Hi all,
when i issued by sh arp on cat4507, some of the arp entry showed me it's mac address 0000.0000.0000.
actually, these hosts not turn on. but i can ping these address. that is, someone response to me with the ping.
here is the output on cat4507.
Cat4507>
Cat4507>sh arp | i 0000.0000.0000
Internet 172.29.211.78 2 0000.0000.0000 ARPA Vlan101

Cat4507>sh mac-add
Cat4507>sh mac-address-table | i 0000.0000.0000

Hi john...
The 0000.0000.0000 indicates that the router is currently unaware of the MAC address...
Can you examine arp packets by using following command.
debug arp
Let me know how it goes!
