Identify Any Communications Lines and ServerNet Wide Area
Network (SWAN) Using the FESA
The subsystems and utilities that use the SLSA subsystem to access an FESA are
illustrated in Figure 1-2 on page 1-8.
The following procedure should help you identify the subsystems and utilities that are
configured to use an FESA. Specific instructions are provided for identifying the
following:
•
Expand-over-IP lines
•
SWAN concentrator
•
WAN subsystem IOP
Perform the following steps:
1. Determine the names of the logical interface (LIF) and the physical interface (PIF)
associated with the FESA to be replaced.
a. Use the SCF INFO LIF command:
INFO LIF $ZZLAN.*
b. Scan the output of the command for the name of the FESA to be replaced.
Make a note of the LIF name and PIF name.
Example 3-1 shows the output of this command. The LIF name is shown in the
Name column and the PIF name is shown in the PIF column. The name of the
Fast Ethernet ServerNet adapter (FESA) CRU is the first part of the PIF name
(for example, E0153).
The PIF name indicates the physical port on the FESA CRU. For example, the
PIF named E0153.0.A. identifies port ENET 0A on the FESA named E0153. In
this example, the LIF associated with the FESA CRU named E0153 is named
L018.
Note. You will need to make a note of the information you obtain during this procedure. You
can record this information on the planning worksheet provided or you can use the SCF LOG
command to capture both the command and the display that is produced to a file. To start
logging, type LOG logfilename at the SCF prompt. To stop logging, type LOG at the SCF
prompt.
