华为9312交换机log信息下载操作指引通过display logbuffer命令可以查询到华为9312交换机上的log信息，但是由于logbuffer 的大小有限，往往只能看到很短时间内的日志信息，历史的log信息就无法通过该命令进行查看；需要查询历史log信息，需要通过FTP方式登陆9312交换机，下载历史log信息，具体操作步骤如下1、开启9312交换机的FTP访问权限，在全局模式下输入命令：[GDGZ-MA-IPMAN-FC-SW01-S9312]ftp server enable2、登陆账号FTP访问权限放通。

在service-type中增加ftp，另外需要配置ftp-directory，没有配置ftp-directory，则无法成功FTP登陆[GDGZ-MA-IPMAN-FC-SW01-S9312-aaa] local-user hjy139******** service-type ftp telnet [GDGZ-MA-IPMAN-FC-SW01-S9312-aaa]local-user hjy139******** ftp-directory cfcard:/3、在全局模式下查看9312交换机的历史log文件，历史log文件存放位置在cfcard:/ logfile<GDGZ-MA-IPMAN-FC-SW01-S9312>dirDirectory of cfcard:/Idx Attr Size(Byte) Date Time FileName0 drw- - Jan 28 2011 08:00:56 logfile1 -rw- 198 Jan 05 2011 17:14:40 $_patchstate_a2 -rw- 4 Jan 28 2011 13:40:20 snmpnotilog.txt3 -rw- 8,882 Jan 15 2011 10:04:30 private-data.txt4 -rw- 6,693 Jan 28 2011 14:25:16 vrpcfg.zip5 -rw- 1,730,668 Jan 05 2011 16:20:56 s9300v100r001sph017.pat6 -rw- 22,313,196 Dec 05 2009 13:44:16 7 -rw- 140,708 Jan 05 2011 17:14:40 patchhistory8 -rw- 0 Dec 17 2009 08:36:46 stickymac.txt9 -rw- 1,217,429 Mar 09 2010 15:36:22 s9300v100r001sph012.pat500,192 KB total (415,904 KB free)<GDGZ-MA-IPMAN-FC-SW01-S9312>cd logfile<GDGZ-MA-IPMAN-FC-SW01-S9312>dirDirectory of cfcard:/logfile/Idx Attr Size(Byte) Date Time FileName0 -rw- 7,150,374 Jan 28 2011 14:17:00 log.txt1 -rw- 204,765 Jan 14 2011 18:18:58 2011-01-14.18-18-52.diag.zip2 -rw- 237,550 Jan 14 2011 17:59:48 2011-01-14.17-59-41.diag.zip3 -rw- 5,512,736 Jan 28 2011 13:45:54 diag.txt4 -rw- 251,281 Jan 05 2011 21:30:12 2011-01-05.21-30-08.log.zip5 -rw- 264,187 Jan 14 2011 18:01:14 2011-01-14.18-01-09.log.zip6 -rw- 230,136 Jan 14 2011 18:21:34 2011-01-14.18-21-29.log.zip7 -rw- 205,445 Jan 14 2011 18:38:14 2011-01-14.18-38-08.diag.zip8 -rw- 231,180 Jan 14 2011 18:41:52 2011-01-14.18-41-46.log.zip9 -rw- 204,397 Jan 14 2011 18:57:14 2011-01-14.18-57-07.diag.zip10 -rw- 230,535 Jan 14 2011 19:02:04 2011-01-14.19-02-00.log.zip11 -rw- 205,018 Jan 14 2011 19:16:24 2011-01-14.19-16-19.diag.zip12 -rw- 245,137 Jan 14 2011 19:22:28 2011-01-14.19-22-23.log.zip13 -rw- 206,074 Jan 14 2011 19:35:36 2011-01-14.19-35-32.diag.zip14 -rw- 231,134 Jan 14 2011 19:42:34 2011-01-14.19-42-28.log.zip（省略N行）500,192 KB total (415,904 KB free)<GDGZ-MA-IPMAN-FC-SW01-S9312>4、登陆城域网网管服务器，将9312交换机上的历史log文件先FTP下载到城域网网管服务器上。

在输入get命令前在输入bin是改变文件传送格式，避免下载后加压缩失败。
