| Interface {#IFNAME}({#IFALIAS}): Inbound packets discarded | MIB: IF-MIB The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.

| Interface {#IFNAME}({#IFALIAS}): Speed | MIB: IF-MIB An estimate of the interface's current bandwidth in units of 1,000,000 bits per second. If this object reports a value of n' then the speed of the interface is somewhere in the range of n-500,000' to`n+499,999'. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth. For a sub-layer which has no concept of bandwidth, this object should be zero. | SNMP_AGENT | 5m | net.if.speed[ifHighSpeed.{#SNMPINDEX}] |
| Interface {#IFNAME}({#IFALIAS}): Operational status | MIB: IF-MIB The current operational state of the interface. - The testing(3) state indicates that no operational packet scan be passed - If ifAdminStatus is down(2) then ifOperStatus should be down(2) - If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic - It should change todormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection) - It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state - It should remain in the notPresent(6) state if the interface has missing(typically, hardware) components. | SNMP_AGENT | - | net.if.status[ifOperStatus.{#SNMPINDEX}] |

| Interface {#IFNAME}({#IFALIAS}): Duplex status | MIB: EtherLike-MIB The current mode of operation of the MAC entity. 'unknown' indicates that the current duplex mode could not be determined. Management control of the duplex mode is accomplished through the MAU MIB. When an interface does not support autonegotiation, or when autonegotiation is not enabled, the duplex mode is controlled using ifMauDefaultType. When autonegotiation is supported and enabled, duplex mode is controlled using ifMauAutoNegAdvertisedBits. In either case, the currently operating duplex mode is reflected both in this object and in ifMauType. Note that this object provides redundant information with ifMauType. Normally, redundant objects are discouraged. However, in this instance, it allows a management application to determine the duplex status of an interface without having to know every possible value of ifMauType. This was felt to be sufficiently valuable to justify the redundancy. Reference: [IEEE 802.3 Std.], 30.3.1.1.32,aDuplexStatus. | SNMP_AGENT | - | net.if.duplex[dot3StatsDuplexStatus.{#SNMPINDEX}] |
