Fortress ES-Series CLI Guide: Networking and Radio Configuration
94
NOTE: The ES2440
supports a port
speed of 1000 Mbps
when
AutoNegotia-
tion
is enabled (y), but
you cannot specify that
value for Speed.
AutoNegotiation
is enabled (
y
) by default on all ports. If you
disable
AutoNegotiation, specify the Duplex mode and
negotiation
Speed. Duplex determines whether the port will
allow only
Full
duplex communication or only
Half
duplex
communication.
Speed determines the speed at which the port
will transmit and receive data
10
Mbps or
100
Mbps.
When QoS is disabled (
EnableQoS:
n
), the port passes packets
tagged with IEEE 802.1p Quality of Service information, as
tagged, according to the Mesh Point’s four-class 802.1p QoS
implementation (Section 3.10). This is the default setting on all
ports. Enabling QoS on a given port (
EnableQoS:
y
) configures
the port to apply its assigned Quality of Service class to all
packets received on the port, overriding any IEEE 802.1p tag
already present. When you enable QoS on a port, you can then
assign the port to—and therefore apply to all traffic passed on
the port—one of the four available service classes:
TrafficClass
low
,
medium
,
high
or
critical
.
Alternatively, you can use the
set interface command with
valid switches and arguments to configure any of the above
settings on an individual Ethernet port:
# set interface -name
<InterfaceName>

3.10 Quality of Service
The Mesh Point supports Quality of Service (QoS) traffic
expediting standards, including IEEE 802.1p (Traffic Class
Expediting), the WMM® (Wi-Fi Multimedia) subset of IEEE
802.11e (QoS for Wireless LAN), and the more recent
Differentiated Services (DiffServ) model described in RFC
2474 (Definition of the Differentiated Services Field [DS Field]
in the IPv4 and IPv6 Headers) and RFC 2475 (An Architecture
for Differentiated Services).
Incoming network traffic is sorted for expediting into one of four
QoS
TrafficClass priority queues:
critical - packets in the critical queue are delivered
ahead of packets at all other QoS levels.
high - packets in the high queue are delivered after
critical packets and ahead of packets in lower-level
queues.
medium - packets in the medium queue are delivered on a
Best Effort basis: after those in higher-level queues, but
ahead of
low priority traffic.
