SC LPUs include LSQ1GP24SC LPUs and so on, SA LPUs include LSQ1FP48SA LPUs and so on, EA

LPU to implement one-to-one VLAN mapping. In this policy, only one matching rule,
if-match
service-vlan-id
, can be defined, and the action can only be
remark customer-vlan-id
or
remark
customer-vlan-id
together with
remark dot1p
.
