I'm trying to setup a trunk link between 2 3750G-16TD's using the TenGig interface.
The interfaces are configured as per any other trunk, however as soon as we cable to 2 devices up the interface immediately goes into err-disable;
Aug 14 18:54:58.501: %PM-4-ERR_DISABLE: link-flap error detected on Te1/0/1, putting Te1/0/1 in err-disable state
We have tried several different cables and configs.
Question is - is there any special config required to enable trunking using the TenGig interfaces???
Thanks in advance,
