extremeVlanGlobalMappingTable This table lists VLAN interfaces that are globally identified.  A single entry exists in this list for
                    each VLAN interface in the system that is bound to
                    a global identifier.

extremeVlanGlobalMappingEntry An individual VLAN interface global mapping entry. Entries in this table are created by setting the extremeVlanIfGlobalIdentifier object in the extremeVlanIfTable to a non-zero value.

extremeVlanGlobalMappingIdentifier An index into the extremeVlanGlobalMappingTable and an administratively assigned global VLAN identifier.  The value of this object globally identifies the VLAN interface. For VLAN interfaces, on different network devices, which are part of the same globally identified VLAN, the value of this object will be the same.

extremeVlanGlobalMappingIfIndex The value of extremeVlanIfIndex for the VLAN interface in the extremeVlanIfTable, which is bound to the global identifier specified by this entry.

extremeVlanIfTable This table lists VLAN interfaces that exist within a device.  A single entry exists in this list for each VLAN interface in the system.  A VLAN interface may be created, destroyed and/or mapped to a globally identified vlan.

extremeVlanIfEntry An individual VLAN interface entry.  When an NMS wishes to create a new entry in this table, it must obtain a non-zero index from the extremeNextAvailableVirtIfIndex object.  Row creation in this table will fail if the chosen index value does not match the current value returned from the extremeNextAvailableVirtIfIndex object.

extremeVlanIfIndex The index value of this row and the vlan's ifIndex in the ifTable. The NMS obtains the index value for this row by reading the extremeNextAvailableVirtIfIndex object.

extremeVlanIfDescr This is a description of the VLAN interface.

extremeVlanIfType The VLAN interface type.

extremeVlanIfGlobalIdentifier An administratively assigned global VLAN identifier.  For VLAN interfaces, on different network devices, which are part of the same globally identified VLAN, the value of this object will be the same.

The binding between a global identifier and a VLAN interface can be created or removed.  To create a binding an NMS must write a non-zero value to this object.  To delete a binding, the NMS must write a zero to this object. The value 1 is reserved for the default VLAN and this cannot be deleted or re-assigned.

extremeVlanIfStatus The status column for this VLAN interface. This OBJECT can be set to:

active(1)
createAndGo(4)
createAndWait(5)
destroy(6)

      The following values may be read:
active(1)
notInService(2) notReady(3).

Setting this object to createAndGo(4) causes the agent to attempt to create and commit the row based on the contents of the objects in the row.  If all necessary information is present in the row and the values are acceptible to the agent, the agent will change the status to active(1).  If any of the necessary objects are not available, the agent will reject the creation request.

Setting this object to createAndWait(5) causes a row in this table to be created.  The agent sets the status to notInService(2) if all of the information is present in the row and the values are acceptable to the agent; otherwise, the agent sets the status to notReady(3).

Setting this object to active(1) is only valid when the current status is active(1) or notInService(2).

When the state of the row transitions is set to active(1), the agent creates the corresponding row in the ifTable.

Setting this object to destroy(6) will remove the
      corresponding VLAN interface, remove the entry in this
      table, and the corresponding entries in the
      extremeVlanGlobalMappingTable and the ifTable.

In order for a set of this object to destroy(6) to succeed, all dependencies on this row must have been removed. These will include any stacking dependencies in the ifStackTable
      and any protocol specific tables dependencies.

extremeVlanIfIgnoreStpFlag Enable/disable STP for this VLAN interface. Setting this object to true will cause the ports on this VLAN to ignore STP BPDUs. When a vlan is first created, the Default value is FALSE, which means that the VLAN uses STP port information

extremeVlanIfIgnoreBpduFlag Setting this object to true causes this VLAN's BPDU's to be ignored by the Spanning Tree process. This can be used to keep the root bridge within one's own network when external switches also fall within the same Spanning Tree Domain. When a vlan is first created, the Default value is FALSE.

extremeVlanIfLoopbackModeFlag Setting this object to true causes loopback mode to be enabled on this VLAN.

extremeVlanIfVlanId The VLAN ID of this VLAN.

extremeVlanEncapsIfTable This table lists VLAN encapsulation interfaces that exist within a device.  A single entry exists in this list for each VLAN encapsulation interface in the system.  A VLAN encapsulation interface may be created or destroyed.

extremeVlanEncapsIfEntry An individual VLAN encapsulation interface entry. When an NMS wishes to create a new entry in this table, it must obtain a non-zero index from the extremeNextAvailableVirtIfIndex object.  Row creation in this table will fail if the chosen index value does not match the current value returned from the extremeNextAvailableVirtIfIndex object.

extremeVlanEncapsIfIndex The index value of this row and the encapsulation interface's ifIndex in the ifTable.  The NMS obtains the index value used for creating a row in this table by reading the extremeNextAvailableVirtIfIndex object.

extremeVlanEncapsIfType The encapsulation algorithm used when encapsulating packets transmitted, or de-encapsulating packets received through this interface.

extremeVlanEncapsIfTag The tag used when encapsulating packets transmitted, or de-encapsulating packets received through this interface.

extremeVlanEncapsIfStatus The row status for this VLAN encapsulation interface.

