Environment

NetIQ AppManager 6.x
NetIQ AppManager 7.0.x

Situation

NetworkDevice_FrameRelayLink_Util Knolwedge Script is incorrectly reporting the bandwidth capacity.

The bandwidth capacity for the frame relay link is defined to be a specific value, but the knowledge script returns a different value.
Error (example):

Bandwidth utilization exceeded threshold.
Bandwidth utilization of 103.45% exceeded threshold of 90%.

Device name: rtr1.hou.netiq.com
Link: Serial0/0:1.500
DLCI/Interface Index: 500/58
Bandwidth capacity: 193,000 bytes/sec
Bandwidth utilization: 103.45%
Inbound: 103.45%
Outbound: 22.76%
Bandwidth utilization threshold: 90%
Bytes received: 59,899,924 (199,666.41 bytes/sec) Bytes sent: 13,178,557 (43,928.52 bytes/sec)

Resolution

The bandwidth capacity is being calucated correctly.

Cause

The mib values for interface speed or CIR are measured in bits per second (bps). AppManager gets this value converting ifspeed (or frCircuitThroughput) from bps to Bps.

Additional Information

Formerly known as NETIQKB52614

The interface speed for Serial0/0:1.500 interface in the example above is configured as: interfaces.ifTable.ifEntry.ifSpeed.58 = Gauge32: 1544000 1544000 / 8 = 193,000 Bps
