Auto-QoS-MED
Macro Examples
Note
LLDP must be enabled globally before Auto-QoS-MED
configuration.
Link Layer Discovery Protocol (LLDP) and Link Layer Discovery Protocol
for Media Endpoint Devices (LLDP-MED) allow Ethernet network devices,
such as switches and routers, to receive and transmit device-related
information to directly-connected devices. LLDP-MED is used between a
LAN network connectivity device, such the AT-8100 switch, and media
endpoint device, such as an IP phone. For more information about LLDP-
MED, see Chapter 78, “LLDP and LLDP-MED” on page 1229.
You can use the AUTO-QOS-MED command to support a voice VLAN and
optionally specify to trust DSCP (instead of CoS) ingress traffic on a port.
This command also enables LLDP-MED support. In addition, you can set
the AUTO-QOS-MED command to specify the type of trusted traffic
without assigning a voice VLAN to the switch.
With the AUTO-QOS-MED command, you can create the following
scenarios:

 “Auto-QoS-MED with Trust DSCP Functionality and Voice VLAN
Support” on page 1685
 “Auto-QoS Functionality” on page 1681
 “Auto-QoS with Trust DSCP Functionality” on page 1682
For more information about this command, see “AUTO-QOS-MED” on
page 1597.

weight 3,3,1,1,2,0,0,0 Assigns a weight to the eight default DSCP queues

0. DSCP queues 0 and 1 are assigned a weight of 3.
DSCP queues 2 and 3 are assigned a weight of 1.
DSCP queue 4 is assigned a weight of 2. DSCP
