• wfFDDIRingOverrunRx (get wfFddiEntry.21.*)

This shows the number of LLC (logical link control) reception ring

overrun events. These errors are equivalent to “Lack of Resource” errors

on a sync or Ethernet port. Each error indicates one lost packet.

Troubleshoot a problem with reception ring overruns as follows:

– Use the following command to verify how many buffers are currently

free in the slot:

get wfKernelEntry.*.

<slot>

– Go to “Memory or Buffer Problem” in Chapter 3 if you need an

explanation of the memory issues.

– Increase the size of the reception queue by setting the wfFddiEntry.43

attribute (wfFDDICfgRxQueueLength). The maximum setting is 255.

• wfFDDITxClipFrames (

get wfFddiEntry.40.*)

This shows the number of frames clipped or dropped that the router could

not add to the driver’s transmission routine because of transmission

congestion. Determine what type of data is overrunning the transmission

port by using a network analyzer or the router's Packet Capture utility.

Use the following command to verify how many buffers are currently free

in the slot:

get wfKernelEntry.*.

<slot>

Go to “Memory or Buffer Problem” in Chapter 3 for an explanation of the

memory issues.

Increase the size of the transmission queue by setting the wfFddiEntry.42

attribute (wfFDDICfgTxQueueLength). The maximum setting is 255.

3. Enter the Technician Interface get wfFddiSmtEntry.9.* command. Or, use

this Quick Get path to access it: wfLine➔wfFddiGroup➔

wfFddiSmtGroup➔wfFddiSmtTable➔wfFddiSmtCfState.

This shows the connection of the station to the ring. The codes are a follows:

• 1 = isolated

• 2 = wrap S

• 3 = wrap A

1 2 ... 85 86 87 88 89 90 91 92 93 94 95 ... 253 254
