Description
Identifies the number of packets that could not be
transmitted because of errors within the packets.
Identifies the number of multicast packets that were
received during the given hour. This is inclusive of
packets with broadcast MAC addresses for protocols
such as ARP, and multicast packets for group-oriented
transmissions, such as IP Multicast.
Multicast packets are packets intended for more than
one Ethernet address.
Identifies the number of unicast packets that were
received during the given hour with a unicast Ethernet
address directly matching that of the specified unit.
Unicast packets are packets intended for only one
Ethernet address.
Identifies the number of packets that were received
during the given hour and discarded due to a lack of
available receive buffers.
Identifies the number of packets that were received
during the given hour that contained errors that
prevented them from being deliverable to a higher-
layer protocol.
Identifies the number of collisions that have occurred
on the Ethernet interface when attempting to transmit
packets since the statistics were last reset.
Note: The Collisions statistic is only applicable in
half-duplex mode.
