3.10.0.0.2 DiffServ QoS and DSCP Mapping
DiffServ increases the number of definable priority levels over
the earlier IP precedence tagging standards, permitting greater
granularity in traffic QoS sorting.
DiffServ QoS information is conveyed in the six most significant
bits—the Differentiated Services Codepoint, or DSCP—in the
packet header’s DS field.
You can reconfigure the
DSCP-to-TrafficClass map with
set qos:
# set qos -dscp 0,1,2...63 -priority low|medium|high|critical
3.11 VLANs Implementation
VLANs (virtual local area networks) are
Disabled
on the Mesh
Point by default: VLAN traffic is not passed. Packets received
with VLAN tags are discarded, and per-port VLAN settings are
disregarded.
When FastPath Mesh (
mesh) is used for bridging, the Mesh
Point can support up to eight VLANs in
enabled VLAN Mode.
When bridging is
off, the Mesh Point can support up to 48
VLANs in
enabled or in translate VLAN Mode.
3.11.0.0.1 Enabled VLAN Mode
You can set vlan -mode to enabled on the Mesh Point only
when the global bridging mode is set to
mesh or off. The
enabled VLAN Mode is incompatible with the default global
bridging setting, STP.
NOTE: Bridging
configuration is
described in Section 3.2.
When VLANs are
Enabled
, the Mesh Point implements port-
based VLANs, in which the VLAN identity of an untagged frame
is derived from the access port on which it is transmitted or
received.
Each of the Mesh Point’s network interfaces can be associated
with a particular VLAN and configured as a VLAN
trunk
port or
access
port.
VLAN traffic is handled as shown in Table 3.10.
