The VLAN Bridge MIB module for managing Virtual Bridged Local Area Networks, as defined by IEEE 802.1Q-2003, including Restricted Vlan Registration defined by IEEE 802.1u-2001 and Vlan Classification defined by IEEE 802.1v-2001. Copyright (C) The Internet Society (2006). This version of this MIB module is part of RFC 4363; See the RFC itself for full legal notices.

The version number of IEEE 802.1Q that this device supports. Enumeration: 'version1': 1.

The maximum IEEE 802.1Q VLAN-ID that this device supports.

The maximum number of IEEE 802.1Q VLANs that this device supports.

The current number of IEEE 802.1Q VLANs that are configured in this device.

The administrative status requested by management for GVRP. The value enabled(1) indicates that GVRP should be enabled on this device, on all ports for which it has not been specifically disabled. When disabled(2), GVRP is disabled on all ports, and all GVRP packets will be forwarded transparently. This object affects all GVRP Applicant and Registrar state machines. A transition from disabled(2) to enabled(1) will cause a reset of all GVRP state machines on all ports. The value of this object MUST be retained across reinitializations of the management system.

A table that contains configuration and control information for each Filtering Database currently operating on this device. Entries in this table appear automatically when VLANs are assigned FDB IDs in the dot1qVlanCurrentTable.

Information about a specific Filtering Database.

The identity of this Filtering Database.

The current number of dynamic entries in this Filtering Database.

A table that contains information about unicast entries for which the device has forwarding and/or filtering information. This information is used by the transparent bridging function in determining how to propagate a received frame.

Information about a specific unicast MAC address for which the device has some forwarding and/or filtering information.

A unicast MAC address for which the device has forwarding and/or filtering information.

Either the value '0', or the port number of the port on which a frame having a source address equal to the value of the corresponding instance of dot1qTpFdbAddress has been seen. A value of '0' indicates that the port number has not been learned but that the device does have some forwarding/filtering information about this address (e.g., in the dot1qStaticUnicastTable). Implementors are encouraged to assign the port value to this object whenever it is learned, even for addresses for which the corresponding value of dot1qTpFdbStatus is not learned(3).

The status of this entry. The meanings of the values are: other(1) - none of the following. This may include the case where some other MIB object (not the corresponding instance of dot1qTpFdbPort, nor an entry in the dot1qStaticUnicastTable) is being used to determine if and how frames addressed to the value of the corresponding instance of dot1qTpFdbAddress are being forwarded. invalid(2) - this entry is no longer valid (e.g., it was learned but has since aged out), but has not yet been flushed from the table. learned(3) - the value of the corresponding instance of dot1qTpFdbPort was learned and is being used. self(4) - the value of the corresponding instance of dot1qTpFdbAddress represents one of the device's addresses. The corresponding instance of dot1qTpFdbPort indicates which of the device's ports has this address. mgmt(5) - the value of the corresponding instance of dot1qTpFdbAddress is also the value of an existing instance of dot1qStaticAddress. Enumeration: 'learned': 3, 'other': 1, 'self': 4, 'invalid': 2, 'mgmt': 5.

A table containing filtering information for VLANs configured into the bridge by (local or network) management, or learned dynamically, specifying the set of ports to which frames received on a VLAN for this FDB and containing a specific Group destination address are allowed to be forwarded.

Filtering information configured into the bridge by management, or learned dynamically, specifying the set of ports to which frames received on a VLAN and containing a specific Group destination address are allowed to be forwarded. The subset of these ports learned dynamically is also provided.

The destination Group MAC address in a frame to which this entry's filtering information applies.

The complete set of ports, in this VLAN, to which frames destined for this Group MAC address are currently being explicitly forwarded. This does not include ports for which this address is only implicitly forwarded, in the dot1qForwardAllPorts list.

The subset of ports in dot1qTpGroupEgressPorts that were learned by GMRP or some other dynamic mechanism, in this Filtering database.

