SWAN Concentrator Problems
SWAN Concentrator Problems
This subsection provides ServerNet wide area network (SWAN) concentrator
troubleshooting guidelines and identifies common SWAN concentrator problems.
Troubleshooting Check List
Use the check list provided in Table 20-8 to solve problems related to SWAN
concentrators.
Expand Layer 2
protocol
You can use the SCF STATS LINE command to examine Layer 2
statistics. Figure
20-1 on page 20-3 (earlier in this section) is an example
of an SCF STATS LINE command.
Table 20-8. SWAN Concentrator Problem-Resolution Check List (page 1 of 2)
Task Procedure
Check the SWAN concentrator. To determine the state of a specific SWAN
conce
ntrator, use this WAN subsystem SCF
command:
STATUS ADAPTER $ZZWAN.#conc
-name
where conc-nam
e is the name of the SWAN
concentrator (ADAPTER object). To determine the
status of all the SWAN concentrators on a system,
use this WAN subsystem SCF command:
STATUS ADAPTER $ZZWAN.*
If the SWAN concentrator is not operational, it must
be
started (see the WAN Subsystem Configuration
and Management Manual
for details.
Check the communications line
interface processors (CLIPs) on
the
SWAN concentrator.
To determine the state of the CLIPs on a specific
SWAN concentrator, use these SCF commands:
STATUS SERVER $ZZWAN.#conc-
name.1
STATUS SERVER $ZZWAN.#conc-
name.2
STATUS SERVER $ZZWAN.#conc-
name.3
where conc-name is the name of the SWAN
concentrator (ADAPTER object). If a CLIP is not
operational, it must be started. See the WAN
Subsystem Configuration and Management Manual.
