SWAN Concentrator Problems
Common SWAN Concentrator Problems
The following is a list of common SWAN concentrator problems:
•
The SWAN concentrator’s Ethernet ports are connected to the wrong Ethernet
segments.
•
One or both of the SWAN concentrator’s Ethernet ports are connected to a
nonoperational Ethernet segment.
•
Both of the SWAN concentrator’s Ethernet ports are connected to the same
Ethernet segment, and the alternate NonStop TCP/IP process (ALTTCPIP
attribute) is configured as a NonStop TCP/IP process on the same segment. The
SNMPCODE file will not download in this configuration. If you must connect both
Check the Ethernet paths configured
for each CLIP on the SWAN
concentrator.
To determine the state of the Ethernet paths
configured for each CLIP on a specific SWAN
concentrator, use the following SCF commands:
STATUS PATH $ZZWAN.#conc-name.1.a
STATUS PATH $ZZWAN.#conc-name.1.b
STATUS PATH $ZZWAN.#conc-name.2.a
STATUS PATH $ZZWAN.#conc-name.2.b
STATUS PATH $ZZWAN.#conc-name.3.a
STATUS PATH $ZZWAN.#conc-name.3.b
where conc-name is the name of the SWAN
concentrator (ADAPTER object). If an Ethernet path
is not operational, it must be started. See the WAN
Subsystem Configuration and Management Manual
for details.
Check the SWAN kernel code
version.
To display the version of the SWAN kernel code
installed on a SWAN concentrator, use the following
command to display the EMS log on your terminal:
EMSDIST CO $0, TY P, TE [#myterm]
Next, initiate a BOOTP sequence by resetting the
SWAN concentrator or by adding the SWAN
concentrator using WAN subsystem SCF
commands. An EMS message similar to the
following will be displayed on your terminal:
TANDEM.WANMGR.F40 001502 WANBoot:
BOOTP received for SWAN14 Track Id X017FF,
CLIP 2, IP Address 172.16.45.25, Path B
VPROC: T7954G01^15NOV96^25NOV96G01,
Firmware Updates not initiated for PATH B
The SWAN kernel version is shown in line beginning
with VPROC.
