Description: Manages optical channel (OCH) configuration and performance for DCP optical networking.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DCP-OCH-MIB?

This is the enterprise-specific DCP OCH (Optical Channel) MIB from Smartoptics, covering the optical channel layer of the vendor's DCP DWDM transport platform. It exposes configuration and utilization data for optical channel groups and individual channels through dcpOchGeneralTable and dcpOchTable, including channel spacing, maximum supported channels, and how many channels are actively configured and in use. For monitoring purposes it lets operators track channel utilization (dcpOchGeneralUtilization) against capacity (dcpOchGeneralMaxChannels), essentially a capacity/performance metric analogous to tracking how full a DWDM line system's optical spectrum is. This is a standalone enterprise MIB, generally used alongside DCP-INTERFACE-MIB for a complete picture of optical port-level and channel-level status on the same platform. It is deployed in metro/long-haul optical transport networks to plan capacity and detect when a DWDM multiplexer port is nearing its channel limit, and engineers can download the DCP-OCH-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DCP-OCH-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An engineer would poll dcpOchGeneralTable per port (dcpOchGeneralPortName) to compare dcpOchGeneralActiveChannels and dcpOchGeneralConfiguredChannels against dcpOchGeneralMaxChannels, revealing how much optical spectrum capacity remains on that mux port. Rising dcpOchGeneralUtilization approaching 100% signals the port is nearing full channel capacity and additional wavelengths cannot be added without new hardware. dcpOchTable/dcpOchEntry, indexed by dcpOchIndex, would then be walked to inspect the state of individual channels within that group.

How to Use in IPNetwork Monitor

Example using dcpOchGeneralUtilization OID:

Select a Smartoptics DCP optical transport platform (optical channel layer) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type dcpOchGeneralUtilization into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of channels used in the system in units of %. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