This OBJECT can be set to:

active(1) createAndGo(4) createAndWait(5) destroy(6)

The following values may be read: active(1) notReady(3).

In order for a row to become active, the NMS must set extremeVlanEncapsIfTagType and extremeVlanEncapsIfTag to some valid and consistent values.

Setting this object to createAndGo(4) causes the agent to attempt to create and commit the row based on the contents of the objects in the row. If all necessary information is present in the row, the agent will create the row and change the status to active(1).  If any of the necessary objects are not available, or specify an invalid configuration, the row will not be created and the agent will return an appropriate error.

Setting this object to createAndWait(5) causes a row in in this table to be created.  If all necessary objects in the row have been assigned values and specify a valid configuration, the status of the row will be set to notInService(2); otherwise, the status will be set to notReady(3).

This object may only be set to createAndGo(4) or createAndWait(5) if it does not exist.

Setting this object to active(1) when the status is notInService(2) causes the agent to commit the row.  Setting this object to active(1) when its value is already active(1) is a no-op.

Setting this object to destroy(6) will remove the corresponding VLAN encapsulation interface, remove the entry in this table, and remove the corresponding entry in the ifTable.

In order for a set of this object to destroy(6) to succeed, all dependencies on this row must have been removed.  These will include any references to this interface in the ifStackTable.

extremeNextAvailableVirtIfIndex The value of the next available virtual ifIndex.  This object is used by an NMS to select an index value for row-creation in tables indexed by ifIndex.  The current value of this object is changed to a new value when the current value is written to an agent's table, that is indexed by ifIndex.  Row creation using the current value of this object, allocates a virtual ifIndex.  Note the following:

1. A newly created row does not have to be active(1)
  for the agent to allocate the virtual ifIndex.

2. Race conditions between multiple NMS's end when
  a row is created.  Rows are deemed created when
  a setRequest is successfully committed (i.e.
  the errorStats is noError(0)).

3.  An agent that exhausts its supply of virual
  ifIndex values returns zero as the value of this
  object. This can be used by an NMS as an indication
  to deleted unused rows and reboot the device.

extremeVlanIpTable A list of IP VLAN interface information entries.  Entries in this table are related to entries in the extremeVlanIfTable by using the same index.

extremeVlanIpEntry A extremeVlanIpEntry contains layer 3 information about a particular IP VLAN interface.

extremeVlanIpNetAddress The IP network number for the IP VLAN interface defined in the extremeVlanIfTable identified with the same index.

extremeVlanIpNetMask The IP network mask corresponding to the IP Network address defined by extremeVlanIpIpNetAddress.

extremeVlanIpStatus The status column for this IP VLAN entry. This object can be set to:
           active(1)
createAndGo(4)
           destroy(6)

          The following values may be read:
           active(1)

Setting this object to active(1) or createAndGo(4) causes
             the agent to attempt to create and commit the row based on
the contents of the objects in the row.  If all necessary information is present in the row and the values are acceptible to the agent, the agent will change the status to active(1).  If any of the necessary objects are not available, the agent will reject the row creation request.

Setting this object to createAndWait(5) is not supported.

When the status changes to active(1), the agent applies the IP parmeters to the IP VLAN interface identified by the corresponding value of the extremeVlanIpIndex object.

Setting this object to destroy(6) will remove the IP parmeters from the IP VLAN interface and remove the entry from this table.

extremeVlanIpForwardingState Indicates whether the IP Forwarding  on this Vlan is Enable or not. A true value indicates that the Vlan is Enable.

extremeVlanProtocolTable Table of defined combinations of protocol IDs that make up one protocol definition name. All members of one protocol definition share the same extremeVlanProtocolIndex.

The value any(1) is used to indicate a wildcard and matches all encapsulations and protocol IDs that are not explicitly mentioned in this table. Entries of type any(1) may not be created. The value none(5) is used to indicate that no protocol IDs match this entry. A value of none(5) may not be set by a manager.

extremeVlanProtocolId The protocol ID: for entries of type ethertype(2) or llcSnapEthertype(4) this represents a 16-bit protocol ID. For entries of type llc(3) it represents a concatenation of LLC DSAP+SSAP in network byte order. This value is not valid for extremeVlanProtocolDllEncapsType values of any(1) or none(5).

extremeVlanProtocolStatus The row status variable, used according to row installation and removal conventions.
