- Network
Management ID
A
unique ID assigned by the system for the network management of each
network interface.
- PPA Number
A
unique number assigned to each network interface, distinct from
NMID.
- Description
A
textual string containing information about the interface.
- Type (value)
The type of interface, distinguished according to
the physical/link protocols, immediately below the network layer
in the protocol stack.
Gigabit Ethernet can have one of the following values: ethernet or IEEE
802.3.
- MTU Size
The size of the largest datagram which can be sent/received
on the interface specified in octets. This value can be 1500 or
9000.
- Speed in bits per second
The speed of the card — 1000 Mbps for 1000Base-SX and
10, 100, or 1000 Mbps for 1000Base-T.
- Station Address
The interface address at the protocol layer immediately
below the network layer in the protocol stack. For interfaces which
do not have such an address, such as serial line, this object contains
an octet string of zero length.
- Administration Status
The status of the card. This parameter is set to up(1) and is not configurable. It will have one of the following
values:
up(1) | Ready
to pass packets |
down(2) | Not
operative |
testing(3) | In test
mode |
- Operation Status
The status of the link. This value is the same as
the administration status. If the value is up, the link is operational.
- 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 zero value.
- Inbound Octets
The total number of octets received on the interface, including
framing characters.
- Inbound Unicast Packets
The number of subnetwork-unicast packets delivered to
a high-layer protocol.
- Inbound Non-Unicast Packets
The number of non-unicast (subnetwork-broadcast
or subnetwork-multicast) packets delivered to a higher-layer protocol.
- Inbound Discards
The number of inbound packets that were discarded even
though no errors had been detected, preventing them from being delivered
to a higher-layer protocol. One possible reason for discarding such
a packet could be out of receive buffers.
- Inbound Errors
The number of inbound packets that contained errors,
preventing them from being deliverable to a higher-layer protocol.
- Inbound Unknown Protocols
The number of packets received via the interface
that were discarded because of an unknown or unsupported protocol.
- Outbound Octets
The total number of octets transmitted out of the interface,
including framing characters.
- Outbound Unicast Packets
The total number of packets that higher-level protocols
requested be transmitted to a subnetwork-unicast address, including
those that were discarded or not sent.
- Outbound Non-Unicast Packets
The total number of packets that higher-level protocols
requested be transmitted to a non-unicast (a subnetwork-broadcast
or subnetwork-multicast) address, including those that were discarded
or not sent.
- Outbound Discards
The number of outbound packets that were discarded even
though no errors had been detected to prevent them from being transmitted.
One possible reason for discarding such a packet could be out of
transmit buffers.
- Outbound Errors
The number of outbound packets that could not be transmitted
because of errors.
- Outbound Queue Length
The length of the output packet queue (in packets).
