Customer want to configure lambda 10G, we installed LBES boards in metro 6100 equipments and LSX boards in OSN 6800, lambda present problems and dont up. We have loops from OSN 6800-1 to router-1 and router-1 detect lambda up but we have loop from OSN 6800-1 to router-2, this router dont detect lambda up. If we have loop from OSN 6800-2 to router-2 lambda up. So we detect problem was between OSN 6800-1 and OSN 6800-2, we check and problem was not physical. Customer told us that OSN 6800-2 has configurate LSX board in 10G WAN mode, we check OSN 6800-1 LSX board and it has the same configuration.
