How do I troubleshoot Zip Storm on an AppleTalk network?
A. In order to fix a node that does not respond to ZIP requests, follow these steps: • Issue the debug apple zip command and identify the network for the zone requested by nearby routers. • Identify the router that causes the excessive ZIP traffic. • Issue the show appletalk route command to view the AppleTalk routing table. • Verify that a network exists in the routing table even when the display shows that no zone is set. If you find a network where no zone is set, a node on that network is probably not able to respond to ZIP requests and causes the ZIP storm. • Determine why the node does not respond to ZIP requests. Access lists or other filters might be the cause. • In order to locate a problem access list or filter, apply one AppleTalk filter at a time with these commands until you can no longer create connections: • appletalk access-group [access list number] • appletalk distribute-list [access list number] in • appletalk distribute-list [access list number] out • appletalk getz
