Nortel Java Device Manager Tips
I hope the majority of folks out there can agree with me when I say that Nortel’s Java Device Manager was a large step up from Nortel’s Site Manager application. While I personally do the majority of my work in the CLI interface, Device Manager is a very useful tool to have around.
I really like the fact that you can launch either a telnet or SSH session straight from Device Manager. Over the years I’ve found PuTTY to be the best terminal application so I configured Device Manager to call PuTTY for telnet and SSH connections.
After opening Device Manager select Device -> Properties -> Current. Select “User-Defined” for both Telnet and SSH and then place “C:\Program Files\PuTTY\putty.exe” (or wherever you have PuTTY installed) into option box and then use “-telnet <ip>” for telnet sessions and “-ssh <ip>” for SSH sessions (see figure above).
Another problem you can sometimes run into with Device Manager is the relative easy with which you can mistakenly delete a row (interface, VLAN, ACL, etc). Thankfully there is an option within JDM that you can enable called “Confirm row deletion” (see figure above).
Cheers!

v3.2 SSH Secure Shell is still freely available on various FTP sites—mostly universities I believe. Its another very good alternative to the built-in JDM defaults. Of course we don’t use telnet anymore though, do we? :)
FYI, though: JDM will probably not get much, if any future development. I believe v6.0 of ERS 5xxx software is sporting a new web-interface and I think the 4500 code is supposed to quickly follow (if it hasn’t already). The ‘new’ Nortel probably can’t afford the resources that JDM support demands. Hi Mike,
I just have a personal preference for PuTTY, but as you pointed out there are a number of different solutions available.
You are correct in your comments about Device Manager. I understand from Nortel that there will be a new type of “Element Manager” that will run directly from the switch. I understand it will be introduced with Nortel’s new VSP 9000 switch sometime in January 2010.
Cheers!
Hi Gabe,
I use Enterprise Switch Manager from time to time. We have a standard DNS (FQDN) naming convention for our switches that makes it pretty easy to just open Device Manager and type in the FQDN of the switch you wish to manage. I’ve also written a lot of Perl scripts to that retrieve and correlate a lot of the information provided by ESM. This was of course before ESM was available or could perform that function.
I believe Enterprise Switch Manager v6.3.0 was just released on March 23, 2009. The release notes indicated support for SMLT/SLT environments and integration with CLI*Manager.
Thanks for the comment!

Hi Peter,
If you have the switch already in your previously opened list of switches you can just append the switch name on the end of the JDM call. Here are all the parameters as of release 6.2.0.
<host> -out -trace {sd} -rd <cmty> -wr <cmty> -trapPort <num> -trapLog <boolean> -sysLog <boolean> -socket <num> -proxy <file> -cacheServer <host>
You should find a .bat file in C:\Program Files\Nortel\JDM which you can adopt to help you test. I marked up the .bat file like so;
@echo off echo Launching Java Device Manager ... SET JDM_HOME=C:\Program Files\Nortel\JDM SET javaCmd=%JDM_HOME%\jre\bin\java SET READONLY=public SET READWRITE=private SET HOST=sw-5530.dc.acme.org "%javaCmd%" -Xmx256m -DEMPATH="%JDM_HOME%" -jar "%JDM_HOME%jdm.jar" %HOST% -rd %READONLY% -wr %READWRITE% @echo on
Good Luck!

Also I just found that you can change all the passwords of all the switches at one time on my entire network with the Security Manager in ESM.
Start the Enterprise Switch Manager Software
Click on Tools
Click on Security ManagerIn Security Manager
Double Click on SSHClick on the “+”
Enter a Group Name
Click button for the Ethernet Switch, Ethernet Routing Switches
Click All
Click OKEnter the SNMPv3 information
Click on Apply Changes
Click on the Change Passwords Tab
Enter the RWA User – This should be RW (uppercase)
Enter the current passwordEnter the New RW Password
Enter the New RO PasswordNote: The RW password for a switch and for a stack should be the same, and the RO password for the switch and the stack should be the same.
Click Change Password.
Click OK
Click Yes
Be Patient!! This will take about a half hour for 500 switches.
Look at the log file –
You should see the following****************************************************************************************************
2009/01/28-18:35:10 : User : labConnecting 192.168.10.105 …

Etc….Now test your passwords
Done!

