Description: Monitors network processor traffic management statistics on Brocade network forwarding hardware.

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 BROCADE-NP-TM-STATS-MIB?

BROCADE-NP-TM-STATS-MIB is a Brocade vendor MIB that reports Network Processor (NP) and Traffic Manager (TM) statistics on Brocade's NetIron XMR/MLX high-end routing platforms. It exposes per-interface packet-forwarding counters broken down by traffic category, received good/forward/discard/miscellaneous packets and unicast/broadcast/multicast breakdowns, plus packets sent to the traffic manager and bad packet counts. Its monitoring value is performance and fault visibility at the hardware forwarding-engine level: rising discard or bad-packet counts against a given interface reveal a forwarding-path problem or line-rate oversubscription on that interface's network processor, deeper diagnostic detail than standard interface counters provide. It is a standalone vendor MIB specific to Brocade's NP/TM chipset architecture, supplementing but not replacing standard IF-MIB counters. It is deployed on Brocade NetIron XMR/MLX core/edge routers where operators need chip-level forwarding diagnostics beyond basic interface statistics. Engineers can download the BROCADE-NP-TM-STATS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BROCADE-NP-TM-STATS-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

  • Brocade NetIron XMR/MLX router

Monitoring Examples

An administrator would poll brcdNPStatsTable/brcdNPStatsEntry indexed by brcdNPStatsIfIndex to compare brcdNPStatsRxForwardPkts against brcdNPStatsRxDiscardPkts and brcdNPStatsRxBadPkts, revealing whether an interface's network processor is dropping or malforming a growing share of received traffic. A sudden spike in brcdNPStatsRxMiscPkts or brcdNPStatsRxSendToTMPkts relative to brcdNPStatsRxRawGoodPkts could indicate unusual traffic being punted to the traffic manager for exception handling, a sign of a control-plane or ACL/QoS-triggered condition worth investigating.

What Can Be Monitored

  • received good/forward/discard packet counts
  • unicast/broadcast/multicast packet counts
  • packets sent to traffic manager
  • bad/miscellaneous packet counts

How to Use in IPNetwork Monitor

Example using brcdNPStatsRxRawGoodPkts OID:

Select a Brocade NetIron XMR/MLX 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 brcdNPStatsRxRawGoodPkts 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 count of good packets received from the MAC (unicast, multicast, and broadcast combined). 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 Counter64-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.
