SWAN Concentrator Problems
Common SWAN Concentrator Problems
This 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 these SCF commands:
STATUS PATH $ZZWAN.#conc-na
me.1.a
STATUS PATH $ZZWAN.#conc-na
me.1.b
STATUS PATH $ZZWAN.#conc-na
me.2.a
STATUS PATH $ZZWAN.#conc-na
me.2.b
STATUS PATH $ZZWAN.#conc-na
me.3.a
STATUS PATH $ZZWAN.#conc-na
me.3.b
where conc-nam
e 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).
Check the SWAN kernel code
version.
To display the version of the SWAN kernel code
in
stalled on a SWAN concentrator, use this
command to display the EMS log on your terminal:
EMSDIST CO $0, TY P, TE [#m
yterm]
Next, initiate a BOOTP sequence by resetting the
SW
AN concentrator or by adding the SWAN
concentrator using WAN subsystem SCF
commands. An EMS message similar to this will be
displayed on your terminal:
TANDEM.WANMGR.H01 001502 WANBoot: BOOTP
received for SWANB TRACKID VOZN6H, CLIP 1,
IP Address 192.168.111.201, Path A
VPROC: T7954G01^18SEP2002^AAL^R002

The SWAN kernel version is shown in line beginning
with VPROC.