A table containing forwarding information for each VLAN, specifying the set of ports to which forwarding of all multicasts applies, configured statically by management or dynamically by GMRP. An entry appears in this table for all VLANs that are currently instantiated.

Forwarding information for a VLAN, specifying the set of ports to which all multicasts should be forwarded, configured statically by management or dynamically by GMRP.

The complete set of ports in this VLAN to which all multicast group-addressed frames are to be forwarded. This includes ports for which this need has been determined dynamically by GMRP, or configured statically by management.

The set of ports configured by management in this VLAN to which all multicast group-addressed frames are to be forwarded. Ports entered in this list will also appear in the complete set shown by dot1qForwardAllPorts. This value will be restored after the device is reset. This only applies to ports that are members of the VLAN, defined by dot1qVlanCurrentEgressPorts. A port may not be added in this set if it is already a member of the set of ports in dot1qForwardAllForbiddenPorts. The default value is a string of ones of appropriate length, to indicate the standard behaviour of using basic filtering services, i.e., forward all multicasts to all ports. The value of this object MUST be retained across reinitializations of the management system.

The set of ports configured by management in this VLAN for which the Service Requirement attribute Forward All Multicast Groups may not be dynamically registered by GMRP. This value will be restored after the device is reset. A port may not be added in this set if it is already a member of the set of ports in dot1qForwardAllStaticPorts. The default value is a string of zeros of appropriate length. The value of this object MUST be retained across reinitializations of the management system.

A table containing forwarding information for each VLAN, specifying the set of ports to which forwarding of multicast group-addressed frames for which no more specific forwarding information applies. This is configured statically by management and determined dynamically by GMRP. An entry appears in this table for all VLANs that are currently instantiated.

The set of ports configured by management, in this VLAN, to which multicast group-addressed frames for which there is no more specific forwarding information are to be forwarded. Ports entered in this list will also appear in the complete set shown by dot1qForwardUnregisteredPorts. This value will be restored after the device is reset. A port may not be added in this set if it is already a member of the set of ports in dot1qForwardUnregisteredForbiddenPorts. The default value is a string of zeros of appropriate length, although this has no effect with the default value of dot1qForwardAllStaticPorts. The value of this object MUST be retained across reinitializations of the management system.

The set of ports configured by management in this VLAN for which the Service Requirement attribute Forward Unregistered Multicast Groups may not be dynamically registered by GMRP. This value will be restored after the device is reset. A port may not be added in this set if it is already a member of the set of ports in dot1qForwardUnregisteredStaticPorts. The default value is a string of zeros of appropriate length. The value of this object MUST be retained across reinitializations of the management system.

A table containing filtering information for Unicast MAC addresses for each Filtering Database, configured into the device by (local or network) management specifying the set of ports to which frames received from specific ports and containing specific unicast destination addresses are allowed to be forwarded. A value of zero in this table (as the port number from which frames with a specific destination address are received) is used to specify all ports for which there is no specific entry in this table for that particular destination address. Entries are valid for unicast addresses only.

Filtering information configured into the device by (local or network) management specifying the set of ports to which frames received from a specific port and containing a specific unicast destination address are allowed to be forwarded.

The destination MAC address in a frame to which this entry's filtering information applies. This object must take the value of a unicast address.

Either the value '0' or the port number of the port from which a frame must be received in order for this entry's filtering information to apply. A value of zero indicates that this entry applies on all ports of the device for which there is no other applicable entry.

The set of ports for which a frame with a specific unicast address will be flooded in the event that it has not been learned. It also specifies the set of ports on which a specific unicast address may be dynamically learned. The dot1qTpFdbTable will have an equivalent entry with a dot1qTpFdbPort value of '0' until this address has been learned, at which point it will be updated with the port the address has been seen on. This only applies to ports that are members of the VLAN, defined by dot1qVlanCurrentEgressPorts. The default value of this object is a string of ones of appropriate length. The value of this object MUST be retained across reinitializations of the management system.

