Enabling Auto-QoS Support on the Switch
Note
QoS and LLDP must be manually enabled globally before the Auto-
QoS macro can be run. Once QoS is enabled globally, the switch will
automatically trust CoS, unless you specify trust DSCP.
Auto-QoS is an intelligent macro that permits you to enter one command
that enables all the appropriate features for the recommended QoS
settings on edge and uplink ports. There are two types of Auto-QoS
scenarios: without LLDP-MED phone-port support and with LLDP-MED
phone-port support. You configure the Auto-QoS scenarios on a port.
Before configuring Auto QoS, Allied Telesis recommends that there are no
voice VLAN or QoS settings on the switch. These settings may interfere
with the commands automatically generated when enabling the Auto-QoS
macros. For information about the voice VLAN commands, see Chapter
68, “Voice VLAN Commands” on page 1029. However, both Auto-QoS
configuration and manual QoS configuration can coexist on the switch, as
long as their settings do not conflict.
Note
The term manual QoS configuration refers to entering the QoS
commands individually at the command line.
See Table 223 for the list of the two commands that allow you to configure
the Auto-QoS macros.
For examples of these commands, see the following sections:

Table 223. Auto QoS Commands
To Do this Task Use this Command
Enable Auto-QoS support for a voice VLAN
for a non-LLDP-MED phone port and
optionally specify to trust DSCP, instead of
CoS, ingress traffic on the switch. auto-qos [ voice | trust
dscp ]
Enable Auto-QoS-MED support for a voice
VLAN for a LLDP-MED phone port and
optionally specify to trust DSCP, instead of
CoS, ingress traffic on the switch. auto-qos-med [ voice | trust
dscp ]
