Help configuring 3750 TenGig ports

Unanswered Question
Aug 14th, 2010

Hi,

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,

Iaqn

I have this problem too.

Hello,

The error disable is due to link issue. If the interface flaps beyond

threshold, the switch will errdisable the port. This seems purely a Physical

Layer issue. Can you please check the fiber and make sure that it is good?

Also, if you have any patch panels along the path, I would suggest bypassing

them to see if they are causing the issue.
