Troubleshooting an IronStack
5
If the send message types: field is empty, it means that stack enable has not been configured.
If the number of Recv IPC packets increases, but there are no Recv message types, then the
packets are being dropped for various reasons, including the wrong IPC version, or a checksum
error. The Possible errors field will list reasons for packet loss.
NOTE
A small “***state not ready” count is normal, but if it continues to increase a problem is
indicated.
6. If the results of a show stack command show other stack members, but lists them as
non-operational, this could be due to an image mismatch, or a configuration mismatch. In the
event of an image mismatch, you can download the correct images to the entire stack from the
Active Controller. Refer to “Configuration mismatch” on page 155 for more information about
configuration mismatches.
NOTE
If your intended stacking ports are connected in a ring topology, they will not all appear to be in
the forwarding state because of spanning tree, but secure-setup can still build the stack.
7. If you run out of flash memory while doing a write memory, your stack devices may contain very
large startup-config.v4 or startup-config.old files, which are preserved for recovery purposes
(refer to “Unconfiguring an IronStack” on page 130 for more information). If you do not need
these files, you can delete them using the flash delete command. Enter the show dir command
to see all flash files.
8. Check to be sure you do not have any stacking to non-stacking connections. If you see the
following message.
Warning! Proc ???? packet in 2m from 0012.f2222.8300, Wrong dev/port: dev=4,
port=18, DSA=4971100 497--E
You might have stacking to non-stacking port connections
This indicates that you may have a connection between a stacking port and a non-stacking
port. This message will appear every 10 minutes after the first display. If you see this message
once only, and your connections are correct, your stack should be operating properly. Only
repeat displays of this message indicate a problem.
Troubleshooting image copy issues
The copy tftp flash command copies the image to all stack units including the Active Controller. The
copy flash flash command copies the image from the primary or secondary flash on the Active
Controller to the primary or secondary flash image of a stack member, respectively. If you are
unable to copy an image to one or more stack units, check the following:
• Make sure the unit is actually part of the stack. Use the show stack command.
• If a unit joins a stack after the image copy command was issued, you will need to copy the
image to this unit separately.
