I have a number of 2950s on a remote site I am trying to upgrade via CNA - the .tar file is on a TFTP server at the remote site, and CNA is running on a PC at the local site, with a VPN connection between the two sites
2950+----<--VPN-->Local CNA PC
The TFTP server is on the same subnet as the VLAN interface on the 2950.
However, when I try to use CNA to perform the upgrade, the upgrade fails, with the following messages in the status window:
Uploading the image
Extracting the info file from the image
Software upgrade failed
I have run a packet capture on the remote network and there is no TFTP traffic between the switch and the TFTP server. Does CNA support upgrades in this environment? I can access the image on the TFTP server via command line on the remote switch, but as I have a large number of switches across multiple sites, I was hoping to use CNA to ease the upgrade process as far as possible.
There is a 'details' button that may provide more information on what's going wrong. I had some 2950s that failed upgrades, it turned out to be a lack of memory ... deleting the old firmware solved the problem. This may or may not be your problem, but in my case the problem became obvious after reading the 'details'.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
