I recently setup all my 1924, 2924, 5009, and 6509's to be in trunk mode so I can setup Vlan's. Everything worked fine at first but now just my 1924's are having a problem. Some of them will loose the trunk connection to the 2924, 5009, or 6509 port, but not all of them. The other side of the trunk still shows the link as being up but I can't connect or ping the 1924. I have tried putting the 1924 in nonegotiate so it wouldn't pass DISL frames, but that seemed to have no effect.
If I go and reboot the 1924 it will come back up but will eventually go back down. I have tried everything I can think of. Thanks
