system reboot.
Select the required port. The statistics displayed are indicated in the following figure and
table.
Parameter Description
Interfaces Group
In Octets The total number of octets received on the interface, including
framing characters.
In Unicast Pkts. The number of subnetwork-unicast packets delivered to a
higher-layer protocol.
In Non-Unicast
Pkts.
The number of non-unicast (that is, subnetwork- broadcast or
subnetwork-multicast) packets delivered to a higher-layer protocol.
In Discards 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.
In Errors The number of inbound packets that contained errors preventing
them from being deliverable to a higher-layer protocol.
Alignment Errors The number of alignm ent errors (missynchronized data packets).
