Action
• Ensure that you have configured the agent with a valid IP
address, subnet mask and default gateway.
• If you are trying to connect to the agent via the IP address
for a tagged VLAN group, your management station must
include the appropriate tag in its transmitted frames.
• Check that you have a valid network connection to the
switch and that the port you are using has not been disabled.
• Check network cabling between the management station
and the switch.
• If you cannot connect using Telnet or SSH, you may have
exceeded the maximum number of concurrent Telnet/SSH
sessions permitted. Try connecting again at a later time.
• Ensure that you have set the terminal emulator program to
VT100 compatible, 8 data bits, 1 stop bit, no parity, and set
the baud rate 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.
