Identify Any Communications Lines and ServerNet Wide Area
Network (SWAN) Using the E4SA
The subsystems and utilities that use the SLSA subsystem to access an E4SA are
illustrated in Figure 1-2 on page 1-7.
The following procedure should help you identify the subsystems and utilities that are
configured to use an E4SA. 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 interfaces (LIFs) and the physical interfaces
(PIFs) associated with the E4SA 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 E4SA to be replaced.
Make a note of the LIF names and PIF names.
Example 3-1 shows the output of this command. Logical interface (LIF) names
are shown in the Name column and physical interface (PIF) names are shown
in the PIF column. The name of the Ethernet 4 ServerNet adapter (E4SA)
CRU is the first part of the PIF name (for example, E0153).
The PIF name indicates the physical port on the E4SA CRU. For example, the
PIF named E0153.0.A. identifies port ENET 0A and the PIF named E0153.0.B
identifies port ENET 0B on the E4SA named E0153. In this example, the LIFs
associated with the E4SA CRU named E0153 are named L018, L019, L01A,
and L01B.
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.
