Interface ID to ifIndex lookup table

Given an interface ID, the interface ID to ifIndex lookup table returns the ifIndex value. The table is useful for mapping a known interface to the corresponding ifIndex value. The contents of the interface ID to ifIndex lookup table can only be accessed using GET operations. Unlike other SNMP tables, this table does not support GET-NEXT operations. If you try to walk the table using GET-NEXT, no rows will be returned.
