If no packets have been discarded, check to see if the filters are properly configured. Try the
following:
following:
a.
From Manage Mode, issue the ipfilt command. Check the configured packet types, as well
as the configured filters:
•
as the configured filters:
•
For packet types, it is important to verify that the contents of the packet in question are
indeed correctly specified (IP Addresses, Protocol, TCP Ports, etc.).
indeed correctly specified (IP Addresses, Protocol, TCP Ports, etc.).
•
For configured filters, keep in mind that component conditions are executed in the order
in which they appear in the configuration. It is possible that a packet is not being
discarded as expected if a previous condition matches that packet with an action of
forward.

Check to see if the filters are properly applied:
•
•
For global filters, use Manage Mode’s ipfilt command. Check the Apply Global
Forwarding Filter option.

•
For filters applied on a per-device basis, use Manage Mode’s device command. Check

For network interface filters, check the IP interface information in CFGEDIT (Options,
IP Configuration, IP Interface).

c.
Make configuration changes as necessary.

If you are still experiencing problems:
a.
Check the status of the Exception Filter (using Manage Mode, ipfilt command). The
Exception Filter overrides all other filters. If the Exception Filter is enabled, this could be
the problem.

With per-device and network interface filters, it is necessary that the packet in question
truly flows through the desired application point. Try this test:

•
Disable the per-device and network interface filters.
•
Apply each filter in question globally.
•
When desired IP packets are received, it is guaranteed that they will pass through the
filter in question. You can then analyze the effects in isolation. Your findings will be
helpful if you need to call Customer Support.

When test completed, turn off the trace. Issue the administrative console command:

1.
Determine if IP RIP processing has been initialized by viewing the system messages. On the
administration console type:
administration console type:

The

command displays the current system messages. Look for the following IP RIP message
among the system message:
