2.3. 如何与BIG-IP进行文件传输？
出于安全考虑，BIG-IP不允许用ftp登陆到BIG-IP上进行文件的上传与下载。
为了与BIG-IP进行文件传输，可以用SSH Secure Shell Client工具带的安全文件传输工具进行文件传输。
2.4. 如何实时监视BIG-IP的连接状态？
请使用“b conn”命令，显示示例如下：
192.168.1.254:46704 <-> any:any <-> 192.168.1.1:8 icmp
192.168.4.33:41622 <-> any:any <-> 192.168.20.1:8 icmp
127.1.1.1:33880 <-> 127.1.1.2:nbp <-> any6:any udp
192.168.4.33:36599 <-> any:any <-> 192.168.20.3:8 icmp
192.168.1.254:35139 <-> any:any <-> 192.168.1.1:domain udp
192.168.1.254:35140 <-> any:any <-> 192.168.1.1:domain udp
192.168.1.254:35141 <-> any:any <-> 192.168.1.1:domain udp
192.168.1.254:35142 <-> any:any <-> 192.168.1.1:domain udp
192.168.1.254:35143 <-> any:any <-> 192.168.1.1:domain udp
2.5. 如何实时监视BIG-IP的流量情况？
请使用命令“bigtop –n –delay
| bits since | bits in prior | current
| Mar 2 21:17:57 | 1 seconds | time
BIG-IP ACTIVE |---In----Out---
bigip4.f5training.cn
VIRTUAL ip:port |---In----Out---
NODE ip:port |---In----Out---
192.168.1.1:53
192.168.20.2:80 99624
192.168.20.1:80 131528
192.168.20.3:80 12008 137184 1 0 0 0 UP
192.168.1.2:53 0 0 0 0 0 0 NODE DOWN
其中bits in prior 1 second列出的In Out是各Virtual Server及Node上的流量情况。
