11-6 SNMP Monitoring
• Description
A textual string containing information about the interface. This string should include the
name of the manufacturer, the product name, and the version of the hardware interface.
• MIB specific definator
A reference to MIB definitions specific to the particular media being used to realize the
interface. For example, if the interface is being realized by an Ethernet, then the value of this
object refers to a document defining objects specific to the Ethernet. If this information is not
present, its value will be set to 0.
• Physical Address
The interface's address at the protocol layer immediately below the network layer in the
protocol stack. For interfaces which do not have such an address (e.g., a serial line), this
object should contain an octet string of zero length.
• Last Change
The value of sysUpTime at the time 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.
• Operational Status
The state of the interface. The testing state indicates that no operational packets can be
passed. Up - ready to pass packets; Down - cannot pass packets; testing - in some test
mode.
• Admin Status
The desired state of the interface. The testing state indicates that no operational packets can
be passed.
• Speed
An estimate of the interface's current bandwidth in bits per second. For interfaces which do
not vary in bandwidth or whose bandwidth can't be accurately estimated, this object should
contain the nominal bandwidth.
• Max packet size
The size of the largest datagram which can be sent/received on the interface, specified in
octets. For interfaces used for transmitting network datagrams, this is the size of the largest
network datagram that can be sent on the interface.
• In octets (bytes)
The total number of octets (bytes) received on the interface, including framing characters.
• In unicast packets
The number of subnetwork-unicast packets delivered to a higher-layer protocol.
• In non-unicast packets
The number of non-unicast (i.e., subnetwork-broadcast or subnetwork-multicast) packets
delivered to a higher-layer protocol.
