在一台华为ATN950B上配置如下(默认配置未列出）：
#
undo lldp enable
#
bfd
#
mpls lsr-id 1.1.1.1
mpls
#
mpls l2vpn
#
interface GigabitEthernet0/1/0
undo shutdown
#
interface GigabitEthernet0/1/0.31
vlan-type dot1q 31
ip address 3.100.85.214 255.255.255.252
mpls
#
ip route-static 1.1.1.2 255.255.255.255 3.100.85.213
#
static-lsp ingress ingress-1 destination 1.1.1.2 32 nexthop 3.100.85.213 out-label 101

#
interface GigabitEthernet0/1/5
undo shutdown
mpls static-l2vc destination 1.1.1.2 10001 transmit-vpn-label 111 receive-vpn-label 102 control-word

1槽位为D1EME8T盘，在输入如下命令行时总是提示不对：
[HUAWEI]interface GigabitEthernet 0/1/5
[HUAWEI-GigabitEthernet0/1/5]mpls l2vpn pw bfd
Error: The current interface does not be configured with VC.
手册上说动态BFD支持静态PW，为什么配置不起呢？一直搞不懂，翻了1天资料了，仍然无解，请教下各位大大，不胜感激！
