  47. Monitoring AppleTalk (cont.) Router#show appletalk globalsAppleTalk global information: Internet is incompatible with older, AT Phase1, routers. There are 5 routes in the internet. There are 5 zones defined. Logging of significant AppleTalk events is disabled. ZIP resends queries every 10 seconds. RTMP updates are sent every 10 seconds. RTMP entries are considered BAD after 20 seconds. RTMP entries are discarded after 60 seconds. AARP probe retransmit count: 10, interval: 200 AARP request retransmit count: 5, interval: 1000. DDP datagrams will be checksummed. RTMP datagrams will be strictly checked. RTMP routes may not be propagated without zones. Routes will not be distributed between routing protocols AppleTalk EIGRP is not enabled IPTalk uses the udp base port of 768 (Default). Alternate node address format will not be displayed. Access control of any networks of a zone hides the zone.
