上下行接口进行联动（NQA+EAA+Track+BFD）（上下行联络线什么意思）
配置步骤
#
BFD echo-source-ip 1.1.1.1
#
track 1 bfd echo interface GigabitEthernet0/0 remote ip 1.1.1.1 local ip 1.1.1.2
#
rtm cli-policy test
event track 1 state negative
action 1 cli system-view
action 2 cli interface GigabitEthernet 0/1
action 3 cli shutdown
user-role network-admin
or：
#
NQA entry admin test1
type icmp-echo
destination ip 1.1.1.1
frequency 100
reaction 1 checked-element probe-fail threshold-type consecutive 4 action-type trigger-only
#
nqa schedule admin test1 start-time now lifetime forever
#
rtm cli-policy test1
event track 1 state negative
action 1 cli system-view
action 2 cli interface GigabitEthernet 0/1
action 3 cli shutdown
user-role network-admin
#
track 1 nqa entry admin test1 reaction 1
