Cabletron Systems CSX1200, CSX1000 If you are still experiencing problems, IP RIP Initialization

PROBLEM DIAGNOSIS

IP RIP

a.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.).

b.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.

2.Check to see if the filters are properly applied:

a.For global filters, use Manage Mode’s ipfilt command. Check the Apply Global Forwarding Filter option.

b.For filters applied on a per-device basis, use Manage Mode’s device command. Check to see if filters properly applied.

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

3.Make configuration changes as necessary.

If you are still experiencing problems:

1.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.

2.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:

a.Disable the per-device and network interface filters.

b.Apply each filter in question globally.

c.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.

If the IP filters are properly configured, and the system is still not correctly discarding packets, contact Customer Support.

This section provides guidance for diagnosing IP RIP operational problems.

IP RIP INITIALIZATION

Problem:

The CyberSWITCH does not display the correct IP RIP Initialization messages. Instead, it displays one or more of the following message:

[IP RIP] Initialization failed, unable to allocate buffers [IP RIP] Unable to open RIP/UDP port 512

Action:

There is an unexpected condition present within the CyberSWITCH software. Contact Customer Support.
