| ctVlanVersionNumber |
.1.3.6.1.4.1.52.4.1.2.16.1.1 |
|
Specifies the IEEE 802.1Q VLAN version number.
|
| ctVlanSupportedOperationalMode |
.1.3.6.1.4.1.52.4.1.2.16.1.2 |
|
This value indicates whether the device allows for flexible
VLAN configuration as specified by ctVlanCurrentOperationalMode.
A value of static(1) indicates that the device does not allow
for user configuration.
A value of configurable(2) indicates that the device supports
the functionality described in the ctVlanCurrentOperationalMode
object.
|
| ctVlanCurrentOperationalMode |
.1.3.6.1.4.1.52.4.1.2.16.1.3 |
|
This value indicates the number of bits in a VLAN Id
that are considered significant in the forwarding decision
of a packet. This allows VLANs to be grouped together into
logical units. Within the scope of these VLAN groups, unicast
traffic may be bridged between VLANs, but, multicast and broadcast
traffic is scoped to a specific VLAN.
In the following depiction M represents the number of
significant bits as specified by a set of the object.
An X in a box represents that the bit is considered
significant based on the value of M.
11 10 9 8 7 6 5 4 3 2 1 0
+===============================================+
M=0 | | | | | | | | | | | | |
+===============================================+
11 10 9 8 7 6 5 4 3 2 1 0
+===============================================+
M=4 | | | | | | | | | X | X | X | X |
+===============================================+
11 10 9 8 7 6 5 4 3 2 1 0
+===============================================+
M=9 | | | | X | X | X | X | X | X | X | X | X |
+===============================================+
Significant bits are assigned sequentially starting with bit
zero and ending with bit M-1.
For a set value of M, (2 ^ M) VLAN groups will be created. Each
group will contain (2 ^ (12 - M)) VLAN Ids, with the exception
of the first group and last group which will each have
((2 ^ (12 - M)) - 1) VLAN Ids (VLAN Ids 0 and 4095 are reserved).
VLAN groups are numbered sequentially from 0 through ((2 ^ M) - 1).
The VLAN Ids assigned to each group, N, are assigned sequentially
starting with (N * (2 ^ (12 - M))) through
((N * (2 ^ (12 - M))) + ((2 ^ (12 - M)) - 1)), with the exception
of group zero which always starts with VLAN Id 1 and group
((2 ^ M) -1) which always ends with VLAN Id 4094.
The number of bits specified allows the maximum amount of
flexibility in the scoping of traffic, without compromising
security between VLANS. For example, a set value of 0 would
create a single VLAN group with 4094 VLAN Ids. This configuration
would allow all unicast traffic to be bridged between VLANS,
while scoping all multicast and broadcast traffic to a specific VLAN.
A set value of 12 would restrict all unicast, multicast and broadcast
traffic to a specific VLAN. In this configuration no traffic
would be bridged between VLANS.
Setting of this object is limited to devices which support
configurable(2) operational modes as specified by
ctVlanSupportedOperationalMode. A set of this object for a
device which only supports static(1) operational mode will fail.
A read of this object for a device that only supports
static(1) operational mode will always return 12.
|
| ctVlanResetDefaults |
.1.3.6.1.4.1.52.4.1.2.16.1.4 |
|
A set of the value reset(2) will cause the
ctVlanTriggerPortSet table to contain no entries, delete
all objects from the ctVlanConfig group, and reset the
ctVlanPortVID for each port to the default port VLAN Identifier.
A read of this object will return current(1).
A set of current(1) has no effect.
|
| ctVlanDefaultVIDStickyEgress |
.1.3.6.1.4.1.52.4.1.2.16.1.5 |
|
A set of the value enable(1) will cause
a port, as specified by ctVlanPortNum, to remain in the
egress list for the DEFAULT VLAN (VID 1) when the port's
VID, specified by ctVlanPortVID, is changed. A set of disable(2)
will cause the port to be removed from the egress list of the
DEFAULT VLAN when the ports VID is changed.
|
| ctVlanSupportedPortEntry |
.1.3.6.1.4.1.52.4.1.2.16.1.6.1 |
|
Specifies the bridge ports in the ctVlanSupportedPortTable.
|
| ctVlanLearningMode |
.1.3.6.1.4.1.52.4.1.2.16.1.7 |
|
This value indicates the type of VLAN learning the device supports.
