Replacing an E4SA CRU

identifying Expand-over-IP lines, SWAN concentrators, and WAN subsystem IOPs.
Tip: 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.
1 Determine the names of the logical interfaces (LIFs) and the physical
interfaces (PIFs) associated with the E4SA CRU to be replaced.
Use the SCF INFO LIF command:
INFO LIF $ZZLAN.*
Scan the output of the command for the name of the E4SA CRU to be
replaced. Make a note of the LIF names and PIF names.
The example shows the output of this command.
2 Determine the TCP/IP processes, subnets, and Internet Protocol (IP)
addresses associated with the LIFs on the E4SA CRU to be replaced.
Use the SCF INFO SUBNET command:
INFO SUBNET $*.*
Scan the output of the command for each LIF you identified in Step 1 and
then find the associated TCP/IP processes, subnets, and IP addresses.
Make a note of this information.
The example shows the output of this command.
3 Identify the PAM lines configured on the system.
Use the SCF NAMES command:
NAMES $ZZPAM
The example shows the output of this command.
