Action
• If you cannot connect using SSH, you may have exceeded the
maximum number of concurrent Telnet/SSH sessions permitted.
Try connecting again at a later time.
• Be sure the control parameters for the SSH server are properly
configured on the switch, and that the SSH client software is
properly configured on the management station.
• Be sure you have generated a public key on the switch, and
exported this key to the SSH client.
• Be sure you have set up an account on the switch for each SSH
user, including user name, authentication level, and password.
• Be sure you have imported the client's public key to the switch (if
public key authentication is used).
• Be sure you have set the terminal emulator program to VT100
compatible, 8 data bits, 1 stop bit, no parity, and the baud rate set
to any of the following (9600, 19200, 38400, 57600, 115200 bps).
• Check that the null-modem serial cable conforms to the pin-out
connections provided in the Installation Guide.
• Contact SMC Technical Support for help.
