Cisco Cisco Network Assistant Version 3.0 Release Notes

This cluster caveat applies to the all the devices described in the 

CSCef48257

After the cluster command device is reloaded, it might not be able to re-establish communication 
with the cluster members connected through its routed ports.

This is the workaround. Follow these steps:

Use the no cluster run global configuration command on the cluster command device and the 
cluster members that have lost connectivity to the command device. 

Use the cluster member global configuration command to add the cluster members back to the 
cluster.

If a Catalyst 2970 switch is a cluster command device and a Catalyst 3750 or 3550 switch is a cluster 
member, enabling IGRP on a network on the Catalyst 3750 or 3550 switch creates a Premature EOF 
error.

There is no workaround. Make the Catalyst 3750 or 3550 switch the command device.

This section describes the resolved caveats.

These caveats were resolved in this release:

When a Catalyst 3750 stack member leaves or joins the device stack, the entire stack no longer 
disappears from the Topology view.

cluster now appears.

An error no longer occurs when you modify the port settings of multiple ports by using the Modify 
Port Settings window launched from the popup menu of the Front Panel view.

In the Topology view, the EtherChannel links between two Catalyst 4500 series switches now 
correctly appear in red (blocked) instead of green (forwarding).
