Reference Guide
1 Create a default DSCP trust map.
OS10(config)# trust dscp-map default
OS10(config-tmap-dscp-map)#
2 Apply the map on a specic interface or on system-qos (global) level.
• Interface level
OS10(conf-if-eth1/1/1)# trust-map dscp default
• System-qos level
OS10(config-sys-qos)# trust-map dscp default
ACL based classication
Classify the ingress trac by matching the packet elds using ACL entries.
You can classify the trac ows based on QoS specic elds or generic elds, using IP or MAC ACLs. Create class-map template to match
the elds.
OS10 allows matching any of the elds or all the elds based on the match type congured in the class-map.
Use access-group match lter to match MAC or IP ACLs. You can congure a maximum of 4 access-group lters in a class-map:
• 802.1p CoS
• VLAN ID (802.1.Q)
• DSCP + ECN
• IP precedence
OS10 supports conguring 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.
Congure ACL based classication
1 Create a class-map of type qos.
OS10(config)# class-map cmap
2 Dene the elds to be matched, 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
• any IP (IPv4 or IPv6) precedence
OS10(config-cmap-qos)# match ip-any precedence 2
