example, DiffServ replacement is configured such that QP8 is mapped to code point 56. Matching
packets are sent to QP8, and the DSCP value in the packet is set to 56:
entry voice_entry {
if {
source-address 2.2.2.2/32;
} then {
qosprofile qp8;
replace-dscp;
}
}
See Chapter 15, "Quality of
replacement.

Table 34 lists the match conditions that can be used with ACLs, and whether the condition can be used
for ingress ACLs only, or with both ingress and egress. The conditions are case-insensitive; for example,
