本文档提供了如何将网络分析模块(NAM)软件升级到3.x版的分步过程。
尝试进行此配置之前,请确保满足以下要求:
熟悉文件传输协议(FTP)
熟悉命令行中的Catalyst交换机管理
本文档中的信息基于以下软件和硬件版本:
WS-X6380(原始NAM)
NAM 3.0版软件
NAM-1和NAM-2硬件设备
运行CatOS 7.3.1的Catalyst 6505
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您使用的是真实网络,请确保您已经了解所有命令的潜在影响。
有关文档规则的详细信息,请参阅 Cisco 技术提示规则。
本节介绍将NAM软件升级到3.x版的信息。
要升级软件,请完成以下步骤:
下载文件:
原始NAM — 请参阅适用于Cat 6500的软件下载NAM(生产代码:WS-X6380-NAM)(仅注册客户),并获取c6nam.3-1-1.bin.gz文件。
NAM1/NAM2 — 请参阅适用于Cat 6500的软件下载NAM(生产代码:WS-SVC-NAMx)(仅注册客户),并获取c6svc-nam.3-1-1.bin.gz文件。
将文件放在要使用的FTP服务器上帐户的根目录中。
注意:此图示使用WS-X6380-NAM,但同时适用于WS-SVC-NAM-1和WS-SVC-NAM-2。
本示例使用以下信息:
FTP服务器是:
名称:rtp-sycamore.cisco.com
地址 :172.18.123.68
帐户ID为cse。
帐户密码为csec。
cse的根目录为:~ rtp-sycamore cse %4> pwd /local/home/cse。
文件列在此处,因此:/local/home/cse/c6nam.3-1-1.bin.gz。
~ rtp-sycamore cse %4>ls -al c6nam.3-1-1.bin.gz-rw-r—r— 1 cse other 75671244 5月28日11:17 c6nam.3-1-1.bin.gz
要验证FTP服务器是否正常工作,请测试以查看此FTP服务器是否可从另一台工作站访问:
注意:此处使用rtp-cse-205作为示例。
rtp-cse-205_oansari-> ftp rtp-sycamore Connected to rtp-sycamore.cisco.com. 220 rtp-sycamore FTP server (SunOS 5.7) ready. Name (rtp-sycamore:oansari): cse 331 Password required for cse. Password: csecse 230 User cse logged in. Remote system type is UNIX. Using binary mode to transfer files.
当您访问FTP服务器时,请确保文件可用:
ftp> ls c6nam.3-1-1.bin.gz 227 Entering Passive Mode (172,18,123,68,222,205) 150 ASCII data connection for /bin/ls (64.102.51.64,35372) (0 bytes). -rw-r--r-- 1 cse other 75671244 May 28 11:17 c6nam.3-1-1.bin.gz 226 ASCII Transfer complete.
当您验证文件存在且可用时,您会更加确信文件传输到NAM将成功。这确认FTP服务正在运行,且所需文件可下载到FTP客户端。
开始升级NAM的步骤。示例如下:
检查模块:
nms-6506a> (enable) sh mod ... Mod Slot Ports Module-Type Model Sub Status --- ---- ----- ------------------------- ------------------- --- -------- 1 1 2 1000BaseX Supervisor WS-X6K-SUP1A-2GE yes ok 15 1 1 Multilayer Switch Feature WS-F6K-MSFC no ok 2 2 0 FlexWAN Module WS-X6182-2PA no power-down 4 4 2 Network Analysis Module WS-X6380-NAM no ok 5 5 8 1000BaseX Ethernet WS-X6408-GBIC no ok 6 6 48 10/100BaseTX Ethernet WS-X6348-RJ-45 yes ok
输出显示,所关注的NAM位于插槽4中,状态为ok。
检查CatOS交换机的版本:
nms-6506a> (enable) sh ver WS-C6506 Software, Version NmpSW: 7.3(1)
注意:版本必须是7.3(1)或更高版本。如果您的交换机未升级到此版本,请勿继续升级NAM。首先升级交换机软件。
如果指示的版本为7.3(1)或更高版本,则重置NAM:
nms-6506a> (enable) reset 4 hdd:2 This command will reset module 4. Unsaved configuration on module 4 will be lost Do you want to continue (y/n) [n]? y Module 4 shut down in progress, do not remove module until shutdown completed. nms-6506a> (enable)
注意:对于NAM1/NAM2,必须使用以下命令:reset <module> cf:1。
您在终端上看到以下输出:
2003 May 28 11:28:36 %SNMP-5-ENTITYMODTRAP:Module 4 status changed to "unknown(1)" 2003 May 28 11:28:36 %SNMP-5-MODULETRAP:Module 4 [Down] Trap 2003 May 28 11:28:36 %SNMP-5-ENTITYMODTRAP:Module 4 status changed to "failed(7)" 003 May 28 11:28:50 %SNMP-5-FRUREMOVEDTRAP:module 4 removed 2003 May 28 11:28:50 %SNMP-5-ENTITYTRAP:Entity Mib last change time 483090709 ticks 2003 May 28 11:28:50 %SNMP-5-ENTITYMODTRAP:Module 4 status changed to "unknown(1)" 2003 May 28 11:29:07 %SNMP-5-ENTITYTRAP:Entity Mib last change time 483092362 ticks 2003 May 28 11:29:07 %SNMP-5-FRUINSERTEDTRAP:module 4 inserted 2003 May 28 11:30:26 %SNMP-5-ENTITYMODTRAP:Module 4 status changed to "ok(2)" 2003 May 28 11:30:26 %SNMP-5-MODULETRAP:Module 4 [Up] Trap 2003 May 28 11:30:27 %SNMP-5-FRUREMOVEDTRAP:module 4 removed 2003 May 28 11:30:27 %SNMP-5-ENTITYTRAP:Entity Mib last change time 483100353 ticks 2003 May 28 11:30:27 %SNMP-5-FRUINSERTEDTRAP:module 4 inserted 2003 May 28 11:30:27 %SYS-3-MOD_PORTINTFINSYNC:Port Interface in sync for Module 4
确保NAM重新启动成功:
