Hi, I have two sites located approximately 5kms apart, they have 72 core SMOF connected between locations. I have a 6509 at the core and a 3650E at the remote, both have GLC-LH-SM SPFs. The interface at the 6509 is not connectedThe interface at the 3560E is UP UP If I shut the 6509 interface, the 3560E goes DOWN DOWN All SFPs have been used previously, I have looped both ends and confirm that the interfaces come UP UP.I have confirmed the TX and RX paths and they are correct. Any suggestions? Dan
Does the following issue relate to the equipment you are running? The Link Does Not Come Up in the Sup720 Module with Line Cards WS-X6724-SFP and WS-X6748-SFP, Even After a Reboot<http://www.cisco.com/en/US/products/hw/ ... l#trouble1> You might also review the following document: Troubleshooting Switch Port and Interface Problems<http://www.cisco.com/en/US/products/hw/ ... bfd6.shtml>
Baileyshbr, Our switch configuration is different to the modules indicated in the links you provided, but this put me on the right track. I read through the document and when back in and shut the gigabit interface and then set the speed nonnegotiate command (again). waited, then no shut the interface and it has come up. Thanks. Dan
