I am seeing a recurring problem at my site and have no clue how to solve it.
When connecting a networkable printer, it takes long periods of time before the printer will start talking to the network. More specifically, the printer gets connected link and activity lights on and blinking. The switch interface is configured properly. When I do a "show mac-address dynamic" it shows the correct MAC address. Under the protocols section it lists just "other" and until it lists "ip" I am unable to talk to the printer. Sometimes it may take hours before it starts talking. I believe this is switch related, because it happens with both different makes and models of printers. I am clueless at this point, any help would be greatly appreciated.
When replacing network printers, and using the same IP address, you often need to log into the router on the subnet (default gateway), and clear arp.
ARP cache entry timeout is 4 hours, and printers often just sit and wait for someone to talk to them, so the router keeps sending to the old mac address.
