Static Definitions or Pooled Definitions:
Each time a client connects, they can be given a specific LU assignment from a specific
Host Circuit, or they can be given a session from a session pool. Session pools allow the
same LU resource be shared by multiple users on a first-come-first-serve basis. Session
pools consist of any number of LUs from one or more Host Circuits that have been
grouped together and assigned a name. Each LU can be assigned to one or more pools
and can be statically mapped as well. Usually however, you will want to have them
assigned to either a pool or a static assignment. For most environments, consoles are
given static assignments and VTAM sessions may frequently be assigned to pools. In the
case where you want to provide a connection menu of consoles, you would normally
create a pool (of one session) associated to each console. (The menu only displays a list
of pools.)
Encryption Used or Not:
Whether Encryption is used or not is configurable on a Listening Port by Listening Port
basis. This option must be matched by the client exactly or no connection will be
accepted.
Connection Password Requirement:
User ID and Passwords can be required to connect to the CCA-3074 if desired, and is
configurable. If the User ID or Password gets changed while a client is currently attached,
having previously attached using the previous User ID and Password, the session remains
connected until such time the client disconnects or is forcibly disconnected by the
administrator. Their next connection will require the new User ID and Password.
Resource Assignment Methods:
Resources can be requested by the client or assigned by the CNA-3000. Methods used to
assign resources include:
Client IP Address
Client Subnet Address
Listening (TCP) Port that the Client Connects To
Specific Resource Requested Using a Predefined Format
Specific Resource Requested Using a Nickname
Selected from a Menu Presented to the Client
