Catalyst 2970/3560/3750—Trusted Endpoint Model
Configuration
Version 3.3
This section includes the following topics:
Configuration
Catalyst MLS QoS Verification Commands
Catalyst 2970/3560/3750—QoS Considerations and Design
The Trusted Endpoint model configuration for the Catalyst 2970/3550 is identical to the switches
previously discussed (namely, the Catalyst 2950 and 3550) and is shown below.
Example 2-27 Catalyst 2970/3560/3750—Trusted Endpoint Model Configuration
CAT2970(config)#interface GigabitEthernet0/1
CAT2970(config-if)#mls qos trust dscp
Catalyst MLS QoS Verification Commands
Catalyst MLS QoS verification commands for the Trusted Endpoint model include the following:
show mls qos
show mls qos interface
Catalyst 2970/3560/3750—Auto QoS VoIP Model
The Catalyst 2970/3560/3750 supports AutoQoS VoIP with the following keyword options:
auto qos voip cisco-phone
auto qos voip cisco-softphone
auto qos voip trust
When you enable AutoQoS VoIP on the Catalyst 2970/3560/3750 by using the auto qos voip
cisco-phone, the auto qos voip cisco-softphone, or the auto qos voip trust interface configuration
command, the switch automatically generates a QoS configuration based on the traffic type and ingress
packet label and applies the commands listed in Table 2-3 to the interface.
Table 2-3 Catalyst 2970/3560/3750 Auto-QoS Generated Configuration
Description Automatically Generated Command
The switch automatically enables standard
QoS and configures the CoS-to-DSCP
map (maps CoS values in incoming
packets to a DSCP value).
C2970(config)# mls qos
C2970(config)# mls qos map cos-dscp 0 8 16 26 32