A value of ivl(1) indicates the device supports Independent VLAN
Learning (IVL). Configuration and operation of the Learning Process
and the Filtering Database such that, for a given set of VLANs, if a
given individual MAC address is learnt in one VLAN, that learnt
information is not used in forwarding decisions taken for the same
address relative to any other VLAN in the given set. This
operational mode indicates that all unicast, multicast and broadcast
traffic is scoped to a specific VLAN.
A value of svl(2) indicates the device supports Shared VLAN
Learning (SVL). Configuration and operation of the Learning Process
and the Filtering Database such that, for a given set of VLANs, if a
given individual MAC address is learnt in one VLAN, that learnt
information is used in forwarding decisions taken for the same
address relative to any other VLAN in the given set. In a bridge
that supports SVL operation, the `given set of VLANS' is the set
of all VLANS (1 - 4094). This operational mode allows all unicast
traffic to be bridged between VLANS, while scoping all unknown,
multicast and broadcast traffic to a specific VLAN.
A value of svlivl(3) indicates the device supports both Shared
and Independent VLAN learning simultaneously. This operational
mode allows learnt information to be shared between those VLANS for
which SVL is necessary while also allowing learnt information not to
be shared between those VLANS for which IVL is necessary.
All three of the aforementioned modes operate by placing VLANs in
`sets'. In IVL each VLAN is mapped to a separate set while in SVL
each VLAN is mapped to the same set. Accordingly, svlivl is a
combination of both. Each set is realized as a separate filter
database. Each filter database is uniquely identified by a Filter
Database Identifier (FID). The mapping of VLANs to filter databases
is defined in the ctVlanIdToFidMapping leaf of the ctVlanConfigTable.

.1.3.6.1.4.1.52.4.1.2.16.1.6.1.2 |
|
The set of ports on the device, specified by
ctVlanSupportedSlotNum, that support VLANs.
Each octet within the value of this object specifies
a set of eight ports, with the first octet specifying
ports 1 through 8, the second octet specifying ports 9
through 16, etc. Within each octet, the most significant
bit represents the lowest numbered port, and the least
significant bit represents the highest numbered port.
Thus, each port of the VLAN bridge is represented by a
single bit within the value of this object. If that bit
has a value of '1' then that port is included in the set
of ports; the port is not included if its bit has a value of '0'.
|

trigger functions. Each octet within the value of
this object specifies a set of eight ports, with the
first octet specifying ports 1 through 8, the second
octet specifying ports 9 through 16, etc. Within each
octet, the most significant bit represents the lowest
numbered port, and the least significant bit represents
the highest numbered port. Thus, each port of the VLAN
bridge is represented by a single bit within the value
of this object. If that bit has a value of '1' then
that port is included in the set of ports; the port is
not included if its bit has a value of '0'. A set of '1'
for a port that does not have a '1' for the corresponding
bit in the ctVlanSupportedPortNum will be ignored.

|
The 12 bit Port VLAN Identifier (PVID) associated with the configured
VLAN for received untagged packets on the port specified by
ctVlanPortNum. The port specified by ctVlanPortNum will be added to
the egress list (ctVlanEgressList) for the specified VLAN with
the frame type of untagged, via ctVlanEgressUntaggedList. The port will
be removed from the egress list of the previous PVID. The exception to
this is the DEFAULT VLAN (VID 1) when the ctVlanDefaultVIDStickyEgress
is set to a value of enable(1). Additionally the ctVlanStatus
of the specified VLAN will be set to a value of enable(1). A set of
value that does not exist in the ctVlanConfigTable will fail
with a NO-INSTANCE error.
|
| ctVlanPortDiscardFrame |
.1.3.6.1.4.1.52.4.1.2.16.3.1.1.4 |
|
A set of noDiscard(1) causes the port to submit all packets
received on the port to the forwarding process, regardless,
of the absence or presence of a VLAN tag in the packet.
