A conceptual row in the alHostTable. The hlHostControlIndex value in the index identifies the hlHostControlEntry on whose behalf this entry was created. The first protocolDirLocalIndex value in the index identifies the network-layer protocol of the address. The nlHostAddress value in the index identifies the network- layer address of this entry. The second protocolDirLocalIndex value in the index identifies the protocol that is counted by this entry. An example of the indexing in this entry is alHostOutPkts.1.783495.18.4.128.2.6.6.34. Note that some combinations of index values may result in an index that exceeds 128 sub-identifiers in length, which exceeds the maximum for the SNMP protocol. Implementations should take care to avoid such combinations.
