Ipv6Address ::= TEXTUAL-CONVENTION

     DISPLAY-HINT "2x:"

     STATUS       current

     DESCRIPTION

       "This data type is used to model IPv6 addresses.

        This is a binary string of 16 octets in network

        byte-order."

     SYNTAX       OCTET STRING (SIZE (16))

Ipv6AddressPrefix ::= TEXTUAL-CONVENTION

     DISPLAY-HINT "2x:"

     STATUS       current

     DESCRIPTION

       "This data type is used to model IPv6 address

       prefixes. This is a binary string of up to 16

       octets in network byte-order."

     SYNTAX       OCTET STRING (SIZE (0..16))

Ipv6AddressIfIdentifier ::= TEXTUAL-CONVENTION

     DISPLAY-HINT "2x:"

     STATUS       current

     DESCRIPTION

       "This data type is used to model IPv6 address

       interface identifiers. This is a binary string

        of up to 8 octets in network byte-order."

     SYNTAX      OCTET STRING (SIZE (0..8))

Ipv6IfIndex ::= TEXTUAL-CONVENTION

     DISPLAY-HINT "d"

     STATUS       current

     DESCRIPTION

       "A unique value, greater than zero for each

       internetwork-layer interface in the managed

       system. It is recommended that values are assigned

       contiguously starting from 1. The value for each

       internetwork-layer interface must remain constant

       at least from one re-initialization of the entity's

       network management system to the next

       re-initialization."

     SYNTAX       Integer32 (1..2147483647)

Ipv6IfIndexOrZero ::= TEXTUAL-CONVENTION

     DISPLAY-HINT "d"

     STATUS       current

     DESCRIPTION

         "This textual convention is an extension of the

         Ipv6IfIndex convention.  The latter defines

         a greater than zero value used to identify an IPv6

         interface in the managed system.  This extension

         permits the additional value of zero.  The value

         zero is object-specific and must therefore be

         defined as part of the description of any object

         which uses this syntax.  Examples of the usage of

         zero might include situations where interface was

         unknown, or when none or all interfaces need to be

         referenced."
