Cannot connect using

or SNMP software
Be sure you have configured the VLAN interface through which the
management station is connected with a valid IP address, subnet mask
and default gateway.
If you are trying to connect to the switch via the IP addre ss 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.