I found today that if you edit the JDM.BAT file to have a %1 at the end of the command line in the batch file, you can just call JDM.BAT followed by the Ip or hostname .
—
echo Launching Java Device Manager …
SET JDM_HOME=C:\Program Files\Nortel\JDM
SET javaCmd=%JDM_HOME%\jre\bin\java“%javaCmd%” -Xmx256m -DEMPATH=”%JDM_HOME%” -jar “%JDM_HOME%jdm.jar” %1
@echo on
—You can place jdm.bat anywhere in your path, or call it explicitly from an external application.
Personally, I use PRTG from http://www.paessler.com to measure my network devices, and JDM to manage them.

I will warn you to be careful you don’t lock yourself out.
Here are the commands to reset your read/write community strings for the ERS8600 to “lock” and “open”. The default SNMP strings are public (first) and private (second) you can reconfigure those with the following two commands;
ERS-8610:5# config snmp-v3 community commname first new-commname open
ERS-8610:5# config snmp-v3 community commname second new-commname lockThe commands from the ERS4500 are slightly different but here are those commands;
5520-48T-PWR (config)# snmp-server community open ro
5520-48T-PWR (config)# snmp-server community lock rwGood Luck!

Hello!
These topics are best discussed on the forums, http://forums.networkinfrastructure.info/ but I’ll help answer them here as well.
The configuration for Nortel’s Java Device Manager is stored in XML files which are located in the user’s $HOME directory under a hidden folder called ‘jdm’.
Windows XP; C:\Documents and Settings\Michael\jdm
Windows Vista; C:\Users\Michael\jdmYou’ll be looking for two files; dm.xml and dm_devices.xml.
You can find additional information in this post.
Good Luck!

Hello to all
I use ESM 6.3.0 and i want have a estadistics of the cpu consuption.
With JDM i can viewing CpuUtil(%) a graphic from performnace in real time but only with window de 3 min and 20 seg.Somebody knows how can capture data of the window JDM,”Graph Chasis System, CpuUtil”? For playback on a graphic historic the performance of the CPU.

Hi Thallium,
The answer is going to depend on a number of variables include what model of switch and what software release. The last time I looked authenticating SNMPv3 sessions via RADIUS/TACACS+ was not yet supported on the Ethernet Routing Switch 8600, 5000,4500,2500.
I’m not sure but I would be surprised if this is not supported in software release 7.0 for the ERS 8600.
I would suggest you have a look at the document below. It may be slightly dated but it should provide you enough information to get you started.

I have two Noretl ERS 8600 (R Module) with IST and VRRP configured.I have 20 vlan (from Vlan 1 to Vlan 20) having IP 172.16.1.0 to 172.16.20.255.
i.e Vlan 1- 172.16.1.0-172.16.1.255,
Vlan 2- 172.16.2.0 -172.16.2.255,
and so on…I wants Vlan 15 should communicate only with 172.16.16.11. & block all other connection from Vlan 15.
Guide me configure with device manager and CLI
Hi Ashok,
Your question isn’t really topic for the post “Nortel Java Device Manager Tips”. You need to investigate traffic filters. You can post your question over in the discussion forums and I’m sure someone will respond.
Cheers!

Hi All:
I am having a problem let say with the JDM each tim ethat I launch the application it shows me a window that says. “YOU ARE ATTEMPTING TO USE AN OLDER VERSION OF JDM CODE WITH A NEWER VERSION OF SOFTWARE CODE FOR THIS DEVICE YOU ARE MANAGING. PLEASE VISIT NORTEL.COM TO GET LATEST JDM SOFTWARE”. but I am using the version 6.2.1.3 that it is suppose that is the latest one. Can any one help me to solve this?
Regards

That’s a different model of switch and has a different OID. I should also warn you that the SNMP OID for CPU and memory utilization is only available when running 6.x software on the ERS 5000 series switch. I don’t recall the exaxt OID right now but you can find it by performing a packet trace of Device Manager, Edit -> Chassis -> Chassis -> CPU/Mem Utilization. I believe it’s somewhere around 1.3.6.1.4.1.45.1.6.3.8.1.1.x
Good Luck!
