Interface {#IFNAME}({#IFALIAS}): Inbound packets with errors | MIB: IF-MIB For packet-oriented interfaces, the number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. For character-oriented or fixed-length interfaces, the number of inbound transmission units that contained errors preventing them from being deliverable to a higher-layer protocol.

Interface {#IFNAME}({#IFALIAS}): Outbound packets discarded | MIB: IF-MIB The number of outbound 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. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. |

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 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. |