A set of discardUntagged(2) causes the port specified by ctVlanPortNum
to discard all frames received that carry no VLAN classification
(i.e. any untagged frames or priority tagged frames). A set of
discardTagged(3) has no effect.
|
| ctVlanPortOperationalMode |
.1.3.6.1.4.1.52.4.1.2.16.3.1.1.5 |
|
A set of dot1QTrunk(1) causes the port specified by ctVlanPortNum
to transmit tagged frames exclusively, and ctVlanPortDiscardFrame
is set to a value of discardUntagged(2). Additionally the specified
port is added to the egress list of all existing VLANS, and all
existing VLANS are enabled as specified by ctVlanStatus. If new
VLANS are established and any port is configured as a dot1QTrunk(1)
then the newly created VLAN will automatically be added to the
egress list (ctVlanEgressList) for the port specified by
ctVlanPortNum. A set of hybrid(2) allows the port to transmit
both tagged and untagged frames. Additionally the specified
port is removed from all VLANS except the the VLAN as specified
by ctVlanPortVID. A set of hybrid(2) will also set
ctVlanPortDiscardFrame to a value of noDiscard(1). A set of
dot1dTrunk(3) causes the port specified by ctVlanPortNum to
transmit untagged frames exclusively, and ctVlanPortDiscardFrame
is set to a value of noDiscard(1). Additionally the specified
port is added to the egress list and the untagged list of all
existing VLANS, and all existing VLANS are enabled as specified
by ctVlanStatus. If new VLANS are established and any port is
configured as a dot1dTrunk(3) then the newly created VLAN will
automatically be added to the egress list (ctVlanEgressList) and
the untagged list (ctVlanEgressUntaggedList) for the port specified
by ctVlanPortNum.
|
| ctVlanPortIngressFiltering |
.1.3.6.1.4.1.52.4.1.2.16.3.1.1.6 |
|
A set of enable(1) causes the forwarding process to discard any frame
received on the port, specified by ctVlanPortNum, that is not a member
of the classified VLANs' egress list, as specified bt ctVlanEgressList.
VLAN classification may be accomplished via the PVID, as specified by
ctVlanPortVID, for untagged frames, or the VLAN Id specified in the
VLAN tag for tagged packets. A set of disable(2) causes the port to
submit all frames to the forwarding process that have not already been
discarded by ctVlanPortDiscardFrame.
|
| ctVlanVID |
.1.3.6.1.4.1.52.4.1.2.16.4.4.1.1 |

A set of this object prior to creating an entry by
setting ctVlanEstablish will fail with a NO-INSTANCE error.
|
| ctVlanStatus |
.1.3.6.1.4.1.52.4.1.2.16.4.4.1.3 |
|
A set with the value of enable(1), enables all associated entries
in ctVlanEgressPorts table for the specified VLAN. A set of
disable(2), disables all ctVlanEgressPorts entries associated with
the specified VLAN. On ports for which the ctVlanVID specifies
the PVID, the operation causes the PVID to be set to the default
PVID value. A set of this object prior to creating an entry by
setting ctVlanEstablish will fail with a NO-INSTANCE error.
|
| ctVlanEstablish |
.1.3.6.1.4.1.52.4.1.2.16.4.4.1.4 |
|
A set of the value create(1), causes an entry to be created in
the ctVlanConfigTable as specified by the instancing information
of ctVlanVID. Additionally, an entry is created in the
ctVlanEgressPortsTable for the specified VLAN. A set of delete(2)
causes the specified entry to be removed from both tables. A read
of this object will always return create(1).
|
| ctVlanIdToFidMapping |
.1.3.6.1.4.1.52.4.1.2.16.4.4.1.5 |
|
The 12 bit Filter Database Identifier (FID) associated with the
configured VLAN as specified by ctVlanVID.
For devices operating in Independent VLAN Learning (IVL) mode, as
specified by a value of ivl(1) for ctVlanLearningMode, each VLAN
will be mapped to a FID value equal to the VLAN Id specified
by ctVlanId.
For devices operating in Shared VLAN Learning (SVL) mode, as specified
by a value of svl(2) for ctVlanLearningMode, all VLANs will be to the
same FID (1). On a device operating in SVL mode, sets to this object
will have no effect.
For devices operating in Shared and Independent VLAN Learning
(SIVL) mode, as specified by a value of svlivl(3) for
ctVlanLearningMode, one or more VLANs can be mapped to each FID. Each
VLAN can only be uniquely mapped to one FID. When more than one VLAN
is mapped to a single FID they will operate together under the SVL mode
of operation. When a single VLAN is mapped to a FID it will operate
under the IVL mode of operation. The default value for this object,
while the device is svlivl(3) mode, will be equal to the VLAN Id
specified by ctVlanId.
|
| ctVlanType |
.1.3.6.1.4.1.52.4.1.2.16.4.4.1.6 |
|
This object indicates the type for this entry.
