I have problem with optical link between core and WAN segments.
Here is situation:
I use Catalyst 3750E(ver c3750e-universal-mz.122-52.SE) as core switch and Catalyst 6504E(ver adventerprisek9_wan-vz.122-33.SXI6) as WAN switch. After changing optical transceiver from sfp 1000BaseLH to X2 10G 10Gbase-ER in syslog I found this:
%SFF8472-5-THRESHOLD_VIOLATION: Te2/0/2: Voltage low alarm; Operating value: 0.00 V, Threshold value: 2.96 V.
%SFF8472-5-THRESHOLD_VIOLATION: Te2/0/2: Rx power high warning; Operating value: 1.0 dBm, Threshold value: 0.5 dBm.
This message appears every 10 minutes… Physical layer is checked(and SFP on this link worked perfectly). I already changed IOS on c3750e-universalk9-mz.150-1.SE3.bin(CSCts58073 Bug Details

When moving from OSPFv2 to OSPFv3, there are many changes in the format of the LSAs Type, but the most known changes are: IP prefix informations are no longer carried in Type-1 LSA and Type-2 LSA, new LSAs Type 8 and 9 are added to carry these prefixes.
