Can't archive nexus 5010 configs (LMS 3.2)

IGOR SPANZ
Level 1
Level 1

Using LMS 3.2 I can't archive configs from

our Nexus 5010 ( 4.2(1)N1(1) ) devices . I have installed

the   necessary device package Nexus.RME431.v2-4.zip. Following error occures:

*** Device Details for                          gf02na50050p                         ***
Protocol ==>                          Unknown / Not Applicable
Selected Protocols with order ==>                                                                                  SSH,SCP,TFTP,RCP,Telnet

Action: Check if protocol is  supported by device and required device package is installed. Check  device credentials. Increase timeout value, if required.

Telnet on device is disabled, SSH enabled.

with only SSH on RME   followig error:

It doesn't look like you re-ran the job and reproduced the error.  With debugging enabled, you need to reproduce the error you're seeing when trying to fetch the 5010 config.

What version of the Nexus RME package do you have loaded?  Version 2.4 contains support for the Nexus 5010 switches.

I have version 2.4.

On the Nexus Telnet is not permitted (as soon as I permit Telnet on Nexus - functioned everything), however, the Ciscoworks goes only with Telnet or TFTP on Nexus 5010 Device, on Nexus  7000 functions with SSH!!!

Enable ArchiveMgmt Service debugging under RME > Admin > System Preferences > Application Loglevel Settings, then re-run the job.  Post the dcmaservice.log.

I have the file postet

I have made it once more. Enclosed the log files

can you find in log what?

Hi All,

I have the same problem here,

LMS 3.2 Fresh Install, all device packages updated today (RME,CMS,DFM,CM).

Transport protocol is set to SSH only.

Nexus 5010 is running 4.1(3)N2(1a)

I attached my log file containing the archive job debug only.

One thing I noticed is that ciscowrks tries these two commands:

  1. terminal length 0
  2. terminal width 512

The second command dosen't seem to be support by the NXOS "Invalid number range (24:511)" is returned by the CLI when I try.

I don't know if this can help but I tried ....

For me it looks like as a bug in the ssh implementation in RME, but I cannot find a bug id on CCO ....

Martin, please start a new thread for your issue.

finally I got this answer from Joseph Clarke  which resolved the issue:

https://supportforums.cisco.com/message/3176796#3176796

1.  Sep 8, 2010 6:23 AM  in response to: mermel
Re: RME 4.3.1 (windows); unable to archive config of Nexus 5020 with ssh

Actually, this is a timing issue, and it's easily fixed without a patch.  In LMS 3.2, we now provide a user-editable cmdsvc.properties file under NMSROOT/objects/cmf/data.  Edit this file, and change TuneSleepMillis to 500 or 1000 (you'll need to uncomment this).  Then restart ConfigMgmtServer:

pdterm ConfigMgmtServer
pdexec ConfigMgmtServer

That should fix this problem.


and I also found this:
Note: one should also consider BugId CSCte98853 for Nexus configuration archive

==============================================
CSCte98853 Bug Details     
RME cannot archive configs for NEXUS 5000 and 7000 devices
Symptom:

RME 4.3 doc says NEXUS 5000/7000 are all supported, but automated actions for config archives do not work. This is because the NEXUS devices use a different form of syslog format:

"%VSHD-5-VSHD_SYSLOG_CONFIG_I:"

RME's existing Config_Fetch automated action should add this syslog in the future versions.


Conditions:

This affects all RME versions up to 4.3.1.


Workaround:

Steps to add the message format:

a) Navigate to Tools --> Syslog --> Automated Actions
b) Select the "Config Fetch" and click on edit
c) Don't change on the next screen. Click "next" to proceed to
"Define Message Type" wizard
d) Click on "Add" button then fill the following details as follows:

a. Facility - VSHD
b. Sub-facility - *
c. Severity - 5
d. Mnemonic - VSHD_SYSLOG_CONFIG_I
e. Description - *

Then restart the SyslogAnalyzer daemon
==========================================================================

Hi all,

I can confirm that this workaround worked for me !!

Thank's very much for the tip !!

Best regards
