- 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.
- 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 either an ethernet or IEEE 802.3 value.
10/100Base-TX can have either an ethernet-csmacd(6) or iso88023-csmacd(7)
value.
- MTU Size
The size
of the largest datagram which can be sent or 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
Mbit/s for 1000Base-SX. 10, 100, or 1000 Mbit/s for 1000Base-T.
10 Mbit/s or 100 Mbit/s for Fast Ethernet.
- Station Address
The interface address at the protocol layer immediately
below the network layer in the protocol stack. For interfaces that
do not have such an address, such as serial line, this object contains
an octet string of zero length.
- Administration Status (ifAdmin)
Administration Status sets the status
of the card. This parameter may only be set using the Openview Tool.
It may be set to one of these three values:
Table D-1 Administration Status (ifAdmin): Valid Values
up(1) | Allow card
to pass packets |
down(2) | card is
inoperative |
testing(3) | card is
in test mode |
- Operation Status (ifOper)
Operation Status reports the status of the card
if ifAdmin has been set to up(1). If ifAdmin is set to down(2), then ifOper will also be down(2).
Table D-2 Operation Status (ifOper): Valid Values
up(1) | Ready to
pass packets |
down(2) | Not operative
(card is down) |
testing(3) | In test
mode |
- 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 0 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 through
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).
