QoS
- Changing ToS-based QoS mappings
To reapply an ACL following an ACL configuration change, enter the ip access-group command
at the interface configuration level of the CLI as shown in the following example.
Console(config)# interface ethernet 1/2
Console(config-if)# ip access-group david in
QoS
Quality of Service (QoS) features prioritize the use of bandwidth in a switch. When QoS features are
enabled, traffic is classified as it arrives at the switch, and processed on the basis of configured
priorities. Traffic can be dropped, prioritized for delivery, or subjected to limited delivery options,
depending on how you configure QoS features.
QoS show commands
show qos map trust-mode
Syntax: show qos map trust-mode interface interface
• interface
• ethernet unit/port
• unit - Unit identifier. (Range: 1)
• port - Port number. (Range: 1-12)
• port-channel channel-id (Range: 1-12)
This command displays the QoS mapping mode.
Console# show qos map trust-mode interface ethernet 1/5
Information of Eth 1/5
COS Map mode: CoS mode
show qos map cos-dscp
Syntax: show qos map cos-dscp interface interface
• interface
• ethernet unit/port
• unit - Unit identifier. (Range: 1)
• port - Port number. (Range: 1-12)
• port-channel channel-id (Range: 1-12)
If a packet arrives with a 802.1Q header but it is not an IP packet, then this table is used to map
the Class of Service/Canonical Format Indicator (CoS/CFI) values in the ingress packet to priority
and drop precedence values for internal processing
This command shows the ingress CoS/CFI to internal Differentiated Services Code Point Service
(DSCP) map.
Console# show qos map cos-dscp interface ethernet 1/5
CoS Information of Eth 1/5
