defaults for mapping CoS values to a forwarding queue.
CoS Default
Interface
Interface to which the CoS configuration
applies.
Default CoS
Determines the default CoS value for
incoming packets for which a VLAN tag is not defined. The
possible field values are

% of WRR Bandwidth
Displays the amount of bandwidth
assigned to the queue. These values are fixed and are not

Modifying queue scheduling affects the queue settings
globally. The
Bandwidth
screen is not used with the Service
mode, as bandwidth settings are based on services. This
feature has been added to version 1.2 of the SRW2024/
SRW2016 and version 1.1 of the SRW224G4/SRW248G4.
