DTP Messages
Error Message DTP-4-TMRERR: An internal timer error occurred when trunking on
interface [chars].
Explanation A timer used by the trunking protocol unexpectedly expired. [chars] is the trunked
interface.
Recommended Action This problem is corrected internally and has no long-term ramifications.
However, if more problems with trunking occur, reload the switch by using the reload privileged
EXEC command.
Error Message DTP-4-UNKN_ERR: An unknown operational error occurred.
Explanation The system cannot negotiate trunks because an internal operation generated an
unexpected error.
Recommended Action Reload the switch by using the reload privileged EXEC command.
Error Message DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port
[chars] because of VTP domain mismatch.
Explanation The two ports in the trunk negotiation belong to different VTP domains. Trunking can
be configured only when the ports belong to the same VTP domain. [chars] is the port number.
Recommended Action Ensure that the ports in the trunk negotiation belong to the same VTP domain.
Error Message DTP-5-ILGLCFG: Illegal config (on, isl--on,dot1q) on [chars].
Explanation One end of the trunk link is configured as on with ISL encapsulation and that the other
end is configured as on with 802.1Q encapsulation. [chars] is the interface.
Recommended Action 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.
Error Message DTP-5-NONTRUNKPORTON: Port [chars] has become non-trunk.
Explanation The interface changed from a trunk port to an access port. [chars] is the interface that
changed.
Recommended Action This message is provided only for information.
Error Message DTP-5-TRUNKPORTCHG: Port [chars] has changed from [chars] trunk to
[chars] trunk.
Explanation The encapsulation type of the trunk port 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.
Recommended Action This message is provided only for information.
