[c-nsp] Problem with interface

[john doe]

Hi


I have a problem with a 6506 with WS-SUP720-3BXL SUP and the line card in
question is WS-X6704-10GE. Only port 4 port is in use and it’s running
mols, TE, BGP (no full table) and so on. Port 4 is connected via multimode
to a switch that is intermediate device to another router.


Everything seems to work fine when traffic levels is 1-1.5Gbps, when
pushing above that the port goes down on the 6500 and comes right back up
again.


I can’t find any clues on what is going on. No errors to talk about, optics
looks good and so on.


Any ideas?

Johan
