unsupported ACL bindings will cause errors to be
reported. The binding of an ACL to a specific VLAN and the
binding of an ACL to the entire physical port should not
be combined on a single physical port. That is, a mix of
zero and non-zero keys in the map is not recommended.
vlan_stats: map of integer-Logical_Binding_Stats pairs, key in
range 0 to 4,095
Statistics for VLANs bound to logical switches on the
physical port. An implementation that fully supports such
statistics would populate this column with a mapping for
every VLAN that is bound in vlan_bindings. An
implementation that does not support such statistics or
only partially supports them would not populate this
column or partially populate it, respectively. A value of
zero in the VLAN field refers to untagged traffic on the
physical port.
Identification:
name: string
Symbolic name for the port. The name ought to be unique
within a given Physical_Switch, but the database is not
capable of enforcing this.
description: string
An extended description for the port.
Error Notification:
An entry in this column indicates to the NVC that the physical
port has encountered a fault. The switch must clear this column
when the error has been cleared.
port_fault_status : invalid_vlan_map: none
Indicates that a VLAN-to-logical-switch mapping requested
by the controller could not be instantiated by the switch
because of a conflict with local configuration.
port_fault_status : invalid_ACL_binding: none
Indicates that an error has occurred in associating an ACL
with a port.
port_fault_status : unspecified_fault: none
Indicates that an error has occurred on the port but that
no more specific information is available.
Common Column:
The overall purpose of this column is described under Common
Column at the beginning of this document.
