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.
5. For messages that indicate that the number of MAC address entries for the VLAN exceeds the
maximum number allowed, have your system administrator configure an action.
6. For messages that indicate that an unauthorized device attempted to connect on a secure port, identify
the device that attempted to connect on the secure port and notify your network system administrator of
the condition.
7. For messages that indicate that the amount of traffic detected on the interface has exceeded the
configured threshold values, determine and fix the root cause of the excessive traffic on the interface.
8. For messages that indicate an unrecoverable software error has occurred, copy the message exactly
as it appears on the console or in the system log and contact TN Support.
See “LIB-4xxx Error Recovery” on page 44 for specific messages and the recommended recovery steps.
