nope, works great, in fact I have a LACP connection of 4x 10gbE runs from a 6610 to an LB6M:
Code:
telnet@LB6M#sh int br e 9 to 12
Port Link State Dupl Speed Trunk Tag Pvid Pri MAC Name
9 Up Forward Full 10G 9 No 1 0 54ab.3a41.d11a
10 Up Forward Full 10G 9 No 1 0 54ab.3a41.d11a
11 Up Forward Full 10G 9 No 1 0 54ab.3a41.d11a
12 Up Forward Full 10G 9 No 1 0 54ab.3a41.d11a
What do you mean by "module"? Are you using DAC's or optics? Also, have you set the 6610 SFP+ ports to 10gbE? By default they run at 1gbE, which obviously won't link with the LB6M, but will link with itself. To run them at 10gbE, you need to import a valid 10gbE license, then tell them to run at 10gbE in the 6610 config:
Code:
conf t
int eth 1/3/1 to 1/3/8
speed-duplex 10g-full
#if the switch pauses after this for a minute, it's normal
write mem