A value of other(1) indicates that this entry is currently in use
but the conditions under which it will remain so differ from the
following values.
A value of static(2) indicates that this entry has been statically
configured by management, is currently in use and will remain so after
the next reset of the device.
A value of dynamicGvrp(3) indicates that this entry is currently in use
and will remain so until removed by GVRP. There is no static entry for
this VLAN and it will be removed when the last port leaves the VLAN.

|
| ctVlanEgressList |
.1.3.6.1.4.1.52.4.1.2.16.4.5.1.3 |
|
The set of ports to which traffic destined for
the VLAN specified by ctVlanEgressVID
on the device specified by ctVlanEgressPortSlotNum
may be transmitted. Each octet within the value of
this object specifies a set of eight ports, with the
first octet specifying ports 1 through 8, the second
octet specifying ports 9 through 16, etc. Within each
octet, the most significant bit represents the lowest
numbered port, and the least significant bit represents
the highest numbered port. Thus, each port of the VLAN
bridge is represented by a single bit within the value
of this object. If that bit has a value of '1' then
that port is included in the set of ports; the port is
not included if its bit has a value of '0'. A set of '1'
for a port that does not have a '1' for the corresponding
bit in the ctVlanSupportedPortNum will be ignored.
|
| ctVlanEgressUntaggedList |
.1.3.6.1.4.1.52.4.1.2.16.4.5.1.4 |
|
The set of ports to which traffic destined for
the VLAN specified by ctVlanEgressVID
on the device specified by ctVlanEgressPortSlotNum
should be untagged. Each octet within the value of
this object specifies a set of eight ports, with the
first octet specifying ports 1 through 8, the second
octet specifying ports 9 through 16, etc. Within each
octet, the most significant bit represents the lowest
numbered port, and the least significant bit represents
the highest numbered port. Thus, each port of the VLAN
bridge is represented by a single bit within the value
of this object. If that bit has a value of '1' then
that port is included in the set of ports; the port is
not included if its bit has a value of '0'. All egress
ports, as specified by ctVlanEgressList, that do not have
a value of '1' for the corresponding bit in this object
will be tagged. A set of '1' for a port that does not have
a '1' for the corresponding bit in the ctVlanEgressList will
be ignored.
|
| ctVlanProtoEtherType |
.1.3.6.1.4.1.52.4.1.2.16.5.3.1.1 |
|
This object returns the protocol or Ether type that is mapped to
the VLAN specified in it's instancing. This object takes the
value of any valid Ether type(0x0600..0xFFFF).
In addition to the previously mentioned range of Ether types, the
following values hold special meaning:
Value Description DSAP/SSAP/Control
------- --------------- ----------------------
0x100 LLC_IPX1 0xE0E003
0x101 LLC_IPX2 0xFFFF
0x102 LLC_NETBIOS 0xF0F003

|
| ctVlanProtoEstablish |
.1.3.6.1.4.1.52.4.1.2.16.5.3.1.2 |
|
A set of the value create(1), causes an entry to be added to the
ctVlanProtoAssignTable as specified by the instancing information
of ctVlanVID and ctVlanProtoEtherType. This has the result
of mapping the specified protocol or Ether type to a VLAN
for all received untagged traffic on the ports specified by
ctVlanProtoPortList. A set of the value delete(2),
causes the specified entry information to be removed from the table.
A read of this object will always return create(1).
|
| ctVlanProtoPortList |
.1.3.6.1.4.1.52.4.1.2.16.5.3.1.3 |
|
The set of ports on the device, specified by ctVlanVID and
ctVlanProtoEtherType, that will classify received 'untagged'
packets of ctVlanProtoEtherType type, to the VLAN specified
by ctVlanVID. Each octet within the value of this object
specifies a set of eight ports, with the first octet specifying ports 1
through 8, the second octet specifying ports 9 through 16, etc. Within
each octet, the most significant bit represents the lowest numbered
port, and the least significant bit represents the highest numbered
port. Thus, each port on this device is represented by a single bit
within the value of this object. If that bit has a
value of '1' then that port is included in the set of ports; the port
is not included if its bit has a value of '0'. A set of this object
prior to creating an entry by setting ctVlanProtoEstablish will fail
with a NO-INSTANCE error. This object will have an initial value '0'
for each port that is represented.
