Configuring SNA 8-29
LLC2 Interface Parameters
The following table lists parameters for all interface types. Explanations of some
parameters follow the table.
1 Make sure the port is not configured for backup use only. (See Chapter 6.)
2 Make sure the DLCI is not part of a frame relay DLCI backup group or part of a frame
relay PVC (both described in Chapter 6).
3 See caution at explanation.
4 Configured in LLC2 Host file (described earlier in this chapter).
5 Must be unique among all LAN IDs throughout the network on which this node will
operate.
Interface Type
identifies whether the interface is on a LAN or a frame relay network.
Blocked Port Flag
will cause the port to be enabled ( N ) or disabled ( Y ) at node IPL. The interface will
remain in that state until this parameter is changed or (frame relay interface only) an
on-line enable (
[B], [B], [C] from the Main Menu) or disable ( [B], [B], [A] from the Main
Menu) is performed.
Port Priority
will become the first octet of the Port ID field in Spanning Tree Protocol messages. The
lower the number, the higher the priority that the interface will be given among other
interfaces in the spanning tree.
