XMC failed to backup Avaya ERS switches via BOSS-SFTP script

[Rafael_Lopez]

When using the included "BOSS-SFTP" script to backup various recent builds of Avaya ERS switches, the backups fail to authenticate to XMC. I am not sure what credentials the script is using to authenticate to the XMC server or how to change it. I have tested an SFTP client from my PC to the XMC server using my and root credentials and I am able to get a session so I know XMC is listening. Here is syslog output from an ERS (10.33.20.10) running the script to connect to the XMC server (10.50.26.222) and failing to authenticate.

Hi guys,

regarding this article
https://extremeportal.force.com/ExtrArticleDetail?n=000035775&q=%3C%40-%20%25%20SFTP%20Filename%...

there is a 30-character limitation in the boss code for filename

the default boss-sftp script copies the file into /root/config/tmp/10_10_10_232/nms.xsf

boss interprets the whole string as filename, so its too long.

provided resolution is to upgrade the switches to the last release.

BUT
- there is no hint to this problem in the release notes
- in my case with last ers3600 release (6.2.0.57) the problem still exists

i hope extreme will release a fix soon

Hi! Backup of ERS3626 not possible, cause filename too long:

XMC serverlog:

ERS3626(config)#copy config sftp address 10.10.10.80 filename /root/configs/tmp/10_10_10_232/nms.xsf username user password
% SFTP Filename too long (max length 30).

Someone knows a solution?
Thanks in advance

Awesome! That was the trick, didn't know where this was. We are new to XMC but it is already making things easier than what we were doing before.

Thanks for pointing me to the right place.
