-- the TCP over IPv6 Connection table

-- This connection table contains information about this

-- Only connections between IPv6 addresses are contained in
-- this table.  This entity's connections between IPv4
-- endpoints are contained in tcpConnTable.

ipv6TcpConnTable OBJECT-TYPE
   SYNTAX      SEQUENCE OF Ipv6TcpConnEntry

ipv6TcpConnEntry OBJECT-TYPE

   STATUS      current
   DESCRIPTION
        "A conceptual row of the ipv6TcpConnTable containing
         information about a particular current TCP connection.
         Each row of this table is transient, in that it ceases to
         exist when (or soon after) the connection makes the transition
         to the CLOSED state.

         Note that conceptual rows in this table require an additional
         index object compared to tcpConnTable, since IPv6 addresses
         are not guaranteed to be unique on the managed node."

         is willing to accept connections for any IPv6
         address associated with the managed node, the value

ipv6TcpConnIfIndex OBJECT-TYPE
   SYNTAX     Ipv6IfIndexOrZero
   MAX-ACCESS not-accessible
   STATUS     current
   DESCRIPTION
        "An index object used to disambiguate conceptual rows in
         the table, since the connection 4-tuple may not be unique.

         If the connection's remote address (ipv6TcpConnRemAddress)
         is a link-local address and the connection's local address

         (ipv6TcpConnLocalAddress) is not a link-local address, this
         object identifies a local interface on the same link as
         the connection's remote link-local address.

         Otherwise, this object identifies the local interface that
         is associated with the ipv6TcpConnLocalAddress for this
         TCP connection.  If such a local interface cannot be determined,
         this object should take on the value 0.  (A possible example
         of this would be if the value of ipv6TcpConnLocalAddress is ::0.)

         The interface identified by a particular non-0 value of this
         index is the same interface as identified by the same value
         of ipv6IfIndex.

         The value of this object must remain constant during the life
         of the TCP connection."

   STATUS     current
   DESCRIPTION
        "The state of this TCP connection.

         The only value which may be set by a management station is
         deleteTCB(12).  Accordingly, it is appropriate for an agent
         to return an error response (`badValue' for SNMPv1, 'wrongValue'
         for SNMPv2) if a management station attempts to set this
         object to any other value.

         If a management station sets this object to the value
         deleteTCB(12), then this has the effect of deleting the TCB
         (as defined in RFC 793) of the corresponding connection on
         the managed node, resulting in immediate termination of the
         connection.

         As an implementation-specific option, a RST segment may be
         sent from the managed node to the other TCP endpoint (note
         however that RST segments are not sent reliably)."
