GWCON Process

See the corresponding monitoring chapter in this manual or in the Protocol Con®guration and Monitoring Referencefor information on a speci®c protocol's console commands.

Queue

Use the queue command to display statistics about the length of input and output queues on the speci®ed interfaces. Information about input and output queues provided by the queue command includes:

vThe total number of buffers allocated

vThe low-level buffer value

vThe number of buffers currently active on the interface.

Syntax:

queue

interface#or range_of_interface#

To display information about multiple interfaces, specify the range_of_network# (or

a combination of interface# and range_of_interface#). For example, specifying queue 0 3 25-50displays the information for nets 0, 3, and 25 through 50.

To display information about one interface only, enter the interface or network number as part of the command. To obtain the interface number, use the GWCON con®guration command.

Interface

Type of interface.

Input Queue:

Alloc Number of buffers allocated to this device.

Low Low water mark for ¯ow control on this device.

Curr Current number of buffers on this device. The value will be 0 if the device is disabled.

Output Queue:

Fair Fair level for the length of the output queue on this device.

Curr Number of packets currently waiting to be transmitted on this device. For locally originated packets, the eligibility discard depends on the global low water mark described in the memory command.

The router attempts to keep at least the Low value packets available for receiving over an interface. If a packet is received and the value of Curr is less than Low, then the packet will be subject to ¯ow control. If a buffer subject to ¯ow control is to be queued on this device and the Curr level is greater than Fair, then the buffer is dropped instead of queued. The dropped buffer is displayed in the Output Discards column of the error command. It will also generate ELS event GW.036 or GW.057.
