The following information is displayed:


Name (ifName)

Textual name of the interface.


Description (ifDescr)

Textual description of the physical entity. This object contains a string which identifies the manufacturer name, the product name, and the interface hardware/software version.


Entity Description (entPhysicalDescr)

Textual description of this physical entity. This object should identify the manufacturer of the physical entity and be set to a distinct value for each version or model of the physical entity.


Entity Vendor Type (entPhysicalVendorType)

Vendor-specific hardware type of the physical entity.


Index (ifIndex)

A unique value, greater than zero, for each interface.


Speed (ifSpeed)

An estimate of the interface's current bandwidth, measured in bits per second.

Note the following:


Speed

An estimate of the interface's current bandwidth, measured in bits per second.

Note the following:


Duplex Status (dot3StatsDuplexStatus)

Current mode of operation of the MAC entity. There are three possible values: unknown(1), halfDuplex(2), and fullDuplex(3). The value unknown(1) indicates that the current duplex mode cannot be determined.

Note the following:


Duplex

Current mode of operation of the MAC entity. There are two possible values: Half and Full.

Note the following:


Auto Negotiation (ifMauAutoNegAdminStatus)

When set to enabled, the interface with auto-negotiation signaling capability is enabled. When set to disabled, an IEEE 802.3 MAU enters the state indicated by the value of ifMauDefaultType.


Mtu (ifMtu)

The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that transmit network datagrams, this is the size of the largest network datagram that can be sent on the interface.


Physical Address (ifPhysAddress)

Address of the interface at its protocol sublayer. The media-specific MIB on the interface must define the bit and byte ordering and format of the value contained by this object.


Admin Status (ifAdminStatus)

Chosen state for the interface.

Note: For dual port ATM cards (Ws-X 5157, 5158, 5167, 5168, 5156, 5166, 5161, 5162), the cadpStatAdminActivePhy MIB variable is used to perform an active physical switch over.


Operational Status (ifOperStatus)

Current operational state of the interface.


Keep Alive Enabled (cieIfKeepAliveEnabled)

A small, Layer 2 message that is transmitted by a network device to let directly-connected network devices know of its presence.


Last Change (ifLastChange)

Value of sysUpTime when the interface entered its current operational state. If the current state was entered prior to the last reinitialization of the local network management subsystem, then this object contains a value of zero.


State Change Reason (cieIfStateChangeReason)

Textual string which describes the cause of the last state change of the interface.

Examples of the values this object can take are:


Interface Reset Count (cieIfResetCount)

Number of times the interface was internally reset and brought up. Some of the actions which can cause this counter to increment are:

Discontinuities in the value of this variable can occur at reinitialization of the management system, and at other times as indicated by the values of cieIfInterfaceDiscontinuityTime.


Carrier Signal Transition Count (cieIfCarrierTransitionCount)

Number of times the interface saw the carrier signal transition.

For example, if a T1 line is unplugged, then the framer will detect the loss of signal (LOS) on the line and count it as a transition.

Discontinuities in the value of this object can occur at reinitialization of the management system, and at other times as indicated by the values of cieIfInterfaceDiscontinuityTime.


Up/Down Traps (ifLinkUpDownTrapEnable)

Indicates whether a trap is sent to the addresses in the Trap Receiver table every time the port state changes from up to down.


Aggregation Protocol (clagAggProtocolType)

Aggregation protocol type for this interface. If an aggregation protocol is assigned to any of the ports in a group, then the aggregation protocol is applied to all the ports in that group (a group is a collection of ports which belong to a module or system). On some platforms, the aggregation protocol type can be assigned per aggregator.


Local Description (ifAlias)

Alias for the interface.


VLANID (vmVlan)

VLAN ID for the interface.

The VLAN id of the VLAN the port is assigned to when vmVlanType is set to static or dynamic. This object is not instantiated if not applicable.

The value may be 0 if the port is not assigned to a VLAN.

If vmVlanType is static, the port is always assigned to a VLAN and the object may not be set to 0.

If vmVlanType is dynamic the object's value is 0 if the port is currently not assigned to a VLAN. In addition, the object may be set to 0 only


VLAN Name (vtpVlanName)

VLAN Name for the interface.

The name of this VLAN. This name is used as the ELAN-name for an ATM LAN-Emulation segment of this VLAN


Voice VLAN Id (vmVoiceVlanId)

The Voice VLAN ID (VVID) to which this port belongs. Valid values range from zero to 4096, as described below:


MAC Addr Learnt Notification enabled (cmnMacAddrLearntEnable)

When this object is set to true(1), this interface is enabled to send a cmnMacChangedNotification each time it learns of a new MAC address.

Note: This object is available only when the value of cmnGlobalFeatureEnabled is true(1).


MAC Addr Removed Notification enabled (cmnMacAddrRemovedEnable)

When this object is set to true(1), this interface is enabled to send a cmnMacChangedNotification each time a previously learned MAC address is removed from the forwarding table.

Note: This object is available only when the value of cmnGlobalFeatureEnabled is true(1).
