See the corresponding monitoring chapter in this manual or in the
Protocol
Configuration and Monitoring Reference
for information on a specific protocol’s
console commands.
Queue
Use the queue command to display statistics about the length of input and output
queues on the specified interfaces. Information about input and output queues
provided by the queue command includes:
v The total number of buffers allocated
v The low-level buffer value
v The 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 25-50 displays 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
configuration command.
Example:

1 PPP/0 24 4 24 4 0
2 FR/0 24 4 24 5 0
Nt Network interface number associated with the software.
Interface
Type of interface.
Input Queue:
Alloc Number of buffers allocated to this device.
Low Low water mark for flow 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 flow control. If a buffer subject to flow 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.
