- Click Print to print the contents of the dialog box.
- Click Help to access online help.

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.

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.

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.

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 "0".

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.
