For the SNALINK LU6.2 interface, the connection and disconnection
of DLC links between the TCP/IP and SNALINK LU6.2 address spaces is
independent of the connection and disconnection of VTAM® links with destination nodes.
You can use the TSO command, NETSTAT DEVLINKS, to determine
the status of the DLC connections between the main TCP/IP address
space and the SNALINK LU6.2 address spaces.
- Status Reported
- Description
- Inactive
- The DLC connection has not been started. You can start one of
the DLC links between TCP/IP and SNALINK LU6.2 with the VARY START
command.
- Issued Connect
- The TCP/IP address space has issued a DLC connection request,
but the SNALINK LU6.2 address space has not yet accepted the connection.
- Connected
- A DLC connection has been successfully established between the
TCP/IP address space and the SNALINK LU6.2 address space.
- Sending Message
- A DLC connection has been successfully established between the
2 address spaces, and a message has been sent by the TCP/IP address
space, but it has not yet been received by the SNALINK LU6.2 address
space.
- Will retry connect
- Either a previously connected DLC connection has been severed,
or the previous connection request was not accepted within the timeout
period. In either case, the TCP/IP address space attempts to resend
another connection request within 30 seconds.
- Status Reported
- Explanation
- Issued connect
- Passive side: SNALINK is waiting for a remote LU to establish
a session.
Active side: SNALINK is trying to establish a session
with a remote LU.
- Will retry connect
- The last session was ended, or the last session attempt failed.
SNAIUCV driver tries the connection again within 30 seconds.
- Connected
- An SNA send session is established. Under normal conditions this
also means a receive session is established or will be established
soon, and communication between the two LUs is possible.
- Sending message
- An SNA send session is established, and there is a DLC SEND currently
outstanding.
