REASON SWITCHES-TM-EN-3
store excess data in an internal buffer to be sent later, thus this function would
require memory available to store frames. Possible configurations are as follows.
o Port: indicate the ports to be configured at this row. Port field is a
hyperlink that allows accessing QoS Egress Port Scheduler and
Shapers settings. Port scheduler menu allows configuring port to
operate in Strict Priority scheduler mode or 6 Queues Weighted
mode. Possible configuration after clicking Port number hyperlink
are as follows:
 Scheduler Mode: indicates which mode port scheduler is
operating. Each port can be freely configured to operate
as strict or weighted mode. Allowed values are Strict
Priority and 6 Queues Weighted. Strict priority means that
lower priority queue will only start forwarding frames
after higher priority queue is empty. 6 queues weighted
means that queues CoS 0 to 5 will be weighted and
frames will be randomly discarded based on the weight
configuration;
 Queue Shaper: indicates queue rate to be used by
shaping function. Each queue has its own shaper
configuration. If congestion happens at a given queue at
the port, queue shapers will perform switching functions
to guarantee that average traffic at that queue does not
excess Queue Shaper Rate configured. Possible
configuration are as follows:
 Enable: enable Queue Shaper function at the Cos
queue. Checkbox selected means function
enabled to that queue, and checkbox empty
means disabled;
 Rate: indicates maximum average traffic allowed
in the queue. Sporadic peak traffic will be stored
at internal buffer to be forwarded when peak
traffic is lower than Queue Shaper Rate value.
Allowed values are integer values and limits
depend on the Unit used. Range of 100 to
1,000,000 is allowed when kbps or fps units are
used. Range of 1 to 32,000 is allowed when Mbps
or kfps units are used;
 Unit: indicates which unit should be used with
Rate value to limit traffic. Allowed values are
kbps, Mbps, fps and kfps;
 Excess: enable this queue to use (if necessary)
excess of bandwidth when compared to the
Queue Shaper Rate value. Checkbox selected
means function enabled to that queue, and
checkbox empty means disabled.
