Explanation This message means that the system is unable to negotiate trunks because of a lack of memory. Recommended Action Reduce other system activity to ease memory demands. Error Message 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. 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.
