11.1 INTERFACE STATISTICS SCREEN FIELDS
The following list describes the Interface Statistics screen fields:
In Octets
This field displays the number of octets (bytes) received by the interface.
In Unicast Pkts
This field displays the number of unicast packets (packets destined for
one specific address) received on the interface.
In Nonucast Pkts
This field displays the number of non-unicast packets (multicast and
broadcast packets; packets destined for more than one address) received
by the interface.
In Discards
This field displays the total number of packets discarded by the interface
due to a lack of available resources.
In Errors
This field displays the total number of errors received on the interface.
The number displayed in the In Errors display field can be composed of
the following errors:
• Out Of Window (OOW) collisions - Collisions caused by a station
on the network violating Carrier Sense and transmitting at will, a
cable failure occurring during the transmission of a packet, or
network propagation delay greater than 51.2
µ
s.
• Cyclical Redundancy Check (CRC) errors - Errors in the 4-byte
CRC field of a packet which ensures that the data received by the
ESXMIM is the same as the data transmitted by the originating
device.
NOTE
For interface 7, the BRIM port, the In Discards field displays
the number of times the ESXMIM had to discard packets - any
number of packets - received on the interface.
