Description: Monitors detailed per-interface traffic statistics and error counters on Brocade network devices.

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-INTERFACE-STATS-MIB?

BROCADE-INTERFACE-STATS-MIB is a Brocade vendor MIB that supplements the standard ifTable/ifXTable with richer per-interface performance statistics, specifically utilization and watermark (peak-usage) metrics, on Brocade Ethernet switching and routing devices. It exposes performance-counter data: bits-per-second and packets-per-second rates in and out, percentage utilization in and out, jumbo frame counts, and watermark tracking over configurable time windows, plus associated notifications. This is direct performance/health monitoring of the data plane -- sustained high bcsiIfStatsInUtilization/OutUtilization or watermark threshold crossings reveal link congestion or an oversubscribed uplink before packet loss becomes visible elsewhere. It explicitly builds on and depends on the standard IETF IF-MIB (ifTable/ifXTable) for interface identity, extending rather than replacing it. It is deployed on Brocade (now Extreme Networks/Ruckus-lineage) data center and campus switches and routers. Engineers can download the BROCADE-INTERFACE-STATS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BROCADE-INTERFACE-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 Ethernet switch/router

Monitoring Examples

An operator would poll bcsiIfStatsTable/bcsiIfStatsEntry for bcsiIfStatsInUtilization and bcsiIfStatsOutUtilization per interface to spot links running near capacity, cross-referencing bcsiIfStatsInBitsPerSec/OutBitsPerSec for the actual throughput. Watching bcsiIfWatermarkTable for a bcsiIfWatermarkWindowType threshold breach, combined with a rising bcsiIfStatsInJumboFrames count, would flag an uplink that is both congested and carrying unexpectedly large frames, worth investigating for a misconfigured MTU or traffic pattern change.

What Can Be Monitored

interface utilization percentage
interface throughput (bits/packets per second)
interface watermark/peak usage
jumbo frame counts

How to Use in IPNetwork Monitor

Example using bcsiIfStatsInJumboFrames OID:

Select a Brocade Ethernet switches/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 bcsiIfStatsInJumboFrames 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 total number of jumbo packets received on the interface. 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.
