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 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).
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.
