SNMP Monitoring 11-7
• In discards
The number of inbound packets to which were chosen to be discarded even they were
deliverable to a higher-layer protocol. One possible reason for discarding such a packet
could be to free up buffer space.
• Out discards
The number of outbound packets to which were chosen to be discarded even they were
deliverable to a higher-layer protocol. One possible reason for discarding such a packet
could be to free up buffer space.
• In errors
The number of inbound packets that contained errors preventing them from being
deliverable to a higher-layer protocol.
• Unknown protocols
The number of packets received via the interface which were discarded because of an
unknown or unsupported protocol.
• Out octets (bytes)
The total number of octets (bytes) transmitted out of the interface, including framing
characters.
• Out unicast packets
The total number of packets that higher-layer protocols requested be transmitted to a sub-
network-unicast address, including those that were discarded or not sent.
• Out non-unicast packets
The total number of packets that higher-layer protocols requested be transmitted to a non-
unicast (i.e. a subnetwork-broadcast or subnetwork-multicast) address, including those that
were discarded or not sent.
• Out errors
The number of outbound packets that contained errors preventing them from being
transmitted via this interface.
• Output queue length
The total number of octets (bytes) waiting to be transmitted via this interface.
