Partner LU as port of entry (POE)

You can use the APPCPORT general resource class to protect the port of entry (POE). There are two possible formats for the resource name in the APPCPORT class:

If the APPC LU definition has enabled network-qualified names support (by specifying the NQN option on the LUADD statement), the format for the resource name is:
```
netid.luname
```
where:

netid

Is a network name consisting of 1 - 8 characters. The first character must be alphabetic.

luname

Is an LU name consisting of 1 - 8 characters.
If APPC network-qualified names support is not enabled, the format for the resource name is:
```
luname
```
where:

luname

Is an LU name consisting of 1 - 8 characters. The first character must be alphabetic.

Failure to specify the correct LU name format could result in a security exposure. For more detailed information, see z/OS MVS Planning: APPC/MVS Management.
