Chapter 53 Using Automatic QoS
Using the Automatic QoS Macro on the Switch
If the above policer names are already in use, the macro attempts the following names:
• POLICE_SOFTPHONE-DSCP46-x-y-z
• POLICE_SOFTPHONE-DSCP26-x-y-z
where z = 1 to 99 starting from 1. Both names must pass with the same z value or the macro attempts the
next z value until both names are valid with the same z value. If the z = 99 attempt fails, this error
message displays and all settings remain unchanged:
Console> (enable) set port qos 4/1 autoqos voip ciscosoftphone
ERROR: QoS policer name in use, could not configure QoS policer.
Rename existing QoS policer POLICE_SOFTPHONE-DSCP46-4-1 and/or
POLICE_SOFTPHONE-DSCP26-4-1.
Autoqos did not complete. Settings remain unchanged.
Console> (enable)
QoS Disabled
When executing any port-based automatic QoS command on an interface where QoS is disabled, a
notification message appears in the CLI as follows:
Console> (enable) set port qos 4/1 autoqos voip ciscosoftphone
Port 4/1 ingress QoS configured for ciscosoftphone. Policing configured on 4/1.
QoS is disabled, changes will take effect after QoS is enabled.
It is recommended to execute the "set qos autoqos" global command if not executed
previously.
Console> (enable)
syslog Additions
Set the switch logging level to 4 or 5 for the QoS facility (set logging level qos 5) as follows:
• Log level 4 = Warnings
• Log level 5 = Notices
These sections describe the syslog additions for the automatic QoS features:
• CDP Warning —Warning Level, page 53-25
• Interface Change for All Ports Required—Warning Level, page 53-26
CDP Warning —Warning Level
When executing the port-based automatic QoS voip ciscoipphone keyword on a port where either CDP
is disabled on the port or globally, or is running in version 1 mode, a warning message displays as
follows:
Console> (enable)
2001 Jun 02 09:20:42 %QOS-4-DEVICE_CDP_DIS:Trust-Device feature enabled with CDP disabled
or running in v1 mode.
Console> (enable)
