Strictly ordered
Packets are sent in the order that they are received. This may be a good choice for signaling traffic
where there can be absolutely no disruption in packet transmission.
DROP
Packets directed to this queue are discarded.
CIR (kbps):
This specifies the “Committed Information Rate” in kbps (1000 bits per second). The range is 0 up to the
licensed rate. If the FX WAN optimization feature is not licensed, then up to 700000 kbps can be specified.
The default is 0. This field is disabled if “Strict Priority” was configured as the drain algorithm.
Note:
To minimize jitter, set the CIR for high priority traffic high enough to accommodate peak
usage requirements.
MIR (kbps):
This specifies the “Maximum Information Rate” in kbps (1000 bits per second). The range is 0 up to the
licensed rate. If the FX WAN optimization feature is not licensed then up to 500000 can be specified. If 0
is specified, some packets may still be sent at a very low rate, to inhibit all traffic then a “DROP” filter
should be defined. The default is the max licensed rate. This field is disabled if “Strict Priority” was
configured as the drain algorithm.
Priority:
This is the drain priority for the queues. Classes of equal priorities will be treated the same, with rates
split proportionally between them. The minimum value (highest priority) is 1; the maximum value (lowest
priority) is 8.
Default for unmatched packets:
If set, then this is the queue that packets which have not matched any of the queue filters in a group will
be directed to. If no queue is designated as 'Default' for a group, then unmatched packets will be directed
to the lowest priority queue in the group.
Header compression:
This enables/disables header compression and packet aggregation for this queue. For header
compression to occur, you must also configure header compression in the group this queue is a member
of. If header compression is enabled then WAN optimization features such as caching can’t be performed
on traffic associated with this queue. When configuring header compression, you can choose to perform
header compression, or both header and payload compression.
Aggregation interval (msecs):
This specifies the packet aggregation flush interval in milliseconds if packet compression is enabled.
The minimum and default value is 10 msec. The maximum is 1000 msec.
Threshold to trigger payload compression:
If ‘header and payload’ compression is selected, this value specifies the minimum payload size to
trigger payload compression. The default is 300 bytes.
Filters:
This is a read-only list of filters that are currently assigned to this queue.
