The Telnet workstation cannot access the device:
Check that the device IP address, subnet mask and default router are correctly configured, and that the
device has been reset. Ensure that you enter the IP address of the switch correctly when invoking the
Telnet facility. Check that Telnet access was not disabled for the switch. If you attempt to log in and the
maximum number of Telnet sessions are being used, you should receive an error message indicating so.
Traps are not received by the SNMP Network Manager:
Check that the SNMP Network Manager’s IP address and community string are correctly configured,
and that the IP address of the Trap Receiver is configured properly on the system.
The SNMP Network Manager or Telnet workstation can no longer access the device:
Check that Telnet access or SNMP access is enabled.
Check that the port through which you are trying to access the device has not been disabled. If it is
enabled, check the connections and network cabling at the port.
Check that the port through which you are trying to access the device is in a correctly configured
VLAN.
Try accessing the device through a different port. If you can now access the device, a problem with the
original port is indicated. Re-examine the connections and cabling.
A network problem may be preventing you accessing the device over the network. Try accessing the
device through the console port.
Check that the community strings configured for the device and the Network Manager are the same.
Check that SNMP access was not disabled for the system.
Permanent entries remain in the FDB:
If you have made a permanent entry in the FDB (which requires you to specify the VLAN to which it
belongs and then delete the VLAN), the FDB entry will remain. Though causing no harm, you must
manually delete the entry from the FDB if you want to remove it.
Default and Static Routes:
If you have defined static or default routes, those routes will remain in the configuration independent of
whether the VLAN and VLAN IP address that used them remains. You should manually delete the
routes if no VLAN IP address is capable of using them.
You forget your password and cannot log in:
If you are not an administrator, another user having administrator access level can log in, delete your
user name, and create a new user name for you, with a new password.
Alternatively, another user having administrator access level can log in and initialize the device. This
will return all configuration information (including passwords) to the initial values.
In the case where no one knows a password for an administrator level user, contact your supplier.
