Appendix C Troubleshooting
Miscellaneous Problems
Defect Information—If file is available, but file is not ftp'd and FTPERR_550 exception is thrown, then
collect cwmftpd.log, cwmftpd.request_log and logs of the process for which files are not getting
transferred by cwmftpd and report the problem.
Possible alternative workaround—None
Related key index entries: file unavailable, ftperr_550, requested action not taken.
C.15.3.6 FTP Sessions in Switch
Switch allows only four ftp sessions. When cwmftpd makes a request to open a session, if the switch
cannot service the request because it has reached its session limit or if the file is locked, then it will
respond with a special error message "499 Session limit reached, queuing <IP address> key
<Nodename/XXXXXXXX>".
Key is a unique string for the node that is used later when the session is available. Cisco MGM waits on
a TCP Port 5120 for the switch to connect to. When a session is available, switch connects to the
pre-defined port and sends the [KEY] as data to Cisco MGM. Cisco MGM uses to <KEY> to identify
which switch it needs to open the session with. The session should now be opened without encountering
a failure and cwmftpd can proceed with the FTP request.
The switch will reserve the session for the Cisco MGM station for 30 seconds before it services other
stations. MGMftpd will retrieve multiple files within a single FTP session. A maximum limit per session
will be imposed.
This feature is supported in Cisco MGM 12 and above with MGX 8850 Release 4 and above. For SWSW
lower than MGX 8850 Release 4, switch will respond with "421 Session limit reached, closing control
connection".
The number of ftp sessions currently opened by switch can be determined by executing the switch
command, dsptasks. For each ftp session, 'dsptasks' output will have entry like following.
FtpdServ1 0x9a00a1 0x82d8a8a0
If there are two sessions, there will be two entries.
Related key index entries: switch ftp session
C.15.3.7 421 Session Limit Reached
For SWSW lower than MGX8850 Release 4, switch will respond with "421 Session limit reached,
closing control connection" , when it reached the limitation of four ftp sessions.
This is limitation on switch for SWSW lower than Release 4.
Step 1 Check whether really all four sessions are opened by opening a manual FTP session to switch or by
switch command - dsptasks.
Step 2 Check whether it succeeds.
Defect Information—If manually opening the FTP session succeeds or dsptasks command shows less
than four entries for 'FtpdServ', but still cwmftpd throws FTPERR_421, then report the problem with
cwmftpd.log, cwmftpd.request_log and logs of the process for which files are not getting transferred by
cwmftpd.
