Chapter 39 Configuring QoS
Table 39-5 Generated Auto-QoS Configuration (continued)
Description
The switch automatically configures the egress queue buffer
sizes. It configures the bandwidth and the SRR mode (shaped
or shared) on the egress queues mapped to the port.
If you entered the auto qos voip trust command, the switch
automatically sets the ingress classification to trust the CoS
value received in the packet on a nonrouted port by using the
mls qos trust cos command or to trust the DSCP value
received in the packet on a routed port by using the mls qos
trust dscp command.
If you entered the auto qos voip cisco-phone command, the
switch automatically enables the trusted boundary feature,
which uses the CDP to detect the presence or absence of a
Cisco IP Phone.
If you entered the auto qos voip cisco-softphone command,
the switch automatically creates class maps and policy maps.
After creating the class maps and policy maps, the switch
automatically applies the policy map called
AutoQoS-Police-SoftPhone to an ingress interface on which
auto-QoS with the Cisco SoftPhone feature is enabled.
