The ALE status provides information on the ALE configuration and state. The ~iramdepth is used to determine how IPv6 entries are stored in the table. IPv6 entries are stored in two entries where IPv6 Entry hi is designated by the odd slice index and lo is designated by the even slice index. The slice index is above the ram depth like {SlixeIndex,RamIndex}. So for a 64 deep RAM index of 0x005, the Hi portion of the IPv6 entry is located at 0x005|0x040 and the Lo portion is located at 0x005&(~0x040).
