55.4.1 S (Status)

Displays device status. A green checkmark indicates that the device is active. A red cross indicates that the device is not communicating or is no longer connected to the network. Devices with an inactive status will be removed from the list by a Display Refresh (F5) operation.

55.4.2 MAC Address

Displays the globally unique (Ethernet MAC) address for each discovered device. Ethernet MAC addresses are assigned to devices at manufacture and do not change.

55.4.3 IP Address

Displays the network (IP) address assigned to each device. CobraNet devices initially have an IP address of

0.0.0.0.by default. CobraNet Discovery will assign unique IP addresses to each device when Enable Auto Assignment is checked in the Options dialog (see 55.7). Once an IP address has been assigned to a device, information in the SNMP columns (described below) will be updated.

55.4.4 SNMP columns

Additional columns may be added to the Discovery window by right-clicking on the column header and/or by using the Column Chooser dialog. These columns correspond to SNMP variables. The variables specified are monitored on the CobraNet devices and updated in real time in the Discovery display.

SNMP variables on CobraNet devices are described in detail in the CobraNet Programmer's Reference Manual. All SNMP variables described therein are available for monitoring by entering the specified Object Identifier (OID) in the Add dialog from Column Chooser.

Some of the SNMP variables available for monitoring in a default CobraNet Discovery installation are documented below.

sysDescription

Displays the full name and firmware version of each discovered device.

errorCount

Displays the number of errors that have occurred on the device since the CobraNet Discovery application was started or the display manually reset. Some errors result from normal operation, i.e. re-routing audio, disconnecting/reconnecting Ethernet cables.

errorCode

Reason for the last error reported. errorCode values are documented in the Error Codes section at the back of the CobraNet Programmer's Reference Manual.

ifInErrors

Count of physical errors and packet data detected by the Ethernet receiver. Physical errors are most frequently the result of bad wiring.

Rx1 through Rx4

Bundle receiver status. CobraNet devices typically have four bundle receivers. These four variables show the status of each receiver.

Three metrics are displayed separated by slashes (/). The three values are as follows:

•Bundle number (rxBundle)

•Receive status (rxStatus). Shows 1 if audio data is being received, or 0 if not. The most common reason for not receiving is that there is no transmitter sending that bundle.

•Receive dropouts (rxDropouts). Counts the transitions from receiving to not receiving. Ongoing dropouts may indicate network problems although dropouts also occur when audio is intentionally re-routed.

Tx1 through Tx4

Bundle transmitter status. CobraNet devices typically have four bundle transmitters. These four variables show the status of each transmitter.

Three metrics are displayed separated by slashes (/). The three values are as follows:

•Bundle number (txBundle)

•Number of receivers being served by this transmitter (txReceivers).

•Transmit dropouts (txDropouts). Counts the transitions from transmitting to not transmitting. Ongoing dropouts may indicate network problems although dropouts also occur when audio is intentionally interrupted and re-routed.
