The NE40E version is V600R001C00SPC800
According to the Topo.vsd,there is a VRRP between the two NE40Es,and the VRRP virtual IP works as the gateway of RNC,we do QOS deployment in the Topology:RNC make different serivce with different DSCP value,The NE40E configures the "turst upstream default" command to trust the DSCP value. Because RNC has divided the serives into EF,AF and BE ,so the NE40E outbound interfaces should see the EF queue has some traffic ,but in fact there is no traffic in the interface to NodeB of "backup NE40E"

Use "trust upstream default vlan XX" instead of "trust upstream default"
Please See the different of attachments "Wrong Command of NE40E.txt"
and "Right Command of NE40E.txt"
The command "trust upstream default " only take effect at L3 interface,If you want do trust operation at L2 interfaces ,you need to use the specific command "trust upstream default vlan XX"(XX stand for the VLAN you want trust)
To study the different of the similar commands will make you to have less mistake.
