The example output above shows the Mesh Point’s default
QoS configuration.
You can restore the default QoS
Tags and DSCP mappings with
the
set qos command:
# set qos -resetdefaults
The -resetdefaults switch takes no arguments and should
only be used by itself, without any other
set qos switches.
3.10.0.0.1 IP Precedence QoS Tags and Mapping
When the Mesh Point is configured to use VLANs (vlan -mode
enabled or translate (refer to Section 3.11), 802.1p priority
tags are conveyed, over interfaces with a VLAN
-switchingmode of trunk (refer to Section 3.9), as part of the
VLAN tags included in packet headers.
NOTE: Per-port
QoS settings (refer
to Section 3.9) override
any priority information
in the packet headers of
traffic on that port.
When VLANs are disabled, the Mesh Point drops regular VLAN
traffic but accepts specialized priority-tagged packets in order
to support Ethernet QoS exclusive of a VLAN implementation.
(Priority-tagged packets use a VLAN tag with a VLAN ID of
zero, a null-value VLAN ID.)
When no VLAN tags are present in wireless packets, QoS
priority tags can be conveyed in their 802.11 headers.
When enabled on the BSS (see Section 3.4.9.6), WMM Quality
of Service is in effect for wireless bridge links, the connections
formed between bridging BSSs on Mesh Point radios (refer to
Section 3.4.9.2).
NOTE: To deter-
mine/configure
WMM QoS capability
for a given device, con-
sult its documentation.
QoS is negotiated individually for devices connecting to a
WMM-enabled BSS configured to provide wireless access
points (APs). If the connecting device supports and is enabled
for WMM QoS, the Mesh Point prioritizes traffic for the device
according to its priority tags. Traffic from devices that do not
send priority tags is marked for Medium (or Best Effort) QoS
handling.
WMM is enabled by default on new BSSs (refer to Section
3.4.9.6).
NOTE: You can
disable 802.1p QoS
on the Mesh Point by
assigning all eight
802.1p tags to the same
priority level.
The Mesh Point sorts 802.1p-tagged packets into QoS
TrafficClass priority queues according to the configurable
QoS
Tags map. The default mapping conforms to IEEE
standard 802.1D, MAC Bridges, Annex G.
You can reconfigure the
Tags-to-TrafficClass map with
set qos:
# set qos -tag 0,1,2...7 -priority low|medium|high|critical
