1， 增加端口配置模板
（1）需要子接口的端口配置
set interfaces fe-2/0/1 vlan-tagging              ――――在配置接口启用封装VLAN
set interfaces fe-2/0/1 unit 424 vlan-id 424       ―――――配置子接口，VLAN 424
set interfaces fe-2/0/1 unit 424 family inet address 192.168.254.146/30  ――配置子接口地址
（2）无需子接口配置
set interfaces fe-2/0/23 unit 0 family inet address 222.60.11.154/29   ――直接配置地址
（3）E1口配置
set interfaces e1-3/0/0 encapsulation ppp 封装链路类型，包含PPP,HDLC，根据实际情况配置
set interfaces e1-3/0/0 e1-options framing unframed 封装帧格式，参数包含unframed,g704, g704-no-crc4
set interfaces e1-3/0/0 unit 0 family inet address 192.168.1.126/30 配置地址
（4）CE1配置
set interfaces ce1-4/0/0 clocking external
set interfaces ce1-4/0/0 e1-options framing g704-no-crc4
set interfaces ce1-4/0/0 partition 1 timeslots 1-31    ――――设置信道1及时隙1－31
set interfaces ce1-4/0/0 partition 1 interface-type ds  ――――子接口类型DS
set interfaces ds-4/0/0:1 encapsulation ppp         ―――――配置子接口封装ppp
set interfaces ds-4/0/0:1 unit 0 family inet filter input NYYH
set interfaces ds-4/0/0:1 unit 0 family inet address 10.238.173.197/30  ――――配置地址
（5）策略配置
set firewall filter shigonganjuMAS term 1 from source-address 10.238.173.180/30
set firewall filter shigonganjuMAS term 1 then accept
set firewall filter shigonganjuMAS term 2 from source-address 10.238.173.0/24
set firewall filter shigonganjuMAS term 2 from source-address 10.238.179.0/24
set firewall filter shigonganjuMAS term 2 then discard
set firewall filter shigonganjuMAS term 3 then accept
 
set interfaces fe-2/0/0 unit 44 family inet filter input jiaotongyinhangduanxin―――将策略应用至子接口。
