Verifying a SWAN Concentrator Configuration
This section summarizes the SWAN configuration requirements and recommendations,
and describes the SCF commands used to determine if a SWAN concentrator is
configured correctly.
1. HP recommends that you connect the SWAN concentrator to ports on two different
Ethernet adapters (E4SAs, FESAs, GESAs, or G4SAs) for improved fault
tolerance.
To determine which Ethernet adapters a SWAN concentrator is connected to:
a. Display the TCP/IP processes used by the SWAN concentrator by using the
SCF INFO ADAPTER command:
INFO ADAPTER $ZZWAN.#adapter-name
Make a note of the names of the TCP/IP processes and host IP addresses
used by the SWAN concentrator.
Determining the TCP/IP Processes and IP Addresses for a SWAN
Concentrator on page A-7 shows the output of this command and explains how
to interpret that output.
b. Display the SUBNETs configured on each identified TCP/IP process by using
the SCF INFO SUBNET command:
INFO SUBNET $tcpip-process-name.*
INFO SUBNET $tcpip-process-name.*
Note. Throughout this guide when a distinction between a SWAN concentrator (T3880) and a
SWAN 2 concentrator (T3881) is not required, SWAN concentrator is used as a collective term.
