This command accesses the contents of the device IF table. This table provides
information pertaining to the configuration of the various interfaces on the device. Each
interface is assumed to be attached to a subnetwork.
When you choose this command, the MIB-II IF Table appears on the screen:
The following describes the various components on the above screen:
The interface table lists information pertaining to various interfaces (regardless of
their current states) on the device. This table is divided into twelve columns as listed
below. Except for the Index column at the far left, all columns in this table can be
resized by dragging their respective right borders with the mouse left button. The
following describes each column:
The Index column displays the corresponding index number of each entry. Each entry
corresponds to a specific interface on the device.
The Description column corresponds to the IfDescr MIB object of the interface group.
This read-only object displays textual strings containing information about the
interface. These include the name of the device vendor, product name, and the version
of the hardware interface.
The Type column corresponds to the IfType MIB object of the interface group. This
read-only object displays the type of interface according to the physical/link protocol(s)
immediately below the network layer in the protocol stack.
The Mtu column corresponds to the IfMtu MIB object of the interface group. This read-
only object displays the size of the largest datagram that can be sent/received on the
interface (in octets).
The Speed column corresponds to the IfSpeed MIB object of the interface group. This
read-only object displays an estimate of the interface's current bandwidth in bits per
second. If no accurate estimation can be made, this will display the nominal
bandwidth.
The PhysAddress column corresponds to the IfPhysAddress MIB object of the interface
group. This read-only object displays the interface's address at the protocol layer
immediately below the network layer in the protocol stack. For interfaces that do not
have such addresses (for example, serial lines), this displays an octet string of zero
length.
The Admin Status column corresponds to the IfAdminStatus MIB object of the
interface group. This read-only object displays the desired state for the interface.
Testing state indicates that no operational packets can be forwarded on the interface.
