Cabletron Systems FRM User Manual - Configuring An Sna Port
Configuring SNA
9-3
●
Node parameters
, which is general configuration that must be done no matter
which protocols will be run in the node. See Chapter 4.
●
RLPs
that will contain the interface(s) to the user device(s), plus Line Interface
Card(s) supporting the ports that will be the interfaces. See Chapter 5.
●
Loaded Protocol(s)
: SNA, as well as the transport protocol: frame relay or X.25;
and LLC2 if connecting to LLC2 devices or if if the transport protocol will be
frame relay. If LLC2 will be used, Bridging must also be loaded. See Chapter 5.
●
If LLC2 is being configured,
LAN port
that will connect to the LAN(s). See
Chapter 5.
●
Frame relay port(s)
and/or
X.25 port(s)
that will connect to a network or frame
relay PVC. See Chapter 7 (frame relay) or Chapter 8 (X.25).
●
SNA port(s)
(page 9-3) that will connect to the user devices, if the connection
will be SDLC.
●
SNA HPADs and TPADs
(described later in this chapter), which identify any
SDLC devices that will communicate with SNA host and terminal devices.
●
LLC2 hosts
(page 9-19) and
LLC2 interfaces
(page 9-26), if the SDLC device(s)
will be connected to the node via a LAN, or if SDLC will be transported over
frame relay per RFC 1490.
●
Subscriber IDs
(page 9-14) to identify the user devices.
●
If LLC2 is being configured,
Virtual LAN ID
(page 9-18). Since an FRM is seen
to LLC2 as a virtual LAN, an ID must be specified to identify the node to LLC2.
Configuring an SNA Port
Once the necessary Node, Line Processor, and protocol parameters have been con-
figured, press
[A]
at the Port Configuration Menu (or
[A], [C], [A]
from the Main Menu.
When prompted, enter:
●
RLP
containing the port:
0–2
. (The default is
0
.) (RLP locations are shown in
Figure 6-1
.)
●
Port
:
0–7
. (The default is
0
.) (Port locations are shown in
Figure 6-2
.)
The display for an existing port will show the configured parameter values, while the
display for a new port will show default database values. (See
Table 9-1
on page 9-6
and
Table 9-2
on page 9-7.) The following figure is an example of an existing port.
