中兴c300配置cfm抓不到包

double05101

如下配置后，不能抓到cfm的报文，求助各位大神帮忙解答。
1 配置vlan，上联盘的两个端口在vlan中

vlan 4000
exit
vlan 1000
exit
interface gei_1/20/3
switchport vlan 4000,1000 tag
exit
interface gei_1/20/4
switchport vlan 4000,1000 tag
exit

此时3口4口打业务是通的（不带tag，带1000和带100的均能通）
2 配置cfm
cfm enable
cfm create md session 1 name mdtest level 7
ma create session 1 name matest
ccm timer-interval 1
protect vlan
primary vlan 1000
primary vlan 4000
create rmep session 2 2 remote-mac 0000.0001.0001
create mep session 1 1 direction down
ccm-send enable
state enable
relate-to rmep 2
exit
assign mep 1 to interface gei_1/20/3
3 查看cfm配置
