3. Troubleshooting Functional Failures During Operation

#1
If you execute the
dump bsu command, do not execute any more commands until a log entry
is output stating that collection of the memory dump file is complete. Also, the second time
you execute the
dump policy command or the dump bsu command, the memory dump file
you collected the first time is deleted, so be sure to save the memory dump file before
executing the command for the second time.
#2
If you execute the
dump psp command, do not execute any more commands until a log entry
is output stating that collection of the memory dump file is complete. Also, the second time
you execute the
dump policy command or the dump psp command, the memory dump file
you collected the first time is deleted, so be sure to save the memory dump file before
executing the command for the second time.
Table 3-89: Action to take when packets are not forwarded in policy-based routing for
AX3800S, AX3650S, or AX3640S
6 Check the path switch-back operation setting of
policy-based routing
• Execute the
show ip cache policy
command, and check the
Recover item.
If the setting is Off, path switch-back operations are not
performed, and thus the path is not being re-selected.
Execute the
reset policy-list command to re-select
the path.
If the setting is
On, go to No. 7.
7 Check if a network communication failure has
occurred in the destination interface
• See 3.7 IPv4 network communication
failures.
If a communication failure has occurred, follow the
instructions in the referenced section.
If a communication failure has not occurred, go to No. 8.
8 Collect analysis information
• For AX6700S
Execute the
show tech-support command,
the
dump policy command, and then the
dump bsu command, twice in that order.
#1
• For AX6600S or AX6300S
Execute the
show tech-support command,
the
dump policy command, and then the
dump psp command, twice in that order.
#2
Send the information you collected to the support center.
No. Items to check and commands Action
1 Check the operating status of the filter for which
the policy-based routing list information is set
• Execute the
show access-filter
command, and in
matched packets :,
check whether the number of packets matches
the filter condition.
If the number of packets that could not be transmitted
differs from the
matched packets value, it is possible that
the filter detection conditions are incorrect, causing implicit
discards.
Revise the filter settings.
If the number of packets that could not be transmitted is the
same as the
matched packets value, go to No. 2.
2 Check the operating status of the policy-based
routing group
• Execute the
show ip cache policy
command, and check the display status of *>.
If the status is not displayed, the group might be in the
process of starting, or in default operation, causing default
forwarding or discards to be performed.
To check if the group is in the process of starting, go to No.
3.
If the status is displayed, go to No. 4.
