S4224 Error Recovery
The S4224 displays error and information messages from the CLI and Web interface. This section lists
the messages, provides an example, and discusses the message meaning of and possible recovery
steps.
As a general troubleshooting step for problems encountered using the S4224 web interface, try the
related CLI command. For many messages, recovery involves reviewing the command/function
description and verifying the entry selection/syntax. For example, for many CLI messages, the first
recovery step would be to refer to the “S4224 CLI Reference Guide” manual.
For any error condition, you can check the
site for possible solutions. For any
problem that persists, contact TN Tech Support in the US or Canada at 1-800-260-1312, International at

Generic Message Recovery (e.g., you tried a function, but the operation failed or is still in process):
1. Wait for a few moments for the operation to complete.
2. Use the
Help
or
?
command to get assistance (help) on a group of commands or on a specific
command.
3. Make sure this is the function you want and that the device/port/configuration supports this function.
4. Verify the parameters entered and re-try the function. See the related section of this manual for
specifics.
5. Try using the CLI to perform the function. Refer to the “S4224 CLI Reference Guide” manual.
6. If the “continue
y
(es)
n
(o) prompt” displays, type
y
and press
Enter
to continue.
7. Use the
sub-menu functions (System, Ports, Link OAM, MAC Table, VLANS) to view related
status, statistics, events, etc. related to a specific function.
8. Use the
sub-menu functions (Ping, Link OAM MIB Retrieval, VeriPHY) to test
a general functionality.
9. Use the
sub-menu functions (Restart the S4224, Reset the S4224 to factory
defaults, Upgrade the S4224 firmware).

Specific Messages Recovery:
1. For messages (e.g., ACL messages) that are the result of a switch memory shortage:
a. Reduce other system activity to ease memory demands.
b. Use a less complicated configuration that requires less memory.
c. Modify the ACL configuration to use fewer resources, or rename the ACL with a name or number
that alphanumerically precedes the other ACL names or numbers.
d Reduce the number of IP or MAC access lists to be applied to interfaces.
e. Reduce other system activity to ease memory demands (e.g., remove ACLs that are defined but
not used; use simpler ACLs with fewer ACEs; use fewer VLANs / remove unneeded VLANs from
the VLAN database).
2. For messages that indicate the configuration is too complicated for the ACL code to support, there is
likely too many separate access lists in a single VLAN map or policy map. Reduce the number of IP
or MAC access lists separately) in any one VLAN or policy map to fewer than the number of levels.
Or try to use the same ACLs on multiple interfaces if possible.
3. For messages that indicate an illegal configuration, reconfigure the port / device, removing the illegal
configuration.
4. For messages that indicate the temperature is high reduce the temperature in the room.
