Cannot connect using

Telnet, web browser,

or SNMP software

• Be sure the switch is powered up.

• Check network cabling between the management station and the

switch.

• Check that you have a valid network connection to the switch and

that the port you are using has not been disabled.

• 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.

• Be sure the management station has an IP address in the same

subnet as the switch’s IP interface to which it is connected.

• If you are trying to connect to the switch via the IP address for a

tagged VLAN group, your management station, and the ports

connecting intermediate switches in the network, must be

configured with the appropriate tag.

• If you cannot connect using Telnet, you may have exceeded the

maximum number of concurrent Telnet/SSH sessions permitted.

Try connecting again at a later time.
