I was trying to set up tftp server on a 2514 for IOS upgrade and found that on the same 2514 platform with 14MB RAM and 16MB flash. I ran into problems with IOS 12.3(5). Here are the observatios:
1) When 12.1(20) is running,
Router(config)#tftp-server ?
flash: Allow URL file TFTP load requests
flh: Allow URL file TFTP load requests
lex: Allow URL file TFTP load requests
null: Allow URL file TFTP load requests
nvram: Allow URL file TFTP load requests
system: Allow URL file TFTP load requests
2) when 12.3(5) is running,
Router-A(config)#tftp-server ?
null: Allow URL file TFTP load requests
nvram: Allow URL file TFTP load requests
system: Allow URL file TFTP load requests
Router and Router-A are the same exact model with same amount of RAM and flash.
3) on Router-A with c2500-i-l.123-5.bin, I tried "tftp-server system:\flash:c2500-is-l.123-5a.bin", which did not give me "file not found" error. But when I tried to connect to it from the target c2514 (in BootRom after changing to 0x2101), it always failed to load the image. I think it's because I couldn't do "tftp-server flash:\..."
Why does 12.1 have more tftp-server options than 12.3?
4) "show flash" works in 12.1 but not in 12.3. I could only "dir" to show the image in 12.3. "show file system" won't show the details. Is there an eqivilent of "show flash" in 12.3?
Thanks!
