Chapter 2. Message and Recovery Procedures

This section contains the Dynamic Trunking Protocol (DTP) messages.

Explanation This message means that the system is unable to negotiate trunks because of a lack of 
memory.

Reduce other system activity to ease the memory demands. 

DTP-4-TMRERR: An internal timer error occurred when trunking on interface [chars].

Explanation This message means that a timer used by the trunking protocol unexpectedly expired. 
[chars] is the trunked interface.

This error is internally corrected, and no long-term ramifications exist. However, if more 

problems with trunking occur, reload the switch by using the reload privileged EXEC command.

Explanation This message means that the system is unable to negotiate trunks because an internal 
operation generated an unexpected error.

Reload the switch by using the reload privileged EXEC command.

DTP-5-ILGLCFG: Illegal config (on, isl--on, dot1q) on [chars].

Explanation This message means that one end of the trunk is configured as 

, 

, and the other end 

is configured as 

, 

. [chars] is the interface.

This configuration is illegal and will not establish a trunk between two switches. You must 

change the encapsulation type so that both ends of the trunk match.

DTP-5-NONTRUNKPORTON: Port [chars] has become non-trunk.

Explanation This message means that the interface changed from trunk to access. [chars] is the 
interface that changed.

This message is provided for information only.

DTP-5-TRUNKPORTCHG: Port [chars] has changed from [chars] trunk to [chars] trunk.

Explanation This message means that the encapsulation type of the trunk has changed. The first [chars] 
is the interface, the second [chars] is the original encapsulation type, and the third [chars] is the new 
encapsulation type.
