Identify Any Communications Lines and ServerNet
Wide Area Network (SWAN) Using the E4SA
2. Determine the TCP/IP processes, subnets, and Internet Protocol (IP) addresses
associated with the LIFs on the E4SA to be replaced.
a. Use the SCF INFO SUBNET command:
b. 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 on the E4SA Planning Worksheet (Continued) on
page 3-5.
Example 3-2 shows the output of this command for NonStop TCP/IPv6. The
following information should help you interpret the display:
The TCP/IPv6 process name is displayed in the first line of output
The subnet name is displayed in the Name column
The logical interface (LIF) name is shown in the Devicename column
The Internet Protocol (IP) address is shown in the *IPADDRESS/DST_IPADDR
column
In Example 3-2, which is a partial output, the E4SA CRU LIF named E10A is
associated with the subnet named SN1 on the TCP/IPv6 process named
$ZZTCP and has the IP address 170.15.200.50.
3. Identify the PAM lines configured on the system.
Use the SCF NAMES command:
NAMES $ZZPAM
Example 3-3 on page 3-8 shows the output of this command. Port Access Method
(PAM) line names are shown under the LINE heading. In this example, which is a
partial output, one PAM line is configured named $TOK1.
Note. You can easily scan for Ethernet 4 ServerNet (E4SA) CRU subnets by looking at the
TYPE column. E4SA CRU subnets are displayed as type ETHERNET.
