6.2 Legacy CLI Command Comparison

For those familiar with QoS configuration using the legacy CLI commands, it may be a useful exercise to
compare configuration command sequences using legacy commands and the new traffic-profile filter set
support. Revisiting an earlier example, suppose an administrator wishes to remark traffic that is
inappropriately prioritized (i.e., remark traffic with the highest priority DSCP values CS7 and CS6 to AF41)
on a specific VLAN. Using the traffic-profile filter set support, the following commands are required:
qos traffic classifier name dscpChk ds-field 56 vlan-min 5 vlan-max 5 update-dscp
34 block dsRem eval-order 1
qos traffic classifier name dscpChk ds-field 48 vlan-min 5 vlan-max 5 update-dscp
34 block dsRem eval-order 2
qos traffic set port 8 name dscpChk committed-rate 64 committed-burst 16384 drop
enable track-statistics individual
Using the legacy QoS CLI commands, a more expansive list of commands must be executed to initiate
the same traffic treatment:
qos ip-element 1 ds-field 56
qos ip-element 2 ds-field 48
qos l2-element 1 vlan-min 5 vlan-max 5 ethertype 0x0800
qos classifier 1 set-id 1 element-type ip element-id 1
qos classifier 2 set-id 1 element-type l2 element-id 1
qos classifier 3 set-id 2 element-type ip element-id 2
qos classifier 4 set-id 2 element-type l2 element-id 1
