ACL based classification
Classify the ingress traffic by matching the packet fields using ACL entries.
Classify the traffic flows based on QoS-specific fields or generic fields, using IP or MAC ACLs. Create a class-map template to
match the fields.
OS10 allows matching any of the fields or all the fields based on the match type you configure in the class-map.
Use the access-group match filter to match MAC or IP ACLs. You can configure a maximum of four access-group filters in a
class-map:
● 802.1p CoS
● VLAN ID (802.1.Q)
● DSCP + ECN
● IP precedence
OS10 supports configuring a range of or comma-separated values of match filters. When you apply the same match filter with
new values, the system overwrites the previous values with the new values.
Configure ACL based classification
1. Create a class-map of type qos.
OS10(config)# class-map cmap
2. Define the fields to match, based on:
● 802.1p CoS
OS10(config-cmap-qos)# match cos 0,4-7
● all the 802.1p CoS values excluding a few
OS10(config-cmap-qos)# match not cos 3,4
● VLAN ID (range of or comma separated VLAN match is not supported)
OS10(config-cmap-qos)# match vlan 100
● IP DSCP
OS10(config-cmap-qos)# match ip dscp 3,5,20-30
● IP DSCP + ECN
OS10(config-cmap-qos)# match ip dscp 3,5,20-30 ecn 2
● IP precedence
OS10(config-cmap-qos)# match ip precedence 2
● IPv6 DSCP
OS10(config-cmap-qos)# match ipv6 dscp 3,5,20-30
● IPv6 DSCP + ECN
OS10(config-cmap-qos)# match ipv6 dscp 3,5,20-30 ecn 2
● IPv6 precedence
OS10(config-cmap-qos)# match ipv6 precedence 2
