The community strings configured for the system and Network Manager are the same.
The SNMPv3 USM, Auth, and VACM configured for the system and Network Manager are the
same.
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.
You entered the IP address of the switch correctly when invoking the Telnet facility.
Telnet access is enabled 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 for the system.
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.
The port through which you are trying to access the device is in a correctly configured Virtual LAN
(VLAN).
The community strings configured for the device and the Network Manager are the same.
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 from accessing the device over the network. Try accessing
the device through the console port.
Permanent entries remain in the FDB:
If you have made a permanent entry in the FDB that requires you to specify the VLAN to which the
entry belongs and then deleted the VLAN, the FDB entry remains. Although this does not harm the
system, if you want to removed the entry, you must manually delete it from the FDB.
Default and static routes:
If you have defined static or default routes, those routes 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.
