Symptom
Action
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.
Cannot connect using
Secure Shell
◆
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 both an RSA and DSA public key
on the switch, exported this key to the SSH client, and enabled
SSH service.
◆
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).
Cannot access the on-
board configuration
program via a serial port
connection
◆
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 115200 bps.
◆
Check that the null-modem serial cable conforms to the pin-out
connections provided in the Installation Guide.
Forgot or lost the
password
◆
Contact your local distributor.