This object indicates the status of this entry. other(1) - this entry is currently in use, but the conditions under which it will remain so differ from the following values. invalid(2) - writing this value to the object removes the corresponding entry. permanent(3) - this entry is currently in use and will remain so after the next reset of the bridge. deleteOnReset(4) - this entry is currently in use and will remain so until the next reset of the bridge. deleteOnTimeout(5) - this entry is currently in use and will remain so until it is aged out.

The set of ports to which frames received from a specific port and destined for a specific Multicast or Broadcast MAC address must be forwarded, regardless of any dynamic information, e.g., from GMRP. A port may not be added in this set if it is already a member of the set of ports in dot1qStaticMulticastForbiddenEgressPorts. The default value of this object is a string of ones of appropriate length. The value of this object MUST be retained across reinitializations of the management system.

The set of ports to which frames received from a specific port and destined for a specific Multicast or Broadcast MAC address must not be forwarded, regardless of any dynamic information, e.g., from GMRP. A port may not be added in this set if it is already a member of the set of ports in dot1qStaticMulticastStaticEgressPorts.

Information for a VLAN configured into the device by (local or network) management, or dynamically created as a result of GVRP requests received.

A TimeFilter for this entry. See the TimeFilter textual convention to see how this works.

The VLAN-ID or other identifier referring to this VLAN.

The Filtering Database used by this VLAN. This is one of the dot1qFdbId values in the dot1qFdbTable. This value is allocated automatically by the device whenever the VLAN is created: either dynamically by GVRP, or by management, in dot1qVlanStaticTable. Allocation of this value follows the learning constraints defined for this VLAN in dot1qLearningConstraintsTable.

The set of ports that are transmitting traffic for this VLAN as either tagged or untagged frames.

The set of ports that are transmitting traffic for this VLAN as untagged frames.

This object indicates the status of this entry. other(1) - this entry is currently in use, but the conditions under which it will remain so differ from the following values. permanent(2) - this entry, corresponding to an entry in dot1qVlanStaticTable, is currently in use and will remain so after the next reset of the device. The port lists for this entry include ports from the equivalent dot1qVlanStaticTable entry and ports learned dynamically. dynamicGvrp(3) - 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. Enumeration: 'permanent': 2, 'other': 1, 'dynamicGvrp': 3.

The value of sysUpTime when this VLAN was created.

A table containing static configuration information for each VLAN configured into the device by (local or network) management. All entries are permanent and will be restored after the device is reset.

Static information for a VLAN configured into the device by (local or network) management.

An administratively assigned string, which may be used to identify the VLAN.

The set of ports that are permanently assigned to the egress list for this VLAN by management. Changes to a bit in this object affect the per-port, per-VLAN Registrar control for Registration Fixed for the relevant GVRP state machine on each port. A port may not be added in this set if it is already a member of the set of ports in dot1qVlanForbiddenEgressPorts. The default value of this object is a string of zeros of appropriate length, indicating not fixed.

The set of ports that are prohibited by management from being included in the egress list for this VLAN. Changes to this object that cause a port to be included or excluded affect the per-port, per-VLAN Registrar control for Registration Forbidden for the relevant GVRP state machine on each port. A port may not be added in this set if it is already a member of the set of ports in dot1qVlanStaticEgressPorts. The default value of this object is a string of zeros of appropriate length, excluding all ports from the forbidden set.

The set of ports that should transmit egress packets for this VLAN as untagged. The default value of this object for the default VLAN (dot1qVlanIndex = 1) is a string of appropriate length including all ports. There is no specified default for other VLANs. If a device agent cannot support the set of ports being set, then it will reject the set operation with an error. For example, a manager might attempt to set more than one VLAN to be untagged on egress where the device does not support this IEEE 802.1Q option.

This object indicates the status of this entry.

