Use the Interfaces attributes to display performance and identifying information for a specific interface.
Note: It is possible for the value of the Percent Inbound Packets in Error attribute to actually exceed 100%. This is due to the way inbound packets and errors are counted in the Communications Server TCP/IP stack. Many errors are encountered and recorded before the stack can determine how many packets were received, or whether the packets are unicast, multicast, or broadcast. In this case, `the TCP/IP stack records the error, but not the inbound packet. In unusual circumstances, the number of errors recorded might actually exceed the number of inbound packets recorded.
Bandwidth Utilization The total percentage of bandwidth being used during the most recent sample. This value is the total of the Transmit Bandwidth Utilization and the Receive Bandwidth Utilization values. The format is an integer.
Collection Time The time and date of the data sampling. This time is displayed in the following format:
mm/dd/yy hh:mm:ss
Where:
The stored format is a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:
Current State The current operational state of the interface. This value is stored as an integer and displayed as a string. Valid values are:
Description A textual string containing information about the interface. This string includes the name of the manufacturer, the product name, and the version of the interface hardware or software or both. The format is a string up to 255 characters in length.
Inbound Packet Discard Rate The number of packets received that have been discarded, per minute, during the most recent sample. This rate applies to packets that were chosen to be discarded, though no errors had been detected to prevent them from being delivered to a higher-layer protocol. One reason for discarding packets might be to free up buffer space. The format is an integer.
Inbound Packets Discarded The number of packets received that have been discarded during the most recent sample. This number includes packets that were chosen to be discarded, though no errors had been detected to prevent them from being delivered to a higher-layer protocol. One reason for discarding packets might be to free up buffer space. The format is an integer.

Multi/Broadcast Transmit Packet rate The number of packets transmitted to a broadcast or multicast address, per minute, during the most recent time interval. The format is an integer.
Octets Received The number of octets, including framing characters, received since TCP/IP initialization. When the value in the Octets Received field exceeds 1,073,741,823 (1 GB), the number is divided by 1,073,741,824. The quotient is stored in the Octets Received (in GB) field and the remainder is stored in the Octets Received field. This value is an integer.
Octets Received (in GB) The number of octets, including framing characters, received since TCP/IP initialization, divided by 1,073,741,824. When the value in the Octets Received field exceeds 1,073,741,823 (1 GB), the number is divided by 1,073,741,824. The quotient is stored in the Octets Received (in GB) field and the remainder is stored in the Octets Received field. This value is an integer.
Octets Transmitted The number of octets, including framing characters, transmitted out of the interface since TCP/IP initialization. When the value in the Octets Transmitted field exceeds 1,073,741,823 (1 GB), the number is divided by 1,073,741,824. The quotient is stored in the Octets Transmitted (in GB) field and the remainder is stored in the Octets Transmitted field. This value is an integer.
Octets Transmitted (in GB) The number of octets, including framing characters, transmitted out of the interface since TCP/IP initialization, divided by 1,073,741,824. When the value in the Octets Transmitted field exceeds 1,073,741,823 (1 GB), the number is divided by 1,073,741,824. The quotient is stored in the Octets Transmitted (in GB) field and the remainder is stored in the Octets Transmitted field. This value is an integer.
Origin Node The unique identifier for the TCP/IP stack being displayed. The format is a string up to 32 characters in length.
Outbound Packet Discard Rate The number of packets sent that were discarded, per minute, during the most recent sample. This rate applies to packets chosen to be discarded though no errors had been detected to prevent them being delivered to a higher-layer protocol. One reason for discarding packets might be to free up buffer space. The format is an integer.
Outbound Packets Discarded The number of packets sent that were discarded during the most recent sample. This number includes packets chosen to be discarded though no errors had been detected to prevent them being transmitted. One possible reason for discarding such packets might be to free up buffer space. The format is an integer.
Outbound Packets in Error The number of packets sent that were not transmitted, because of errors, during the most recent time interval. The format is an integer.
Percent Inbound Packets in Error The percentage of inbound packets that were not received, during the most recent time interval, because of errors. The format for this value is in the range of 1 to 100%.
Percent Outbound Packets in Error The percentage of packets sent that were not transmitted, because of errors, during the most recent time interval. The format for this value is in the range of 1 to 100%.
Percent Packets Discarded The percentage of total interface packets (both sent and received) that were discarded during the most recent sample. The format for this value is in the range of 1 to 100%.

TCPIP STC Name The TCP/IP job name. The format is a string up to eight characters in length.
Time Entered Current State The time when the interface entered its current operational state. If the current state was entered prior to the most recent re-initialization of the local network management subsystem, then the value of this field is 0 (zero). This time is displayed in the following format:
