It is important to store the backup UCS archives in an environment that is as secure as where you store your private keys.. 備份的配置文件中包含哪些內容，.ucs包含以下內容： * All BIGIPspecific configuration files* BIGIP product licenses* User accounts and password information* DNS zone files* Installed SSL certificates and keys. 恢復BIGIP LTM的配置Restoring configuration dataTo restore the BIGIP system configuration, use one of the following procedures: * Restoring the configuration data for a system that is currently running system software * Installing the operating system and restoring the configuration data to a new system(1) Restoring the configuration data for a system that is currently running system software。 The PVA transforms the packet in order to redirect the packet to the appropriate pool member本命令不解析IP地址/端口號為主機名/服務名稱，同時顯示報文十二進制和文本信息，報文最大為1500字節(jié)。 X 每個報文同時以文本和十六進制顯示216。在文件中搜尋以下信息（示例）：Registration Key : J36062221005459581538313024Licensed version : Platform ID : Z100 如何使用TCPDUMP進行Troubleshooting？當業(yè)務無法正常工作時，經常需要在BIGIP上抓包進行分析定位是什么原因導致數(shù)據(jù)包沒有被常轉發(fā)。 ? 審計事件（Audit events）Audit event messages are those that the BIGIP system logs as a result of changes to the BIGIP system configuration. Logging audit events is optional. Audit logging is an optional feature that logs messages whenever a BIGIP system object, such as a virtual server or a load balancing pool, is configured。filter(notdebug)。Please refer to the following SOL for detail.. BIGIP系統(tǒng)Web管理員admin密碼忘記了，如何恢復？可以通過在命令行執(zhí)行 passwd admin重新設置admin密碼。第4章 WEB與命令行管理. 通過WEB界面修改配置時出現(xiàn)General Database Error錯誤，如何處理？如果條件允許，先將系統(tǒng)重啟后再次修改配置，看問題是否依然存在。(BIGIP管理網(wǎng)口的地址可以在BIGIP前面的液晶顯示板上看到。為了與BIGIP進行文件傳輸，可以用SSH Secure Shell Client工具帶的安全文件傳輸工具進行文件傳輸。Archives，點擊Create：配置備份好后，點擊設配置文件并下載到外部電腦上：也可以在CLI使用“b config save configfile.ucs”保存配置，使用“config install configfile.ucs”恢復配置。如果不指定路徑，默認保存在目錄“/var/local/ucs”中。Secure FileTransfer Client. 如何實時監(jiān)視BIGIP的連接狀態(tài)？請使用“b conn”命令，顯示示例如下：:46704 any:any :8 icmp:41622 any:any :8 icmp:1354 :ssh :ssh tcp:33880 :nbp any6:any udp:36599 any:any :8 icmp:35139 any:any :domain udp:35140 any:any :domain udp:35141 any:any :domain udp:35142 any:any :domain udp:35143 any:any :domain udp. 如何實時監(jiān)視BIGIP的流量情況？請使用命令“bigtop –n –delay 1”， 顯示示例如下： | bits since | bits in prior | current | Mar 2 21:17:57 | 1 seconds | timeBIGIP ACTIVE |InOutConn|InOutConn| 23:48:08 432 432 0VIRTUAL ip:port |InOutConn|InOutConn|Nodes Up:80 218984 51 0 0 0 3NODE ip:port |InOutConn|InOutConn|State:53 0 0 0 UP:80 99624 6 0 0 0 UP:80 131528 29 0 0 0 UP:80 12008 137184 1 0 0 0 UP: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上的流量情況。) 可以使用PUTTY或Secure Shell Client等SSH客戶端連接BIGIP的管理網(wǎng)口地址，進入命令行模式。如果問題依然存在，或者不允許重啟系統(tǒng)，則需要用SSH客戶端以命令行方式登陸B(tài)IGIP。方法請參考。destination(loghost)。 that is, created, modified, or deleted. There are three ways that objects can be configured:? By user action? By system action? By loading configuration dataThe BIGIP system logs the messages for these events in the file/var/log/ltm. 如何設定BIGIP　Syslog的事件級別？對于本地流量管理事件，你可以設置最小的記錄級別。BIGIP上提供了TCPDUMP抓包分析工具。 expression 匹配表達式的分組將進行解析。f51:~ tcpdump i external nn X s 1600 port 1433 and host tcpdump: listening on external 21:48: : . 302192826:302192827(1) ack 558871968 win 64360 (DF) 0x0000 012c 0800 4500 0029 38cf 4000 7f06 c3b2 .,..E..)8...... 0x0010 8bd4 6002 0a4b 092c 04b1 0599 1203 18ba ..`..K.,........ 0x0020 214f b5a0 5010 fb68 a926 0000 00 !O..P..h.amp。 The PVA sends the packet back to the switch subsystemFully accelerated traffic never reaches the internal trunk and is not processed by TMM. ） 如果采用接口編號作為i的參數(shù)，則進出該接口的數(shù)據(jù)包將先被鏡像給SCCP(SCCP是BIGIP的管理子系統(tǒng))，然后送到主機板上通過TCPDUMP抓包。在正在運行的系統(tǒng)中恢復配置文件。. 如何重置root與web admin密碼Solution ID: SOL3350 Changing account passwords for the mand line and Configuration utilityHow do I recover a lost or forgotten root password?Changing Root and Support PasswordsTo reset a lost or forgotten root or support password, perform the following steps:1. Boot the system into singleuser mode. Note: For specific instructions, refer to SOL4178: How do I boot BIGIP into singleuser mode?2. Type the following mands: mount apasswd accountFor example:passwd root3. When prompted, enter a new password.4. Type exit or reboot to return to the normal operating mode. After the system reboots, you should be able to log in using the new password.Changing an Administrative Account PasswordNote: If you have not lost the password, but want to change it, F5 Networks remends that you do so using the Configuration utility. Changing the admin password from the mand line will result in passwords that are different on each BIGIP in a redundant pair, which will prevent configuration synchronization from working correctly. For specific instructions about how to change a Configuration utility admin password, refer to the Managing User Accounts chapter of the BIGIP Systems Management Guide.To reset a lost Configuration utility admin account password fr。 however, if you restored the backup on a different device, and received the errors noted in step 3 you will need to perform steps 6 and 7. 6.
