Catalyst configuration backups - some not working details here

[AidanEnos]

The one that fails:

WS-C5500 Software, Version McpSW: 6.1(2) NmpSW: 6.1(2)Copyright (c) 1995-2001 by Cisco SystemsNMP S/W compiled on Jan 26 2001, 20:02:58MCP S/W compiled on Jan 26 2001, 19:58:41

System Bootstrap Version: 3.1.2
Hardware Version: 1.3
Model: WS-C5500

The one that mostly (another issue entirely) works:

WS-C5500 Software, Version McpSW: 6.1(2) NmpSW: 6.1(2)Copyright (c) 1995-2001 by Cisco SystemsNMP S/W compiled on Jan 26 2001, 20:02:58MCP S/W compiled on Jan 26 2001, 19:58:41

System Bootstrap Version: 5.1(2)
Hardware Version: 1.4
Model: WS-C5500


What we are doing is:

snmp set tftp server
snmp set config name
snmp start tftp configuration upload

Do you think that the System bootstrap versions can be causing any tftp anomalies? I don't imagine it's the hardware and the configurations have all been compared - they have no real other issues.

I have manually backed-up all of the configs (we have 50 switches in total), and all work with a "write network", so we can see the server, we can tftp to it, we get good data - it simply fails through snmp initiated tftp.

Any thoughts?

Thanks,
