Description: Manages Spatial Reuse Protocol (SRP/DPT) ring interfaces and topology discovery on Cisco dynamic packet transport rings.

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 CISCO-SRP-MIB?

CISCO-SRP-MIB manages Spatial Reuse Protocol (SRP), also known as Dynamic Packet Transport (DPT), a Cisco ring-topology WAN technology, and belongs to Cisco's optical/ring-interface MIB family. It exposes MAC-layer identity data for SRP interfaces along with ring-level, host-level, and error counters describing traffic flow around the dual counter-rotating ring and any faults encountered. Its monitoring value is centered on interface/link performance and fault status rather than environmental hardware sensors: administrators track srpRingCounters and srpHostCounters to gauge ring traffic load and srpErrorsCounters to detect ring wraps, fiber cuts, or protocol errors, with traps under srpTrapsNotifications alerting to ring topology changes or failures. It builds on standard interface conventions (ifIndex/IF-MIB) to associate SRP counters with the underlying physical interface. It is deployed on Cisco DPT/SRP ring interface cards used in metro and long-haul optical ring networks. Engineers searching for cisco srp monitoring should note SRP here refers to Spatial Reuse Protocol/Dynamic Packet Transport, Cisco's ring-topology WAN technology, not Session Recording Protocol or other unrelated "SRP" acronyms.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SRP-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.

Supported Devices

  • Cisco DPT/SRP ring interface routers

Monitoring Examples

An operator would poll srpRingCounters and srpHostCounters on an SRP interface identified by srpMAC to baseline normal ring traffic levels, then watch srpErrorsCounters for a spike indicating ring errors such as wrap events or corrupted frames. A trap fired from srpTrapsNotifications would immediately flag a ring topology change, such as a fiber cut causing the ring to wrap and reroute traffic the long way around.

What Can Be Monitored

  • SRP interface MAC address
  • ring traffic counters
  • host traffic counters
  • ring error counters
  • ring topology change/failure notifications

How to Use in IPNetwork Monitor

Example using srpMACIpsWrapCounter OID:

Select a Cisco DPT/SRP ring interface router 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 srpMACIpsWrapCounter 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 transition from unwrap to wrap state. 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 Counter32-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.
