DGS-1100/ME Metro Ethernet Managed Switch CLI Reference Guide
The Switch’s default is to empty the four hardware priority queues in
order − from the highest priority hardware queue (class 3) to the
lowest priority hardware queue (class 0). Each queue will transmit all
of the packets in its buffer before allowing the next lower priority
queue to transmit its packets. A lower priority hardware queue will
be pre-empted from emptying its queue if a packet is received on a
higher priority hardware queue. The packet received on the higher
priority hardware queue transmits its packet before allowing the
lower priority hardware queue to resume clearing its queue.
Parameters
ports<portlist>
– A port or range of ports to be configured.
sp
– Specifies that the highest class of service is the first to be
processed. That is, the highest class of service should finish
emptying before the others begin.
wrr
– Specifies that the priority classes of service are to empty
packets in a weighted roundrobin (WRR) order.
Restrictions
Only administrator-level users can issue this command.
Example usage:
To configure the traffic scheduling mechanism for each COS queue:
DGS-1100-24P/ME:admin#config scheduling_mechanism sp
Command : config scheduling_mechanism sp
Success.
DGS-1100-24P/ME:admin#
show scheduling_mechanism
Purpose
To display the current traffic scheduling mechanisms in use on the
Switch.
Syntax
show scheduling_mechanism {ports<portlist>}
Description
The
show scheduling_mechanism
command displays the current
traffic scheduling mechanisms in use on the Switch.
Parameters
ports<portlist>
– A port or range of ports to be displayed.
Restrictions
None.
Example usage:
To show the scheduling mechanism on port 10:
DGS-1100-24P/ME:admin#show scheduling_mechanism
ports 10
Command : show scheduling_mechanism ports 10
