Chapter 11: The Interface Statistics Screen

11.1INTERFACE 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.

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.

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 ∝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.
