Juniper SRX防火墙接口包括两种：

1、管理接口，默认为fxp0

2、业务接口，这里通常是指配置用来跑业务的板卡接口，如：SRX3k SFB 12GE（8x 1GE-TX 4x 1GE-SFP）

 

对于管理接口，配置IP后即可ping通：

netscreen@SRX3600# set interfaces fxp0 unit 0 family inet address 10.200.27.156/16

C:\>ping 10.200.27.156

Pinging 10.200.27.156 with 32 bytes of data:

Ping statistics for 10.200.27.156:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

如果需要telnet/ssh管理接口IP地址，则还需要放开系统层面级的telnet/ssh服务：

netscreen@SRX3600# set system services ssh
netscreen@SRX3600# set system services telnet

 

对于业务接口，仅仅配置IP地址无法ping：

netscreen@SRX3600# set interfaces ge-0/0/0 unit 0 family inet address 10.200.51.203/16

C:\>ping 10.200.51.203

Pinging 10.200.51.203 with 32 bytes of data:

Ping statistics for 10.200.51.203:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

还需要该接口分配到相应的Zones，同时开放相应的服务（ping/telnet/ssh）：

netscreen@SRX3600# set security zones security-zone untrust interfaces ge-0/0/0.0
netscreen@SRX3600# set security zones security-zone untrust interfaces ge-0/0/0.0 host-inbound-traffic system-services ping
netscreen@SRX3600# set security zones security-zone untrust interfaces ge-0/0/0.0 host-inbound-traffic system-services telnet
netscreen@SRX3600# set security zones security-zone untrust interfaces ge-0/0/0.0 host-inbound-traffic system-services ssh
