Traps are not received by the SNMP Network Manager:
Check that the SNMP Network Manager's IP address and community string are
correctly conÞgured, and that the IP address of the Trap Receiver is conÞgured properly
on the Switch.
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
conÞgured 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 conÞgured for the Switch and the Network Manager
are the same.
Check that SNMP access was not disabled for the Switch.
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 deÞned static or default routes, those routes will remain in the
conÞguration 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.
