Allocating Memory for the Packet Capture File

You must allocate memory to store the Packet Capture file in order to capture

packets. By default, the Packet Capture file uses 0 bytes of memory.

Allocate memory to the Packet Capture file as follows:

Enter the following command to display the maximum number of

contiguous bytes available:

get wfKernelEntry.6.

represents the wfKernelMemoryMaxSegFree attribute.

Enter the following command to specify the size of the Packet Capture

file stored in memory:

set wfPktCaptureEntry.8.

<line_no.> <value>

;commit

•

represents the wfPktCaptureBufSize attribute.

•

<line_no.>

is the number displayed after you issued the

get

command in

“Creating an Instance of Packet Capture

” on page B-7.

To list the current line numbers associated with Packet Capture, enter the

command

list instances wfPktCaptureEntry

•

<value>

is the number of KB of available contiguous memory, minus

200 KB. The value 1 represents 1024 bytes (1 KB) of memory allocated

for the Packet Capture file; the value 2 represents 2 KB.

To calculate the value, subtract 200 KB from the lowest number displayed

in response to the

get

command that you entered in step 1; then, divide

this number by 1024. The result is the maximum value that Nortel

Networks recommends that you enter.

The less memory you allocate to Packet Capture, the lower the chance that the

processor will reset because of a memory problem. However, you do need to

allocate enough memory to store the packets you want to capture.

Note:

The allocation of memory varies. If the processors have memory

restrictions, enter this command every 15 seconds for 2 to 3 minutes and

record each response.