The next available value for dot1qVlanIndex of a local VLAN entry in dot1qVlanStaticTable. This will report values >=4096 if a new Local VLAN may be created or else the value 0 if this is not possible. A row creation operation in this table for an entry with a local VlanIndex value may fail if the current value of this object is not used as the index. Even if the value read is used, there is no guarantee that it will still be the valid index when the create operation is attempted; another manager may have already got in during the intervening time interval. In this case, dot1qNextFreeLocalVlanIndex should be re-read and the creation re-tried with the new value. This value will automatically change when the current value is used to create a new row.

A table containing per-port control and status information for VLAN configuration in the device.

Information controlling VLAN configuration for a port on the device. This is indexed by dot1dBasePort.

The PVID, the VLAN-ID assigned to untagged frames or Priority-Tagged frames received on this port. The value of this object MUST be retained across reinitializations of the management system.

When this is admitOnlyVlanTagged(2), the device will discard untagged frames or Priority-Tagged frames received on this port. When admitAll(1), untagged frames or Priority-Tagged frames received on this port will be accepted and assigned to a VID based on the PVID and VID Set for this port. This control does not affect VLAN-independent Bridge Protocol Data Unit (BPDU) frames, such as GVRP and Spanning Tree Protocol (STP). It does affect VLAN- dependent BPDU frames, such as GMRP. The value of this object MUST be retained across reinitializations of the management system. Enumeration: 'admitAll': 1, 'admitOnlyVlanTagged': 2.

When this is true(1), the device will discard incoming frames for VLANs that do not include this Port in its Member set. When false(2), the port will accept all incoming frames. This control does not affect VLAN-independent BPDU frames, such as GVRP and STP. It does affect VLAN- dependent BPDU frames, such as GMRP. The value of this object MUST be retained across reinitializations of the management system.

The state of GVRP operation on this port. The value enabled(1) indicates that GVRP is enabled on this port, as long as dot1qGvrpStatus is also enabled for this device. When disabled(2) but dot1qGvrpStatus is still enabled for the device, GVRP is disabled on this port: any GVRP packets received will be silently discarded, and no GVRP registrations will be propagated from other ports. This object affects all GVRP Applicant and Registrar state machines on this port. A transition from disabled(2) to enabled(1) will cause a reset of all GVRP state machines on this port. The value of this object MUST be retained across reinitializations of the management system.

The total number of failed GVRP registrations, for any reason, on this port.

The Source MAC Address of the last GVRP message received on this port.

The state of Restricted VLAN Registration on this port. If the value of this control is true(1), then creation of a new dynamic VLAN entry is permitted only if there is a Static VLAN Registration Entry for the VLAN concerned, in which the Registrar Administrative Control value for this port is Normal Registration. The value of this object MUST be retained across reinitializations of the management system.

A table containing per-port, per-VLAN statistics for traffic received. Separate objects are provided for both the most-significant and least-significant bits of statistics counters for ports that are associated with this transparent bridge. The most-significant bit objects are only required on high-capacity interfaces, as defined in the conformance clauses for these objects. This mechanism is provided as a way to read 64-bit counters for agents that support only SNMPv1. Note that the reporting of most-significant and least- significant counter bits separately runs the risk of missing an overflow of the lower bits in the interval between sampling. The manager must be aware of this possibility, even within the same varbindlist, when interpreting the results of a request or asynchronous notification.

Traffic statistics for a VLAN on an interface.

The number of valid frames received by this port from its segment that were classified as belonging to this VLAN. Note that a frame received on this port is counted by this object if and only if it is for a protocol being processed by the local forwarding process for this VLAN.

The compliance statement for device support of Virtual LAN Bridge services. RFC2674 was silent about the expected persistence of the read-write objects in this MIB module. Applications MUST NOT assume that the values of the read-write objects are persistent across reinitializations of the management system and MUST NOT assume that the values are not persistent across reinitializations of the management system.

The compliance statement for device support of Virtual LAN Bridge services. This document clarifies the persistence requirements for the read-write objects in this MIB module. All implementations claiming compliance to qBridgeCompliance2 MUST retain the values of those read-write objects that specify this requirement.
