Mapping between the DSCP value and forwarding queue cannot be changed. However, mapping between DSCP values and other
properties can be changed as follows:
•
DSCP to internal forwarding priority mapping—You can change the mapping between the DSCP value and the internal forwarding
priority value from the default values shown in the above tables. This mapping is used for CoS marking and determining the
internal priority when the trust level is DSCP. Refer to
Changing the DSCP to internal forwarding priority mappings
on page 34.
•
VLAN priority (802.1p) to hardware forwarding queue—You can change the mapping between the 802.1p value and hardware
forwarding queue from the default value. Refer to
Changing the VLAN priority 802.1p to hardware forwarding queue mappings
on
page 35.
QoS for Ruckus ICX stackable devices
Ruckus FastIron units in a traditional stack support QoS.
Units in a stack communicate the stack topology information and other proprietary control information through the stacking links. For more
information about stacking links and traditional stack technology, refer to the
Ruckus FastIron Stacking Configuration Guide
.
In addition to control information, the stacking links also carry user network data packets. In a traditional stack topology, the priority of
stacking-specific control packets is elevated above that of data path packets, preventing loss of control packets, and timed retries that
affect performance. This prioritization also prevents stack topology changes that may occur if enough stack topology information packets
are lost.
Traditional stack technology reserves one QoS profile to provide a higher priority for stack topology and control traffic.
