4 Apply the map on a specic interface or on system-qos global level.
• Interface level
OS10(conf-if-eth1/1/1)# trust-map dscp example-dscp-trustmap-name
• System-qos level
OS10(config-sys-qos)# trust-map dscp example-dscp-trustmap-name
Apply DSCP trust map
You must apply the trust map at the interface or system-qos level. To apply the trust map on a specic interface or on system-qos (global)
level:
• Interface level
OS10(conf-if-eth1/1/1)# trust-map dscp example-dscp-trustmap-name
• System-qos level
OS10(config-sys-qos)# trust-map dscp example-dscp-trustmap-name
ACL-based classication
Classify the ingress trac by matching the packet elds using ACL entries.
Classify the trac ows based on QoS-specic elds or generic elds, using IP or MAC ACLs. Create a class-map template to match the
elds.
OS10 allows matching any of the elds or all the elds based on the match type you congure in the class-map.
Use the access-group match lter to match MAC or IP ACLs. You can congure a maximum of four access-group lters in a class-map:
• 802.1p CoS
• VLAN ID (802.1.Q)
• DSCP + ECN
• IP precedence
OS10 supports conguring a range of or comma-separated values of match lters. When you apply the same match lter with new values,
the system overwrites the previous values with the new values.
Congure ACL based classication
1 Create a class-map of type qos.
OS10(config)# class-map type qos example-cmap-cos
2 Dene the eld to match:
OS10(config-cmap-qos)# match cos 3
3 Create a qos-type policy-map to refer the classes to.
OS10(config)# policy-map type qos example-pmap-cos
4 Refer the class-maps in the policy-map and dene the required action for the ows.
OS10# configure terminal
OS10(config)# class-map type qos example-cmap-cos
OS10(config-cmap-qos)# match cos 3
OS10(config-cmap-qos)# exit
OS10(config)# policy-map type qos example-pmap-cos
OS10(config-pmap-qos)# class example-cmap-cos
OS10(config-pmap-c-qos)# set qos-group 3
