It’s been a while since I’ve posted anything on my website. I had a crazy year, had a lot of work that ruined all my plans to study a lot. Hopefully it’s now sorted with my management and next year is promised to be much better from the work/life/study balance perspective. I know I wasn’t a best webmaster and didn’t respond to many of your comments – I promise I will improve and reply to all comments in the coming weeks. I am going for WISECURE exam in less than two weeks from now, so wish me luck.
In the meanwhile, I’d like to share an undocumented feature of Cisco Prime (well, at least I wasn’t able to find any guidelines on that in Cisco Prime documentation). I have recently configured Prime for images archiving, but few days later realized that it fails to copy images from Catalyst 3850 switches. All transfer modes have been failing – FTP, SFTP, SCP and TFTP. There are no settings in Prime that relate to SCP and SFTP (you can only enable/disable FTP and TFTP servers). I’ve done some research and found that for SCP downloads Prime is acting as a client. Therefore, Catalyst 3850/3650 switches must be SCP servers.
To enable SCP server on Catalyst 3850/3650 execute the following global configuration command:
ip scp server enable
Once applied, Prime will be able to archive IOS-XE images from Catalyst 3850/3650s. However, there is restriction. Cisco Prime cannot archive an image from Catalyst 3850 if it was installed using INSTALL mode. That is, when BIN package is unpacked into few separate files. Only BUNDLE mode is supported for archiving. Not great huh? Cisco does not recommend to use BUNDLE mode for image distribution on Catalyst 3850s, but at the same time Cisco Prime can’t archive image if it was distributed using recommended INSTALL mode.
Cisco is so Cisco…
